[edit] Failed "good article" nomination

Upon its review on March 2, 2008, this good article nomination was quick-failed because it:

contains cleanup banners including, but not limited to, {{cleanup}}, {{wikify}}, {{NPOV}}, {{unreferenced}}, etc, or large numbers of {{fact}}, {{clarifyme}}, {{huh}}, or similar tags

thus making it ineligible for good article consideration.

This article did not receive a thorough review, and may not meet other parts of the good article criteria. I encourage you to remedy this problem (and any others) and resubmit it for consideration. If you feel that this review is in error, feel free to take it to have it reassessed. Thank you for your work so far.— Epass (talk) 18:13, 2 March 2008 (UTC)


I am the one who put up the GA nomination, and I'd like to let everyone know that I am challenging all of that unsourced information labeled by {{fact}} tags and will remove it. If you can find the citations or wish to debate some of it, then say so here, and please don't go aimlessly reverting the article because you think I'm vandalizing it. Redphoenix526 (Talk) 19:52, 4 March 2008 (UTC)

Good work so far. The only comment I have (from a quick scan through) is that the two GameFAQS citations should be replaced with different ones, as they are not reliable sources, with one being a user-submitted review, and the other being a user-submitted FAQ. Dreaded Walrus t c 22:22, 4 March 2008 (UTC)
I had not noticed the GameFAQs sources in that list. Yes, they should be removed. Redphoenix526 (Talk) 01:34, 5 March 2008 (UTC)

I'd like to renominate it for GA status in the next couple of days. Redphoenix526 (Talk) 19:26, 5 March 2008 (UTC)

I'd hold off on it until all of the Refs have proper Citewebs on them, because it will pointed out during FA assessment. Not sure if it can be failed for it but it would be better to go in there with as few obvious flaws as is possible. - X201 (talk) 20:08, 5 March 2008 (UTC)


I've changed some occurrences of Genesis to Mega Drive in the article purely because I know FA will pick up on the fact that Mega Drives and Genesis were used as interchangeable words for the same item. I've left Genesis intact in the North American section and in places where it was the NA version of the console that was specifically being talked about. This isn't some kind of dastardly plot to deprive North America of it's Genesis and to say it never existed, I'm just trying to make the FA process as smooth as possible. - X201 (talk) 20:05, 5 March 2008 (UTC)

I think Redphoenix is actually talking about Good Article, but still, your changes certainly improve the article, and I agree also with your reasoning. Dreaded Walrus t c 20:19, 5 March 2008 (UTC)
Yeah, I was talking Good Article, which is why I said GA. But I like your thinking anyway, X201, and maybe we should nominate it for FA in a little while. In the mean time, any votes for relisting for GA status? Redphoenix526 (Talk) 02:32, 6 March 2008 (UTC)
I still think the two GameFAQs references may well need replacing with better sources. But other than that, I'm no expert on GA/FA criteria, so it's probably best to get X201's opinion on that. Dreaded Walrus t c 02:35, 6 March 2008 (UTC)
I've sorted out some of the web citations, but I've also noticed a lot of statements unsourced. See also Web link checker which reveals a few problem links. Overall the article is pretty well written, but there are some areas with stubby paras. All these issues, and more, will be picked up in any GA/FA nomination. I suggest a peer review before considering a GA nomination. -- Nreive (talk) 10:35, 6 March 2008 (UTC)

[edit] Good article reassessment

This article has been nominated for good article reassessment to determine whether or not it meets the good article criteria and so can be listed as a good article. Please add comments to the article reassessment page.

The guys at WP:GAR recommended we relist at WP:GAN and renominate the article entirely, so I'm going to do that now. I think the article is cleaned up enough now. Redphoenix526 (Talk) 17:13, 12 March 2008 (UTC)
I don't think it'll reach GA without those spec tables being turned into prose first. But it's worth a try. Crimsonfox (talk) 02:59, 16 March 2008 (UTC)
I'm not sure it will either, but that's what the guys at WP:GAR said to do, relist it. I didn't send it in to WP:GAR, but it sounds like they think it should be relisted. Guess we'll see what happens, and chances are if it's a table, we'll be put on hold to fix it really quick. Redphoenix526 (Talk) 03:26, 16 March 2008 (UTC)
At the very least we'll get an indication of the sections of the article that need attention. - X201 (talk) 08:24, 16 March 2008 (UTC)
That's true, so we're getting help one way or another. Redphoenix526 (Talk) 16:08, 16 March 2008 (UTC)

I did ask a while back for someone with more knowledge of the technical side of things to read over the prose I wrote up to check that if it mzde sense or not. Took me freakin' ages to write all that up and trying to actually understand it all while I was doing it. It's a shame really cause it's only the memory and I/O section that needs be to finished really. I left the tables there before just in case someone wanted to add anything from them before we got rid of them. Crimsonfox (talk) 06:04, 17 March 2008 (UTC)

Here. I'll finish it now and get rid of the tables. Of course, it can always be reverted if it doesn't work. Redphoenix526 (Talk) 23:05, 17 March 2008 (UTC)
Okay, I've finished it, but I think it needs a little copyediting. This is the first time I've ever converted a tech table into prose, so I don't think my English is perfected with it yet (funny, I'm a native speaker). Redphoenix526 (Talk) 23:43, 17 March 2008 (UTC)
Good job!. The only thing I'm certain we'll get pulled up on is words like "playfield". I've got a pretty good idea what it means but a non-techy person will trip over it. any objections to changing words like playfield to "screen" or "backgrounds" ? - X201 (talk) 10:14, 18 March 2008 (UTC)
None at all. This is what I meant by copyediting, stuff like this needs tweaked. I still think it will pass the good article nomination, but every little bit helps. Redphoenix526 (Talk) 17:32, 18 March 2008 (UTC)

This article was nominated for good article reassessment to determine whether or not it met the good article criteria and so can be listed as a good article. The discussion was closed in preparation for renomination at Wikipedia:Good article nominations. Please see the archived discussion for further information.

[edit] Second Sega console sold outside of Japan?

That's not true. The Sega SG-1000 was not sold in North America, but it was in Oceania and some European countries. —Preceding unsigned comment added by 88.22.108.46 (talk) 09:43, 24 March 2008 (UTC)

I had a similar question about the thing about the "fifth console" thing. I've looked at the article for Sega and there's nothing mentioned about any systems other than the Master System, Genesis, Saturn, and Dreamcast. Can someone talk about how like, I don't know, what systems predated it? Like not just the Master System? And if it IS the fifth console, how come the preceding four other than the Master System aren't mentioned in the main article? Can someone fix this PLEASE?! BTW, I'm glad someone finally put down a source for the last game made for the Genesis because it's been driving me insane trying to prove to my boyfriend that there was a game made for the Genesis in Brazil and we both really wanted to know what it was, but everywhere I looked, it all just kept referring verbatim to Wikipedia. ForestAngel (talk) 07:17, 14 May 2008 (UTC)

Take a look at Sega SG-1000 and Sega SC-3000. Some consider the SC-3000 and 3000H (mentioned in the 3000 article) a Sega console, but in reality they're computers. So really it's a question of perspective. I'd like to ask for consensus here first about this before changing anything. Red Phoenix flame of life...protector of all... 02:34, 16 May 2008 (UTC)

[edit] Do we have enough sources?

I'm afraid some of the sections might not be well sourced enough, especially in the technical specifications area. We might get nailed for original research on that, even if it's really not. Red Phoenix (Talk) 14:42, 27 March 2008 (UTC)

[edit] GA review

I have reviewed your article and after checking all of your references, many of them appear to be unreliable. However, after checking some of the other console articles (namely the Super Nintendo Entertainment System), I have discovered some of their references appear questionable as well. Of the references I found that stuck out to me, these include 2, 3, 4, 11, 13, 15, 18, 19, 20, 21, 22, 28, 32, 33, 41, 46, 47, 48, 49, 52, 54, 55, 56.

Y Done Among these are sites from angelfire, gamefaq guides,

  • I've already trashed these two sources and replaced/cut the information sourced by them. Red Phoenix (Talk) 18:59, 3 April 2008 (UTC)

and other unverifiable/unreliable sites.

Y Done Also, I found refs 12 and 24 to be broken.

  • Also trashed/replaced these sources. Red Phoenix (Talk) 18:59, 3 April 2008 (UTC)

Because I am unsure of the reliability of these references, I am requesting a 2nd opinion from others regarding the reliability of the above references in question. In the meantime, I recommend searching for more reliable sources. Here are some other issues to consider in the meantime:

  • Y Done Try to integrate the lone sentence in the lead into one of the other paragraphs.
  • Y Done In Launch -> NA, "making it the second console to feature a 16-bit CPU (the first one being the Mattel Intellivision) and the first to feature single-instruction 32-bit arithmetic" - This needs to be cited.
  • That statement was in the wrong place anyway and looked to be original research, so I cut it. Red Phoenix (Talk) 15:04, 2 April 2008 (UTC)


  • Y Done In Launch -> Europe, try to consolidate the marketing details into a single paragraph.


  • Y Done In Launch -> Brazil, consolidate all of the sentences into one paragraph.


  • Y Done In Console wars, "However, after the release of the PC-Engine CD add-on and the Nintendo Super Famicom, the Mega Drive soon lost ground in the US market." - this needs to be cited.


  • Y Done In Console wars, "One of Sega's most famous advertisements in North American media was its slogan "Genesis does what Nintendon't",[29] [15] which showcased the graphics advantage that the Genesis held against the aging NES." - this statement is awkward by itself. Try to integrate it into the rest of the article.
  • Y Done In 32-bit era and beyond, the first paragraph needs to be cited.
  • Y Done In 32-bit era and beyond, "In the UK the last stocks of the Mega Drive II were sold by the end of 1999." Needs to be cited.
  • Removed instead, possible original research. Red Phoenix (Talk) 18:07, 1 April 2008 (UTC)
  • Y Done In 32-bit era and beyond, "the successful and long-lived Sega Master System" - Reword to sound less peacock-like.


  • Y Done In Emulation, the first two sentences should be cited.
  • Seemed more like original research, so I just cut it. Red Phoenix (Talk) 23:38, 1 April 2008 (UTC)
  • Y Done This section also needs more references overall,
  • Y Done some parts lack any at all (e.g. "During his keynote speech at the 2006 Game Developers Conference...").
  • Y Done Master system compatibility
  • Y Done Peripherals
  • Y Done Variations
  • Y Done tech specs could use all use more references. Some parts of these sections are largely uncited.
  • Y Done Right now, modifications is mostly independent research, references are needed here or the section needs to go entirely.

Thank you for your patience. -- Noj r (talk) 05:19, 1 April 2008 (UTC)

If the sites are unreliable, they must be replaced with reliable sites of the article can't get GA I think. Epass (talk) 11:02, 1 April 2008 (UTC)
Alright, after speaking to some other editors, I feel it would alright to put this on hold for a week to address the issues. Continue to implement the fixes noted above and try to find reliable sources for your statements. I also noted someone went through and layed some fact tags down. Since they were put there before the review I will ignore them, but I recommend finding references for them. I will check this page regularly for changes, just message here when you feel you are done. Good Luck -- Noj r (talk) 17:17, 1 April 2008 (UTC)
I guess someone layed the fact tags down to give us a guide of what needs citations as per your suggestions. We'll get right on them. Red Phoenix (Talk) 18:09, 1 April 2008 (UTC)
It was me. I was a bit quick out of the blocks this morning. - X201 (talk) 18:23, 1 April 2008 (UTC)

Well, the checklist has been finished. While I haven't seen every reference personally, we have rid ourselves of the most unreliable sources: angelfire and GameFAQs, trashed the broken links, and cited more that was not cited previously. It might be done at this point, but I want to let X201 read over it first and tell me what he thinks before I can call it ready to be looked at again. Red Phoenix (Talk) 19:17, 3 April 2008 (UTC)

That is fair, I do recommend checking all of the references for notability though. I will re-read the article again sometime soon (probably tomorrow) to see if any additional issues need addressing. Its looking better so far. -- Noj r (talk) 22:44, 3 April 2008 (UTC)
Im going to have to fail this article. The article has more inline citations, but that is not the problem. The problem is the lack of research performed when writing this article. After going through most of the references again I have compiled the following list to give editors an idea of the issues I have:
  • [2] and [3] are completely unreliable. No authors, publishing info, post dates, copyright information.
Y Done*[4] is GameHall, not mega-drive.net, mark that language is in spanish.
Y Done*[9] should have Gamespot cited as the publisher because it is the owner.
  • it's IGN, not Gamespot.
Y Done*[10] should have the author cited, I looked, its right there.
  • [11] has no accessdate, no issue number, and no page numbers. It needs these.
  • [12] is questionable. Author? Publishing info? Post date? What makes this site reliable anyway?
  • [14] is written by Greg Gillis. But who is he?! Why is he notable? Why is this site reliable?
  • [15] and [16] are missing publisher info. These books also appear to be experts on the subject, so why are they not used more?
  • [17] is plain unreliable. No author, no publishing information, no copyrights. Actually there is nothing suggesting reliability on this site.
  • [19] has no copyright information, authors, or anything. Why is it reliable anyway?
Y Done*[20] says the author is Damo, so why is Damien McFerran cited as the author?!

It says Damo on the article page but the full name (Damien "Damo" McFerran) on their About Us page.

  • [22] has no author, post date, publisher. Please use a template. Look at [26] for a good example of proper referencing!
  • [23] same as 23.
  • [24] same as 23.
  • [29] needs an accessdate.
  • [30] How is gameConsole.com reliable? It isnt. There is no copyright, no authors, etc.
  • [32] needs to be cited using a ref template.
  • [34] needs a publisher or a company.
  • [35] should have GamesDog for publisher and not the site link.
  • [36] same as 35. Cite gamespot not uk.gamespot.com
  • [37] use a ref template plz.
  • [38] accessdate?
  • [39] same as 35.
  • [40] Why is this site reliable?
  • [41] same as 35.
  • [44] is unreliable. No copyright info or anything!
  • [46] is unverifiable. Why is this site reliable?!
I stopped after 46. Obviously you understand where I am coming from. The ref section needs to be weeded out and entirely rewritten. Reliable references are needed, and they need to be cited correctly. I probably should have quick failed the article initially, but I felt that a week might be enough time to find reliable references. However, since no significant changes have occurred within the reference section in the past 4 days, there is no way this article could be re-referenced in time and still pass. If you feel this review was unfair in any way, please feel free to have it reassessed. -- Noj r (talk) 00:50, 5 April 2008 (UTC)
A few comments on the above list:
  • [1] Last sentence, last paragraph.
  • [4] Portuguese, not Spanish. .br is a good tipoff.
  • [11] If someone can fill in the rest of [1]this template: {{cite magazine |last=Szczepaniak |first=John |year=2006 |month=July? |title=Retroinspection: Sega Mega Drive |journal=[[Retro Gamer]] |issue=27 |pages=??–?? |publisher=[[Imagine Publishing]] |location=??? |url=http://www.sega-16.com/Retroinspection-%20Mega%20Drive.php |accessdate=2007-11-08}}
  • [16], and maybe [15] (is that from Game Over?), can copy the needed info from SNES#References.
  • [49] Not exactly a wiki, but it's about the same thing. Anyone can post anything there.
  • [59] Ditto.
Anomie⚔ 02:58, 5 April 2008 (UTC)

Other than the fact that I'd call your thinking that WP:SNOW could be applied to three days to weed out reference problems kind of harsh, I'd say fair enough. Red Phoenix (Talk) 17:18, 8 April 2008 (UTC)

[edit] WHY WERENT THEY ABLE TO SECURE LEGAL RIGHTS IN AMERICA?

DID SOMEBODY ELSE TAKE THE NAME FOR ANOTHER PRODUCT? IF SO, WHO AND WHAT?

Sega have never actually said which company it was only that the name was unavailable. There was a company that made a tape drive that was called The Megadrive so that is what people tend to point to, although as I said, people who were at Sega at the time who know the exact details of what happened have never gone public. It would be nice to know the full story one day. - X201 (talk) 19:21, 19 April 2008 (UTC)
This[2] is what a search of the US Trademark office brings up. three different megadrives - X201 (talk) 19:26, 19 April 2008 (UTC)

[edit] Are we ready to try again?

We've weeded out the unreliable references, we've had this article peer reviewed, are we ready for another GA nomination? This article is so close, I don't know what more we can do for it right now. Red Phoenix flame of life...protector of all... 03:06, 20 April 2008 (UTC)

[edit] Reference in Neon Genesis Evangelion

In 23. episode of Neon Genesis Evangelion you can see Asuka playing with a gaming console that is VERY similiar to a Sega Genesis one, and the controller even has "Seca" wrote on it..Should we mention this in this article?195.50.199.47

Not unless you can source it and show how it is notable. Which I don't think it is a notable part. So, I guess I would say no. Red Phoenix flame of life...protector of all... 16:45, 20 April 2008 (UTC)
I'll second that it is not wikt:notable (WP:Notable, of course, doesn't apply here). It's the same as all the crap that was removed from SNES back when we were improving that article. See Wikipedia:VG/GL#Pop culture citations for more details. Anomie⚔ 17:06, 20 April 2008 (UTC)
Agreed. I'm an inclusionist and everything, but there's a line, you know. Red Phoenix flame of life...protector of all... 00:03, 21 April 2008 (UTC)

[edit] GA review 2

  • Well, for one, the technical specifications section doesn't look nice. Try to make it look like the technical specifications section in the wii article.
  • Some of this information is in the Launch section, but there should be a reception section. How many consoles were sold? What did critics think? Pros and Cons?
  • The references are good, but you never have any quotes. Instead of putting it in your own words, try some quotes.
  • I really don't think that it's necessary, there's not really any critical reception statements in the article; nor would there be any today for such an older console. Red Phoenix flame of life...protector of all... 16:02, 23 April 2008 (UTC)
  • Some comparisons between it and other Sega systems. Only the Master Systems is really mentioned.
  • A sequel section, what was the Sega Saturn like? Did it have better critical reception than the Mega Drive? Worse?
  • Y Done The prices of the system should be removed, as different stores sell things for different prices, and so it may not be accurate.

I think that is everything that needs fixing but if anyone sees any other things that need fixes, bring it up here. Epass (talk) 21:39, 22 April 2008 (UTC)

How interesting... I happen to disagree with every one of these points. IMO, the technical information is better done in prose than a list as in Wii, for older consoles reception information is better integrated into the History section, and the rest of the requested information is irrelevant to the topic while the release MSRPs are relevant. If I were to GA review this article, the only issues I see are: the image in Console Wars should be moved (either right-align it or bump it down a paragraph) per the MOS; and in Memory, wasn't the TMSS only in later revisions of the console? There's a bit more needed IMO for an eventual FA push (but still none of the above points), but I'll write that up later. Anomie⚔ 01:33, 23 April 2008 (UTC)
This article has passed all the GA criteria except 3a. The first five things are just suggestions on how to expand, because currently the article doesn't tell 'the major aspects of the topic', there are gaps. And although I think a reception is necessary, if the article has the information without it, it is fine. Epass (talk) 11:09, 23 April 2008 (UTC)
Well, I personally don't think a reception section is necessary given the presence of the Console Wars section. That section covers much of how the Mega Drive sold, though there's no professional reviews. Is it ok if I put Sega Saturn info in the 32-bit section instead of a new section? I don't think there should be too much, given that Sega Saturn has its own article for a reason. I didn't put in the prices, but I'll go ahead and remove them. Also remember there's a major difference between the Wii article and this one in terms of structuring: the Mega Drive era is long gone. The Wii era is anything but gone. Red Phoenix flame of life...protector of all... 15:46, 23 April 2008 (UTC)
IMO, the only mention of the Saturn should involve how (IIRC from Kent's book) Sega decided to drop the Mega Drive in favor of the new console while the Mega Drive still could have had some life left in it. In other words, nothing about the Saturn as such, only about the effect it had on the Mega Drive. Anomie⚔ 17:00, 23 April 2008 (UTC)
Hey, Anomie, can you put that in the 32 bit era and beyond section? As much as I tried, I never found the Kent book. Red Phoenix flame of life...protector of all... 17:06, 23 April 2008 (UTC)
It's checked out from my local library at the moment, unfortunately. I need to try to get a copy one of these days anyway to add references to NES... Anomie⚔ 17:41, 23 April 2008 (UTC)

By the way, I'm going to strike out what I don't think I should do, and I'm going to mark ones that I have done with Y Done. Red Phoenix flame of life...protector of all... 16:02, 23 April 2008 (UTC)

I've performed some significant expansion to the 32 bit era section. How much more work do we need to do? Red Phoenix flame of life...protector of all... 17:00, 24 April 2008 (UTC)

I think a small presentation of the technical specifications with comparisons to its competitors (like the SNES article has) would be appropriate. Zebbe (talk) 22:14, 23 April 2008 (UTC)

I don't know, can you source all of that with reliable sources? If you can, put it in. If not, I'd rather not have it fail for GA because of addition of uncited or poorly cited information. Red Phoenix flame of life...protector of all... 23:49, 23 April 2008 (UTC)

One more thing, there are 4 images right in a row, can some be removed or moved to another part of the article? --Epass (talk) 11:08, 25 April 2008 (UTC)

It has been fixed.Fairfieldfencer FFF 11:29, 25 April 2008 (UTC)

[edit] Pushing for FA

So what's next if we're going to push this article to FA? I've never written an FA before, so I'm not sure exactly what more we need to do (other than add a couple more citations, probably). And thanks for all your kindness everyone, I appreciate the barnstars and the comments you guys have left me. Red Phoenix flame of life...protector of all... 13:47, 28 April 2008 (UTC)

It definitely needs to use the Kent book. Fortunately, my local library had it in when I went there this past weekend, now I just need to find the time to read through the MD-related chapters again and write up some text. Anomie⚔ 03:15, 6 May 2008 (UTC)

After checking WP:FACR. I think the citations are the main thing that there is to worry about. Everything else an FA needs pretty much in place already. We could ask for someone to review it as if it were an FA attempt in order to pre-empt any problems.- X201 (talk) 12:35, 6 May 2008 (UTC)

I want to start by congratulating everyone involved in getting this article up to this standard. It has imrpoved greatly since the last time I looked through it. I have glanced through it and noticed minor problems.
  • Redundancy words have been spotted. e.g “some”, “a variety/number/majority of”, “several”, “a few”, “many”, “any”, “all”.
  • Referencing positioning needs some attention. They should be located right after a punctuation mark.
  • A quick reference check reveals a couple of dead links.

I don't see any dead links, just some moved ones/ ones that were able to be found. Red Phoenix flame of life...protector of all... 02:27, 16 May 2008 (UTC)

As a bit of a progress report, I'm almost done with what I can get from Kent; someone thinks it needs to be "heavily revised" though. There is a good bit on the TMSS and the related court case I have to summarize yet. Anomie⚔ 01:21, 27 May 2008 (UTC)

I think we're a little undersourced in the technical specifications, too. And I'm worried about a couple of sources, since I never got good responses about their reliability (namely the ones you pointed out in your peer review, Anomie.) I'll try to see what I can turn up in my local library, but I'm not hopeful since they didn't even have the Kent book in the whole city (and I live in a fairly large city).

[edit] Corrections and other musings

>>The Sega Mega Drive's CPU is a 16/32-bit Motorola 68000

The 68000 is a 16-bit CPU. It has a 16-bit data bus and 16-bit ALU. Any 32-bit memory access takes two 16-bit accesses back-to-back, 32-bit logic operations require passing data through the ALU in two 16-bit units and the instruction timings reflect this - a true 32-bit CPU would have best-case timings for it's native 32-bit operations, whereas the 68000 has best-case timings for 16-bit operations only.

For comparison the Z80, a well-known 8-bit CPU, can do arithmetic and memory transfers with 16-bit units of data, but again using it's 8-bit data bus and 8-bit ALU twice. It is the same thing with the 68000.

Later versions of the 68000 are 32-bit and the 68000 was designed with a 32-bit upgrade path in mind, but the CPU itself is not 32-bit and should not be labeled as 16/32-bit.

>>"Instead, NTSC games use the 224-line resolution to free up more vertical blanking time to send more updates to the VDP"

This is conjecture. Typically all 240 lines of a NTSC display are not completely visible across your average selection of television sets; for this reason the NES specifications (a console that had a 240-line display) advised important information not to be shown in the upper 8 or lower 8 scanlines, indicating only the middle 224 were guaranteed to be visible. As further proof PAL consoles display more lines per frame, and correspondingly the VDP has a 240-line display mode that only works on PAL consoles. This is a visibility issue, not a performance one.

>>as the extra lines end up in the overscan of a 60 Hz (NTSC) signal.

Incorrect. The 240-line mode does not work on NTSC console at all, the text implies that it could work, but that it would be clipped. The VDP display timing for 240-line mode is hardwired for PAL display characteristics, and selecting 240-line mode on a NTSC console displays an unstable image with no vertical sync or blanking period that rolls repeatedly as the VDP never gets to a high enough scanline number to proceed to generate these signals.

>>The FM sound synthesis IC resembles the Yamaha YM2151

Incorrect. The YM2612 is a derivative of the YM2203 and is functionally identical to two YM2203's in the same physical IC, sans PSG and I/O ports and with some additional features. While the YM2151 is another popular FM chip, it's underlying technology (OPM) is different from that used in the YM2203/YM2612 (OPN). The only similarity the YM2151 and YM2612 have is that they are both FM chips produced by Yamaha.

>>The use of the digitized audio allows for stereo sound and is output only through the headphone jack on model 1 systems and through AV out on model 2 systems along with mono signal.[11]

Misleading. None of the audio output is digital; the PSG in the VDP outputs a single analog channel, the YM2612 outputs two analog channels. All audio mixing and amplification is done with analog electronics.

>>The Secondary RAM, which consists of 8 KB, is part of Z80 address space and is used as Main RAM in Master System compatibility mode. There are also 8 KB of audio RAM.[13]

These two statements are contradictory to earlier information. There is 8K of RAM used by the Z80 which could be described as "Z80 work RAM" which is used for that purpose regardless of Mark-III mode or regular mode. Secondary RAM implies it being secondary to the main RAM of the 68000, though the two are physically isolated on two seperate buses and it's really intended for the Z80. I would suggest deleting the last statement ('there are also...') and calling "Secondary RAM" Z80 work RAM instead.

>>"Majesco's Genesis 3 (single-chip and dual-chip versions) retains the Mode 4 support but has the Master System compatibility removed from the bus controller logic.[13] This renders the Power Base Converter or any other adapter useless. 68000 software can still enable and use Mode 4, however.[11]"

Both statements are not listed on the webpages cited as sources; furthermore I added the original text of these statements (first time they were published publically) to this article quite some time ago. If at one time the webpages had these statements and they were cited then, the authors almost certainly took them from an earlier version of this article. It's a circular reference, and as it stands the citations are incorrect. —Preceding unsigned comment added by 69.110.14.117 (talk) 02:19, 29 May 2008 (UTC)
