[edit] PlayStation on 1995?

Sorry but I've always thought that the playstation was released on 1996. Well maybe 10 years has make deep holes in my mind


The Japan ps1 came out in 1994, USA 1995. That's why we missed out on a few launch titles from Japan, for instance the true King'sField1 came in Japan in 1994 and the sequal was a launched title here. I played the very first J one too, it's swifter, though actually the others suffered from slowdown without frame skip as can be seen in KF1USA.

KF2USA is in reality at a constant slowdown state almost due to about ps2 resolution or scaled textures and not enough fillrate out of their engine for them at that framerate.BobtheVila

[edit] Picture of Playstation Prototype (Nintendo)

Please insert this picture. Prototype of Playstation (Nitendo). http://www.bilder-hosting.de/show/WLVZ6.html —Preceding unsigned comment added by 80.146.97.104 (talk) 19:14, 31 August 2007 (UTC)

[edit] Last German release

I corrected the last German release which was "7 Shoot Games" by Phoenix/Naps in 2005. "Schnappi" came out months before. TraunStaa 21:38, 6 September 2007 (UTC)

[edit] My PS1 Knowledge

The Playstation was considered more successful than the Nintendo 64. The Playstation was sold from 1995-2006 and Sold over 100,000,000 units. I have a Playstation 1 that is 8 years old. User:CDHgrün 15-9-07 —Preceding signed but undated comment was added at 11:50, 16 September 2007 (UTC)


[edit] price wrong

Playstation scph 1001 going for $50 and sounding like a $6000 audio system. Pezno1 13:52, 25 September 2007 (UTC)

Early PlayStations used high quality Ashahi Kasei Microsystems (AKM) DACs that are commonly used in high end expensive equipment. It is true that an SCPH-3000, SCPH-1001, and SCPH-1002 make for a very good CD player for the price. The SCPH-5000 series also uses this DAC. The early SCPH-1000 used a slightly older version of the DAC and the SCPH-7000 series used a lesser quality cost reduced version. Eventually the AKM DAC was replaced with low cost alternatives from other manufacturers to further reduce the systems cost. A lot of people are assuming any statements about this are saying the old PlayStations sell for $6000 (especially in regard to a certain video posted on YouTube. I'm not even going to go into the stupidity of showing high quality audio on YouTube in the first place) and this is just insane. They sell for $50 or less in most cases. I know these people know better. Personally I just think it eats many people alive to acknowledge something with the SONY name on it could be high quality. They will of course ignore this when you talk about the high quality SONY designed audio hardware used in the SNES. The irony in this is SONY does not even make the DACs in question.

[edit] Old demo desk

I used to have a demo disk and I was wondering if anyone remembers it. I remember it had parappa the rappa, a Tekken-like game, a game named Cliffhanger or something (you used a grappling hook) and some other games. Anyone remember this?

Yes, I know what your talking about. I remember that it came prepackaged with the system when I bought it. It has a hockey demo,crash bandicoot, WWF and other games. Patrolman89 (talk) 02:28, 5 January 2008 (UTC)

[edit] Story

I placed a banner on the article stating that the present article text "is written in an informal style and with a personally invested tone" that is not consistent with a neutral point of view. In addition to the many uses of editorializing phrasings, statements such as "Yamauchi was furious", "a complete shock" "absolutely unthinkable" are not encyclopedic in tone.

[edit] Graphics API

Which graphics was used? OpenGL or some some sort of proprietary API? Or even Assembler? —Preceding unsigned comment added by 81.209.204.207 (talk) 14:41, 29 November 2007 (UTC)

[edit] Regarding Debuggers and Yarozes

  • All green debuggers and Yarozes use the same old lasers as the blue debuggers. Only blue models are listed as having a "low quality laser" in the specialty models section however.
  • Unlike what the special models section states, the green debuggers cannot play discs from "every region". They cannot switch video modes (the video simply blacks out completely if a switch is attempted) so a NTSC green unit will only play NTSC games (both U/C and J) and a PAL green unit will only play PAL games. —Preceding unsigned comment added by 91.154.56.117 (talk) 08:05, 30 November 2007 (UTC)
Feel free to correct the list if you have information. Thats how Wikipedia works :). I compiled it and am the first to admit the notes are probably not entirely accurate. I created the list hoping to draw attention and help cleaning it up. The whole damn PlayStation page itself needs major work. In some ways I think the model list might be causing more harm then good as it is kind of cluttered. Perhaps the whole list should be revised or even scrapped. The bulk of the model number and BIOS information is taken from the MESS emulator "psx.c" (current list updated to MESS 0.121) source code file as well as model numbers and BIOS dumps from my own personal PlayStation console collection. I think this information is accurate and as complete as it can be for now. I was not sure what laser the green systems use so I did not make a note of it. If you know what laser it uses feel free to add it. I would like to add the actuall model numbers for the lasers instead of just stating "low" or "high" quality. KSM-440ACM, KSM-440ADM, KSM-440AEM, and KSM-440BAM are the four models I am aware of. This might be an imposable task though. I would also like to add information about the DSP used (at least 4 exist) but this again might be an imposable task. I believe a blue NTSC system will play PAL games but the image is offset as should be expected. I highly doubt it would work on a PAL TV as the video mode itself is locked to NTSC. This would mean statements that it can play all region games are still accurate despite not being the best idea in the world. If you have knowledge to the contrary then correct the list. Other information that potentially needs addressing is the CPU/GPU silicon revisions and exactly what model relocated the CD-ROM drive. Generalleoff (talk) 07:51, 24 December 2007 (UTC)

GameTrailers' Bonus Round Episode 17: Part 2 of 4.--Svetovid (talk) 20:12, 17 December 2007 (UTC)

[edit] Reference [7] is incorrect

It's referenced to prove PSOne 100M sales, but the pdf is actually about PS2 hitting 100 million in 2005 —Preceding unsigned comment added by 89.112.31.162 (talk) 22:55, 13 January 2008 (UTC)

[edit] About ps1 geometry

Could it be with Vu0 and Vu1 that it's 1.5-500k T/sec? Maybe the calculater only did it with one. 180k give only 6k a frame at 30fps. I'm pretty sure some games like Apocolypes or other done slightly higher.

Actually I've heard not 500k but 360,000 textured. If so it would be 360,000/sec and 12k at 30fps. Someone should look into it.BobtheVila


I did some calc though with Apocolypes...15 150 poly charas is 2,250 and that leaves around 3,000 polys. Still some other games may produce alittle more, or not. So i'm not changing anything.BobtheVila

[edit] What date in November 1995 was the PS1 released in Australasia?

I don't really think that we should have just November 1995 as a date when the PS1 was released in Australasia. We need the exact date when it was released. Anyone in the PlayStation Project should do it; find out the exact date when the PS1 was released.124.181.224.121 (talk) 05:15, 27 January 2008 (UTC)

[edit] 32-bit

It is 16 to 64 bit. 76.126.29.36 (talk) 23:35, 27 February 2008 (UTC)

[edit] Black discs? Infrared laser? wrong.

The discs weren't black, they're very dark blue. Also, the laser sensor isn't infrared, it's a normal 780nM laser diode like any CD player. Someone please fix this... I'm no good with corrections. —Preceding unsigned comment added by 71.114.172.234 (talk) 00:56, 26 March 2008 (UTC)

[edit] contested statement removed

  • A common, but temporary, fix to the laser problem was to tip the PlayStation on its side. This made the tray "hang" perpendicular to the CD, allowing the PlayStation to read the disc. Unfortunately, friction would continue to wear down the plastic tray and, eventually, the PlayStation would not read the disc. {{Fact|date=December 2006}}

Please do not return this information to the article without a citation.--BirgitteSB 15:08, 6 June 2008 (UTC)

I don't have a reliable source but I can confirm this. Years ago a friend insisted his PlayStation only worked upside-down, and to this day I didn't believe it, but I guess it wasn't uncommon. Unfortunately I guess that would be "original research." 66.189.65.178 (talk) 03:56, 7 June 2008 (UTC)
