[edit] Technical notes
- No resume from automatic shutdown? (requires switching off and on)
- Buttons do not use inverted logic levels.
- There are some testpads that might be useful.
- No clue yet if there's a write signal, which would be handy for in-system flashing and I/O port)
- Volume buttons are wired to the main chip.
- At least one trace from the main glob chip goes to a second glob chip. Perhaps that's an amplifier.
- With a solder bridge, the mode can be changed from NTSC to PAL if neccesary.
- Two TSOP-48 (flash?)ROM chips. Each ROM is probably 1Mx16 = 2 MBytes which would give a total of 4 MBytes.
They are painted black to prevent identification. One of the chips reveals the text "64MB2" in lower-right corner. They are wired in parallel and a simple 74HC00 controls the Output-Enable signals for them. Pinout might be something like [[1]]. After disabling the second chip, nothing appears different until some games are started. When it tries to load the graphics, it reads random data.
