Google is your friend. I googled some of the chips, and here's what I found:
- Flash chip with builtin RAM. This is one is unsuitable for use with a GB(C) since it uses 3.3 V rather than 5 V. You could use a voltage regulator, but all in all I don't think it will be worth the effort for you. This chip coul perhaps be used with a GBA, but it would take some engineering.
The other chips that I see on this picture are other things. (Not memory)
- A microcontroller and some other form of controller chip. Nothing useful for a GB flash cart.
1 MHz clock oscillator
- Just as you noticed. Nothing really remarkable about it.
- This is an OTPROM, which stands for One Time Programmable Read Only Memory. Already filled with something, thus no use for anything for you. Btw, Atmel, not Amtel.
- I recognize this as a PokÃ©mon blue or red cart. Which means it might not be GBC double-speed compatible. The MBC3 (Memory mapper) on that cart should be ble to address however big the PokÃ©mon ROM is. (256 or 512 kBytes if I remember it correctly)
If you have a voltmeter you should be able to check the battery status. It should somewhere between 2.7-3.1 V. But that should not prevent the game from booting already at the Nintendo logo stage. At a stretch it might make the game crash after the logo, but probably it would just work without being able to save a game, if it was a battery problem.
Out of curiosity, can you post a picture of the glitched logo? Or at least tell me how it was glitched? (Completely garbled? You could see traces of the logo? Regular pattern of white or black pixels?) If you're going to take a picture, use the macro mode of your camera!
edit: just realised something........gb games have mappers I think (at least some of them) this cart would only work for games with THAT mapper thats inside the cart. (I think they had a pretty standard one on gameboy though that most games used)
Not much of a problem. Most GB mappers are interoperable, except for size limitations. The notable exception is MBC1 based carts using big ROM sizes, but it's not a real problem. If you'd really find such a game, you could probably patch it anyway.
You're probably thinking about NES, which suffers from a real mapper hell.
