gba eeprom

[stuntpenguin007]

Does anybody have any specs on gba eeprom's? I know that all games probably have lightly differant eeproms but what kind of eeprom programmer would one need to program an eeprom for a gba game? I'm kind of hoping the eeprom is that little 8 pin chip, because I wouldn't want to solder much more than that. Basically I want to try put a gameboy color game on a gba cart, but If that doesn't work I'd still be interested In an eeprom programmer for gba use.

Those 8 pin (or less) EEPROM's you're talking about are called serial EEPROM's and for GBA games, they usually they hold save data. (Replacing battery packed RAM) On the other hand Flash memory is usually used for holding the ROM image(s).
The Flash chip has a lot more legs than the serial EEPROM and needs to have that in order to be connected to the system BUS of the GBA. However, the GBA fetches data from the cartridge in a "strange" because the cartridge bus has the same physical layout as that of older GB models. (And thus a limited number of pins) In detail it sends out the address to be read in two pieces.
Therefore you need either a special controller chip which can latch the first part of the address, or possibly an especially designed Flash chip.

As for your desire to run a GBC game on a GBA cart, have you checked out the "GB Bridge" thingie?
