Reflashing GBA repros
In the "Flash Repro" sub-menu under "Game Boy" you will find the following options:
- GBA Repro (3V)
- GBA 369-in-1 (3V)
Currently the cart reader supports three types of GBA repro pcbs...
Intel 4000L0YBQ0 (32MB)
Macronix MX29GL128E (16MB)
Fujitsu MSP55LV128 (16MB)
...and one multi game cartridge.
Intel F0088H0 (256MB)
For this 256MB repro you can use the Multimenu ROM Builder tool to create your own compilations.
Repros with SRAM and a battery only support SRAM saves therefore you will have to patch all ROMS with eeprom/flashrom save type to SRAM save using a program like GBA TOOL ADVANCE.
Repros that come without a battery have the save located inside the ROM area. When booting the game there is a routine hacked into the ROM that copies the save from the flashrom into the SRAM. When you save in-game the save gets copied back into the flashrom.
ROMs flashed to those in addition need to go through a batteryless saving patcher.
