For this 256MB repro you can use the Multimenu ROM Builder tool to create your own compilations.
Please set the jumpers up like this and use a good USB port or mobile phone charger with 1A: ## Savegames

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. 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.
Remember that you will have to patch all roms with eeprom/flashrom save type to sram save using a program like GBA TOOL ADVANCE.
And if your repro does not have a battery you also need to patch the ROM with an batteryless saving patcher.
Lastly for the 256MB repro you can use the Multimenu ROM Builder tool to create your own compilations.
One last interesting detail is that on the MX29GL128E and MSP55LV128 PCB the D0 and D1 pins of the flashrom have been switched around so that the flashrom needs slightly modified flash commands.
