I recently discovered that i can replace my gba 369in1 cartridge's games by using GBABF tool on the ds lite to flash other games instead those listed in the cartridge's menu. The included games initialy can save batteryless, but the major problem is that when you flash a new game on this bootleg, it can't save. I couldn't identify the save type of the cartridge and i can't save during playing the games i flashed on it. Can someone help me to find out how to modify gba roms like Castlevania, metroid and pokemon so they can save progress ? Or, is there a place where i can find these games already patched for this kind of batteryless bootleg ?
