I recently got an ez flash omega. I put on the software and it is able to detect that the roms are there, it can play the gameboy and gameboy colour roms fine. The problem arises when I try to play the gameboy advanced games. The games will either not load at all and show a frozen screen or play for a minute or two and then freeze. I'm not sure what the problem is since it plays the other gameboy games fine. One thing to note is the gameboy needs a new battery and won't operate unless constantly plugged in. I have formatted the micro sd to fat 32, the memory I'm using is sandisk ultra 32 gb, I have updated the kernel to the most recent for the omega. I can't find out what's wrong with it. The only thing I can think of is either the cartridge is faulty, the micro sd memory is bad or the contacts between the gba and the cartridge are dirty. I have a copy of donkey kong country 3 and it works fine as well. I truly don't know what's wrong with the ez flash cartridge. Any help is greatly appreciated.
