Whenever I patch my GBA games with the cheat patches on the M3 Game Manager, load the game, and select the codes I want, none of the codes seem to work. I have tried multiple games, and none of them seem to work and the game goes on like normally. What could be wrong? Also, whenever I try to convert a txt file to a dat file (so that I can make a cht file), the converter locks up. This will mean that I can't make my own codes. Is there anything I can do to fix this?
