I can't open the CHEAT.dat file on my R4, with the Cheat List Editor. It says something about a format error.
That happens to me too, don't worry about it, just open the editor, put on some game codes with their ids, and save it as usrcheat.dat and put it in your system folder. Tada!
Thanks I've tried your technique! I have both the CHEAT.dat and the one from the Cheat Code Editor in my data folder! 8)
Just curious, does AR host all the cheats for every game, or just certain ones just the the R4 Cheat data file?
