I even tried using another Acekard (I have 2 AceKard2i, for backup reasons) update it so that it can be used on a DSi 1.4x firmware and then put in AKAIO 1.5 firmware with it. Next I tested several games with action replay codes (Cheat.dat and usercheat.dat) just incase. I activated it and when I'm in the game, the game acts like no cheat codes is on.
It's definetly the lastest Akaio firmware problem.
Anyone got a work around?
