I just got my AceKard 2i and I am running it on the DSi. I tried using cheat.dat, cheat.xml, usrcheat.dat, and cheat.db but nothing works. I am running on firmware 4.16. I also tried using AKAIO, but I must have done something wrong. I could see the cheats, but when I tried to load any game, it would get stuck on the loading screen. Any ideas to help me fix either one of these problems? Thanks.
