Hi, As seen in my previous posts, I'm now the owner of a AK 2.1 (at least 2.1 is printed on the label, Pictures can be found here) and I have some problemes with this card regarding the cheat functions. I'm usually no user of cheats, but I use the Backlight code in many games on my old M3 DS Simply and they are working great. On my AK I installed the latest 4.08 FW and the cheats.xml (EU only) from cheats.gbatemp.net. I Fired it up and rebuilded the cheat database and enabled the backlight codes e.g. for N+. Then I enabled cheats in the global settings and tried to launch the game. The loader said "Loading" and after this the white screen appeared. If tried serveral games and serveral cheats and it's allways the same result. If I enabled the cheat engine all games with enabled cheats will launch with a white screen. Is my AK just faulty or is this a known problem? I have also tried the AKAIO FW but theres the same problem.
