Question is about M3 DS Real with standard firmware. I just downloaded the latest. This is my cheatfile for rom number 5592: Yu-Gi-Oh! World Championship 2011: :BYYJ Code: 521424F0 E3A04012 021424F0 E1A04004 02142518 E1A04004 D2000000 00000000 [End] Basically, I copied the layout of a cheatfile of another game as I knew that one worked perfectly, only with the GameCode of this game, which is BYYJ according to the cheats page, and the code I want for this game. The code has been confirmed (by me) to work (tested it on an emulator. But it's not just this code: no code works for this game), I configured the game to use the cheatfile, the cheat switch is set to "always on"... What am I doing wrong or what is the problem? And how to fix it?
