I searched the forum and couldn't find a solution to my problem so I'm posting it here. I have the English Pokemon Black rom. I'm using the R4i-sdhc cart. I got the rom to run properly on my DS using TTMenu. The problem is that if I enable cheats, and attempt to use AR codes, I can still play the game, but am unable to save. It simply freezes during the saving process. Without the codes, it saves fine. Any help at all would be wonderful, thanks!
