i use r4 for my ds. it used to be fine but suddenly i can't use any cheats for my games. when i enable the cheats and start the game its freeze
Maybe that is a sign that you should not use cheats codes in the first place. Seriously, I think that you may have a corrupted cheat database installed on your R4 card. If you re download and install again, you should be able to load the rom without any issues. When in doubt, use google to make sure that the cheat file is placed in the right spot in your microSD card, and be sure that the cheat file you are using is compatible with the R4 card and make sure that you have cheat code usage enabled in the system options. Best of luck, miros
