Ok, i got a r4iiisdhc r4 clone. it works flawlessly, exept when enabling cheats, when i do that, and i try to load a game it just freezes(didn't do this with all games. cheats from mario kart where enabled before without problems.) but most of my games, after anabling cheats in the cheat menu, after that all games freeze until i do a format of the sd card. then eveything work until i enable another cheat.(or when i put some files on the sd that don't belong there, like some mp3's) so after this, disabling the cheat, or puting the original firmware+files on the sdcard(overwrite over the old one) does nothing. it still hangs when loading a game, so assuming that after i put the original firmware back on the card(including the original configuration files) the card is" exept for the roms that are on the sd card" a clean install of the firmware(if we can call it a install by just copieing over the files) until i format then it works again. stranges thing is, while every game freezes at the r4 loading screen after this, the emulators will run. this happend to me multiple times. i had it before when my snesmulds created a sav file for super mario world, after that no game would boot(exept the emu's) so i'm figuring that when some files changes on the sd card, no game will boot anymore untill i do a format of the sd card. anyone know whats going on? is it my sd card or is it the clone?
