hi guys, i really need some help here! so this is basically what happened.... i used to have an awsome ds and games and stuff but one day i decided to try YSmenu. i followed the guide and everything but it wouldnt work i gave up after hours of trying to get it to work. i looked for my old firmware but i relised to late that i had deleted it i found new firmware that is compatible with my R4 (SDHC Revolution) i got firmware from this website http://www.r4sdhc.com/download-en.htm all my games worked and i was happy. i wanted to get some cheats for my games though (i deleted - by accident - my old urscheat file) so i did all the stuff with cheat code editor and got the cheats on my ds. i try/ed to play pokemon platinum but it just goes to white screen so i disable the cheats and it sttill wont work. i have redone (ie) reput firmware on, put game on again and redo cheats but it still wont work when the urscheat file is on my ds. im very sad cause i really want to play pokemon (again) with cheats can anyone give me an explanation as to why this happens? looking forward to peoples theories. HELP!
