I have tried every possible way of adding cheats to my R4, I have the programme to open the CHEAT.DAT file and edited that, have tried downloading the CHEAT.DAT files. I tried the urscheat file. I have deleted the menu system file that didn't work. I have moved the file around on the card. I have edited the id of the game. At first it said there were no cheats avaliable but now it brings up "cheat db file is invalid". I'm at my wits end and very frustrated! Can someone give me a step by step instruction on how I get cheats onto my R4 that work?
