i have a R4i RTS and everything works fine except for my cheats. i downloaded the latest cheat.dat and put in my _system_ folder but none of the 20 or so games (old and new) that i have on my card have the cheat option available when i highlight them. ive tried leaving it named cheat.dat and renaming it usrcheat.dat but still the same thing. ive had 2 other cards in the past that worked the same way and never had any problems....and from what ive read this one should function no differently. any assistance would be greatly appreciated as im trying to get Phantasy Star Zero playing and from my understanding there is a cheat that allows the game to not white screen after loading it up a second time. im using the latest firmware i can find. the official site is down so i got it from http://www.linfoxdomain.com/nintendo/ds.
