I'm trying to use cheats on Phantom Hourglass (US), but the codes don't seem to work on this device. I looked at the usrcheat.dat file and the codes match up with what I have on my emulator, where the codes work on the emulator. I can't figure out why they aren't working on the R4i device, though, because all my cheats for the Pokemon games I have work fine, even for the ROM hacks of the Pokemon games. Any ideas what might be going on there?
