I've recently restarted playing Pokemon games for GBA because of gpSPhone for iPhones. The cheat code function on gpSPhone is pretty crappy since not all codes works on it, so I resorted to using No$Gba to use the cheats and transfer the save file to gpSPhone. The only cheats that seem to work are Codebreaker codes which are listed as Gameshark codes. When I input AR codes, a "?" mark appears and nothing happens. The same codes work on VBA but the game wouldn't save on VBA so I'm back on using NO$GBA. Is it a problem with the emulator?
