i read about the game Battle of Giants: Mutant insects that not run on this emulator, so i try a new configuration: 1.-run a game with no problems example pokemon platinum. 2.-press f11 for config. options. 3.-change the option start cartrige directly fro NDS BIOS then save options. try run this game and other that have problems, maybe the Sonic racing. I hope this hepl, see ya.
