Can you suggest some good monster raising game you have played? Preferably does that run at least higher then 100% using an emulator.
at the moment there are no nds emulators that run games at full speed, the game will proceed slowly. anyway, the only monster raising games i know are pokemon and digimon. if you want to run these games at full speed then choose one of th following: buy a nds, a r4ds and a microSD card (recommended 2gb) or wait until a good nds emulator comes out.
