This is a 100% game save for Super Mario Advance with all levels beaten, all coins collected, all yoshi eggs collected, red yoshi on title screen and max score for both game remakes. File 1 is the 100% save and file 2 is new game.
Yeah it works great but it's the obvious Ds factor you loose from it it's not like playing atari games on atari because Nintendo actually use to give a reason to buy their hardware
I just like game consoles how they were intended to play if they have a unique enough reason to buy them anything else yeah just download emulation for it
