I have a Gold R4 3DS. Some of the roms works fine but others don't . Mario cart, nintendogs, and some other japanese rom works. But I cant get New Super Mario, Kirby Canvas Curse, Pokemon series, and some other roms to finish loading. Those works fine on my TTDS. Why cant I get them to work on my R4? The game icon and the cheat browser comes out fine for each game and all, but it just wont finish loading and freezes in middle of loading process. Are there any possible solution for this? Pleas tel me.
