plays fine on 1.0.2 ds-x with no arm7 fix, no saving. Did a quick arm7 patch, loads up fine until I'm about to play, then stays on a black screen. Gonna try a couple different things and see what I can get...
Also, while I played the game before the patch, it was decent, but I can see how this game would get pretty boring pretty quick. The balls don't move on a little track, they move around little villages, but might as well be on a track. Pretty basic gameplay, but I hadn't played any of the other variations, so no idea how this compares...
