SMB on nesDS is better than the GBA version. It's full screen on the DS, and the control feels a bit better.
Anyway, this patch should work for the GBA version: http://www.filefactory.com/file/a136ae/
thnx to that IPS, now i can run the original version too, but i cannot bring the G6's menu which i use for saving, the only thing i could bring, is when i press L and R at same time and it brings a menu which is for game, not G6's, any suggestions?
