No$gba v2.3 contains almost full NDS emulation support including 3D. For a list of missing features and known problems, see here.

CAUTION:
The shareware & commecial versions include debugging features which are
useful for programmers ONLY, these versions are COMPLETELY USELESS for
gamers. That means, if you are a gamer, then you do NOT need to buy (or
steal) anything, you already GOT EVERYTHING you need FOR FREE.
