Trauma center - Works pretty damn well, no saving though
Advance wars DS - Works near perfect, only a few gfx glitches
There's plenty others working, but i've been testing on different emus, so i don't remember if they worked on No$GBA or if i'm confusing them with some other emu.
I highly recommend the latest build of iDeaS. The 3D is working great, only needs a major cleanup, but it's very stable and highly compatible. I've been playing Trauma center on it for a whyle, works great, and despite not being able to save in-game, there's a good and working save state funcion.
The next build of DeSmume is looking very promising as well, look out for version 0.7.1 when it comes out, i think it'll top both No$GBA and iDeaS after that.
All work and no play makes me..., well, you know the rest.
