New version is out, which now supports roms that are above 32MB.
O3DS (still slow, I believe) is now also supported.
CIA is also out, but the 3DSX has better compatibility.
So I just tested Mario Kart Ds with the latest build that works with o3ds :It took some time to launch and lags a lot in the menu and it crash at the character selection. But I would like to thank all the developers that are working on this because It's amazing!
