Since i am not quite familiar with the DS hardware my question's answer is maybe is obvious. Any case, I am wondering which sprite sizes are permited in DS (and then in DS LUA). I have used 8x8, 32x32 and 64x64 successfully, but the system crashed when i tried to use 32x64...

a) is any size combination allowed [width] x [height]? (i am afraid not...)
b) if only a few combinations are allowed, which ones?

Thanks in adavance
Angor
