sprite sizes

[angor]

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

If it has the same 2D engine that GBA all the sizes that support are:

8x8,  16x16, 32x32, 64x64
8x16, 8x32,  16x32, 32x64
16x8, 32x8,  32x16, 64x32

Maybe more, but I think that these is all.
