I fixed the decoding, I wonder if this codec has to flipped or if this is only necessary because you encoded with VirtualDub.

Replying to cehoyos:

The problem with flipped output happens only with RGBA mode, so if there is no other RGBA loco sample which decodes correctly I think it would be good to flip RGBA output.
