Ph0x sent me over a few patches to his backend today to get unstable 0.5.1 ScummVM support. Considering I have moved away from SDL back to a custom backend I am going to merge big parts of this into my code and continue with the part SDL/part GP32 SDK backend.

Also, I now have a very odd bug that means I can't link MP3 and OGG libraries into the same executable without it crashing :(.
