I try to port ScummVM to AROS. But don't count on it too much because I'm probably trying something I'm not cabaple of.
I try to do the following:
-Port the MorphOS-Version to Amiga. The newest Amigaversion uses WarpUP so it's probably easier to adjust the Morphosversion (That's at least what the author said).
-Recompile the Programm for AROS. It doesn't use any special components so it should work without big problems
I don't think it's a good idea to change uio.h just to io.h because they've neither done that in the Amiga Version nor the Morphos-Version
