i tried a while ago warpscummvm with warpsdl.library and that one flies on me 4000 setup with cybergraphx only the development has stopped , maybe that you can improve that one to the newest scummvm, if its not to much work and you can get the source codes.
but on the other hand i hope that the whole development on scummvm rtg does continue its great to see scummvm working again the right way.
again big thanks to you Nova Coder
