I've made a proper Universal build of ScummVM; it's compiled identically to the mainline packages (i.e. Vorbis, MPEG2, FLAC, etc.) and is native on both platforms.
It's tested and working fine as far as I can tell, and the only changes I made were for endianness (due to assumptions about PPC) and disabling NASM in both FLAC and ScummVM.
Despite the disabled ASM stuff, it is pretty darn fast on my MacBook

I'm wondering what I should do with it now; would the maintainers like to host it or would you just want the patches?
