I'm working on getting everything ported to build my Sonic hack on my android phone while running GNUROOT Debian. But here is where I think I'm having trouble. asl needs to be built for arm64 in order for the build tool to run. I know where to get the source, as stated in the notes file in build_sources. But I'm not sure which .C file is the main one that I need to build with GCC. Can anybody point me in the right direction?
