byuu says: Changelog: - restructured the project and removed a whole bunch of old/dead directives from higan/GNUmakefile - huge amounts of work on hiro/cocoa (compiles but ~70% of the functionality is commented out) - fixed a masking error in my ARM CPU disassembler [Lioncash] - SFC: decided to change board cic=(411,413) back to board region=(ntsc,pal) ... the former was too obtuse If you rename Boolean (it's a problem with an include from ruby, not from hiro) and disable all the ruby drivers, you can compile an OS X binary, but obviously it's not going to do anything. It's a boring WIP, I just wanted to push out the project structure change now at the start of this WIP cycle.
