byuu says: Changelog: - int_t<bits> replaced with Integer<bits> - uint_t<bits> replaced with Natural<bits> - fixed "Synchronize Audio" menu option that broke recently - all of sfc/performance ported to "auto function() -> return;" syntax With this WIP, all of higan is finally ported over to the new function declaration syntax. Thank the gods. There's still going to be periodic disruption for diffs from porting over signed->int, unsigned->uint, and whatever we come up with for the new Natural<> and Integer<> classes. But the worst of it's behind us now.
