byuu says:

Changelog:
- fixed icarus to save settings properly
- fixed higan's full screen toggle on OS X
- increased "Add Codes" button width to avoid text clipping
- implemented cocoa/canvas.cpp
- added 1s delay after mapping inputs before re-enabling the window
  (wasn't actually necessary, but already added it)
- fixed setEnabled(false) on Cocoa's ListView and TextEdit widgets
- updated nall::programpath() to use GetModuleFileName on Windows
- GB: system uses open collector logic, so unmapped reads return 0xFF,
  not 0x00 (passes blargg's cpu_instrs again) [gekkio]
