TGEmu/MacOS is a PC Engine emulator for the Macintosh.
TGEmu features reasonably good compatibility with PC Engine HuCards. While this release does not support CD-ROM based software, this will be included in a future release. Sound emulation is supported, though it is nowhere near perfect just yet. Sprite priority emulation is supported as an option for the games that need it. Also, the emulator can use Gzip compressed ROMs transparently.
• Mach-O conversion, as well as lots of bug fixes and improvements. For full list, see here.
