RetroArch

RetroArch is a very special emulator. Instead of focusing on a single console, it covers all kinds of consoles to emulate thousands of games on various platforms with the help of some of the most popular emulators for each platform. With this program, you can transform your Mac into a true gaming machine.

RetroArch's surprisingly comprehensive list of consoles (with the emulator in parentheses) includes PlayStation 1 (PCSX ReARMed), Super Nintendo (SNES9x Next), Nintendo Entertainment System (FCEUmm / NEStopia), GameBoy / GameBoy Color (Gambatte), GameBoy Advance (VBA Next), Arcade (Final Burn Alpha), Neo Geo Pocket Color (Mednafen NGP), Virtual Boy (Mednafen VB), Sega Genesis / Mega Drive (Genesis Plus GX), Sega Master System / Sega Game Gear (Genesis Plus GX), Sega CD / Mega CD (Genesis Plus GX), PC Engine / PC Engine CD (Mednafen PCE Fast), WonderSwan Color / Crystal (Mednafen Wonderswan), and more.

As if that weren't enough, RetroArch Android also perfectly emulates Doom 1, Doom 2, Ultimate Doom, and Final Doom. As we all know, every emulator worth its salt has to include Doom. That said, RetroArch doesn't come with any video game ROMs. The emulators come in the Libreto folder or with their own installer included within the program, but the ROMs have to be downloaded separately from another website.

RetroArch is by far the most comprehensive compendium of emulators out there. Other emulators are good for one or two consoles, but with RetroArch, you can emulate literally thousands of games.
