Apple has never shown favor to emulators in its App Store (with the exception of examples like the Commodore 64 app), so it’s surprising to see iMAME available in the App Store for free right now. iMAME allows you to run thousands of classic arcade titles if you’re lucky enough to have the original ROMs.
The emulator app includes 9 less-than-popular arcade games to run, but the possibilities are pretty endless if you know what you’re doing.
It seems that you can sideload a ROM .zip file to iMAME with a tool like iExplorer. No jailbreak is required. Mario on the iPhone, anyone?
Apple’s review team has let several questionable apps into the App Store as of late (iTether and QuickPick, for example). It will be interesting to see if these types of Apple Store slips continue to become more frequent.
So, what are you waiting for? Get iMAME before it’s gone!
