More modern look coming this fall.
iMAME Arcade Emulator Hits the App Store (For Now) [Update: Pulled]
iMAME running Simpsons with iCade support.
iMAME ships with nine "less than stellar" ROMs to play, but apparently can load arbitrary ROMs using a 3rd party utility such as iExplorer without jailbreaking:
It seems that the same method used to get games into iDOS also works in iMAME. Twitter user @mattlukens mentions, "Yep, add a .zip rom to the Docs folder through PhoneView and it works perfect! Just tried Crime Fighters!" He also provided a screenshot. The clock is really ticking now on Apple pulling this downApple has had a bit of a spotty history with emulators on the App Store. While a number of individual emulators do exist on the App Store, Apple has been more restrictive about these open emulators, presumably due to potential legal issues. For example, a full DOS/Windows 3.0 emulator appeared in the App Store at one point but was quickly pulled by Apple.
iMAME is currently available as a free Universal application on the App Store. [Link]
Update: It took Apple two days to get around to it with the holidays, but iMAME has been removed from the App Store.
