The emulator itself is 100% legal. It is open-source code that recreates hardware behavior. The legal risk comes from downloading copyrighted ROMs. Many retro gamers ignore this because the original arcade hardware is no longer in production, but companies like Nintendo and Capcom still hold intellectual property rights.
Our advice: Own the original game. If you have a Street Fighter II arcade board collecting dust, you have the moral and legal right to dump and emulate it on your iPhone.

MAME4iOS (Multiple Arcade Machine Emulator for iOS) is an open-source port of the legendary MAME project, designed to emulate thousands of vintage arcade systems and classic computers on Apple mobile devices. Distributed as an IPA file, it allows users to experience decades of gaming history—from the 1970s through the early 2000s—on their iPhone, iPad, and Apple TV. Core Versions & ROM Compatibility
Because arcade hardware evolved rapidly, MAME4iOS is often divided into specific builds to balance performance with game compatibility.
MAME4iOS (Modern): Typically based on MAME core 0.238 or later, this version targets newer 64-bit devices like those with M1/M2 chips. It supports roughly 5,000–8,000+ romsets depending on the specific build.
MAME4iOS (Classic/Reloaded): Often based on the 0.139u1 romset (circa 2010), this version is optimized for older or less powerful hardware while maintaining broad compatibility for 2D arcade classics.
ArcadeMania: A version of MAME4iOS that was successfully submitted to the official Apple App Store in late 2024/early 2025, providing an easier installation route for users. Key Technical Features

Because "proper feature" is a bit ambiguous, I have broken this down into the key features that make MAME4iOS distinct, and the proper way to use the .ipa file.
The golden age of arcade gaming—titles like Pac-Man, Street Fighter II, The Simpsons, and 1942—never truly dies. Thanks to the Multi Arcade Machine Emulator (MAME), these classics have been preserved for modern hardware. For iOS users, one of the most enduring names in this space is Mame4ios. But with Apple’s strict App Store policies, the emulator exists in a gray area, distributed primarily as an IPA file. Here’s everything you need to know.
Cause: The IPA was built for an older iOS version or the signature is corrupt. Solution: Download a fresh Mame4iOS IPA from a trusted source. Ensure it is compiled for arm64 (iOS 11+).
