Solution: Go to Settings inside Mame4iOS and toggle "Sample Rate" to 44100Hz. Also, ensure your ringer switch is not on silent.
If you have a Mac, you can use Xcode to build the app from the project file ( MAME4iOS.xcodeproj ) and install it directly to your device.
The application is typically distributed as an .ipa file, which must be sideloaded since it is not hosted on the official App Store.
Mame4iOS is a functional, no-frills arcade emulator that works well on sideloaded or jailbroken iOS devices. Its performance is solid for 2D classics but struggles with later 90s titles. Given its age and lack of updates, or RetroArch are generally better choices today—unless you specifically want a lightweight, single-purpose MAME IPA with minimal setup overhead.
