3.4 Packaging into IPA

Archive the build in Xcode and export as an IPA.
Verify IPA contents (Payload/.app, iTunesMetadata.plist optional, META-INF absent).

Legal & Ethical Considerations

Emulators themselves are legal in most jurisdictions. However, downloading ROMs for games you do not own is copyright infringement. The recommended approach is to dump your own arcade PCBs or use only public-domain/abandonware titles. Mame4ios does not include any ROMs; users must provide their own.

Steps to add ROMs:

Connect your iPhone to a PC and open iTunes (or Finder on Mac).
Select "File Sharing."
Look for the Mame4iOS app in the list.
Drag and drop your .zip ROM files into the Documents or ROMs folder.
Do not unzip the files—MAME requires the ROMs to stay compressed.
Refresh the game list inside Mame4iOS.

Final Thoughts

Mame4ios remains a beloved tool for arcade purists who want to carry Teenage Mutant Ninja Turtles or Final Fight in their pocket. Its IPA distribution model keeps it alive outside Apple’s walled garden, but at the cost of installation friction and expiration headaches.

If you’re willing to refresh a sideloaded app weekly, Mame4ios is a fantastic way to preserve arcade history. For a smoother experience, consider a device-hopping approach: keep an older iPad on a compatible iOS version, or switch to Android where emulation is one-click install.
