Because the 0.139u1 set is static, it does not include fixes implemented in later MAME versions. If a specific game had an audio bug in 2010, that bug persists in the Android port today. Users downloading "Pack Roms" often treat these files as black boxes, unaware that specific games may run imperfectly compared to modern emulation standards.
This paper examines the specific version MAME4droid 0.139u1, an emulator that ports the Multiple Arcade Machine Emulator (MAME) to the Android platform. It focuses on the technical specifications of this version, the concept of “Pack ROMs” (collections of game dumps), and the associated legal and preservationist debates. While advocating for the legitimate use of emulation in digital preservation, the paper addresses the legal gray areas and technical challenges unique to this outdated but influential emulation snapshot.
MAME4droid 0.139u1 and its associated Pack ROMs represent a specific historical moment in mobile emulation—prioritizing accessibility on weak hardware over emulation accuracy. However, from a modern perspective, reliance on these outdated packs perpetuates legal risk and technical limitations. Legitimate users and preservers should migrate to newer MAME versions and either dump their own ROMs or use legally licensed compilations. Pack Roms Mame4droid 0.139u1

A proper MAME set is not just a folder of random .zip files. It is a curated, complete collection of every arcade game dumped as of that version. A full 0.139 set is approximately 35-40 GB uncompressed (around 25-30 GB compressed).
A "pack" usually refers to either:
For MAME4droid, a Non-Merged set is the most user-friendly because you can copy individual game .zip files without worrying about missing parent ROMs.
Before loading a game, ensure your BIOS files are in the roms folder. Place neogeo.zip in the folder. Without it, no Neo Geo game (Metal Slug, King of Fighters) will work. Restart the app to load the BIOS. References
