File naming clue:
For Android beginners: get a “non-merged” set for your MAME version.
A MAME 0.139 ROM pack (roughly 10GB) running on MAME4droid (0.139u1) is the "Goldilocks zone" for Android. It requires zero tinkering with BIOS files for 90% of classics, runs on a $50 prepaid phone, and the battery drain is minimal.
Skip the 120GB "complete" sets. Curate your own pack of the 50 games you actually played as a kid. Nothing kills nostalgia faster than scrolling through 3,000 mahjong and slot machine ROMs to find X-Men vs. Street Fighter.

Finding a MAME ROM pack for Android requires matching the specific ROM set version to the emulator version you are using, as MAME is highly sensitive to version mismatches. Top Android Emulators & Required ROM Sets
To avoid "missing files" errors, ensure your ROM pack matches these specific versions:
MAME4droid (0.139u1): Requires the 0.139u1 ROM set. This is the most popular choice for Android due to its balance of performance and compatibility.
MAME4droid (0.37b5): Requires the 0.37b5 ROM set. Best for older or lower-spec Android devices as it emulates roughly 2,000 classic titles.
RetroArch (MAME Core): Sideloading the RetroArch APK allows you to use the "Current" MAME core, which works best with up-to-date (0.2xx) ROM sets. Recommended Sources for ROM Packs
