Many low-powered devices that rely on MAME 0.139 struggle to emulate CHD-based games smoothly due to CPU limitations. Best Practices for Managing Your 0.139 ROMset
To help you with MAME 0.139 ROMset, here are a few general tips:
This core is heavily utilized across various platforms, including: (via RetroPie, Recalbox, or Batocera) Anbernic and Powkiddy handhelds
If you delete the parent game, the clone game will stop working completely.
For users, 0.139 became the default standard for "MAME4droid" (the Android port) and early Raspberry Pi builds (like RetroPie 3.x). Because hardware was slower back then, 0.139 offered the best balance of accuracy and speed.
But why? Isn’t newer always better?
The single-board computer revolution (Pi 2, 3, and 3B+) was built on MAME 0.139. RetroPie, the most popular retro gaming OS, specifically recommended the "lr-mame2003" core for years. The "2003" refers to MAME 0.78, but shortly after, "lr-mame2010" was introduced—which is MAME 0.139. If you have a Pi 3, the 0.139 set runs full speed without frame skipping.
: All clones and regional variants are packed into one ZIP file. This saves space but can be messy. Non-Merged
MAME emulators are designed to read the contents of compressed .zip or .7z archives directly. Unzipping them will cause the emulator to fail to recognize the games.
MAME 0.139 supports CHDs, but very few arcade games required them at that time. Notable exceptions:
Every single zip file contains 100% of the files needed to run that specific game.
