  1. Last version before major changes – Shortly after 0.139, MAME underwent a significant internal rewrite (new core, changed ROM naming/requirements). Many games that worked in 0.139 broke in later versions without updated ROMs.
  2. Final support for older ROM naming conventions – Later MAME versions require “merged sets” and verified CHD (Compressed Hard Disk) files for many games. v0.139 has fewer CHD requirements.
  3. Smaller total size – A full v0.139 ROM set (without CHDs) is roughly 25–30 GB. Including CHDs (for games like Killer Instinct, NBA Jam, etc.) it can reach 150+ GB, but that’s still smaller than modern full sets (500+ GB).
  4. Compatibility with lightweight frontends – Many retro handhelds and older PCs run v0.139 easily.

Compatibility: It avoids "missing file" errors common in modern sets by using a snapshot of arcade history that doesn't change frequently. About ROMs & CHD's - EasyEmu : MAME Guide Error 1: "One or more ROMs/CHDs are missing
