Always check your local laws regarding arcade ROM ownership – only keep ROMs for games you physically own.
Later versions of MAME require huge CHD files (Compressed Hunks of Data) for hard drive based games like Killer Instinct or NBA Jam (which can be 2GB each). In the 0.139 set, the vast majority of popular games (Pac-Man, Donkey Kong, Metal Slug, Street Fighter, Mortal Kombat) still run purely off .zip ROMs. No CHD management is required for 95% of the library. mame 0139 romset
For 0.139, the split set is standard. You’ll need both parent and clone ROMs if you want all variants.

Most 0.139 users skip CHDs entirely unless they specifically want those games. CHD sets for 0.139 are ~20-30 GB.

The 0.139 set supports the CPS1, CPS2, Neo Geo, and Sega System 16 architectures flawlessly. It plays Marvel vs. Capcom 2 (Naomi) with minor caveats, and it handles all the Cave bullet-hell shooters from the early 2000s.
What it doesn't play are the 3D polygon heavy hitters from the late 90s/early 2000s (Tekken 3, Gauntlet Legends) or the obscure, undumped Korean boards from 2005. But if you want to play Golden Tee Golf or Killer Instinct, you are looking at a different, heavier emulator anyway.
