notes: |
  Stripped-down MAME 0.78 build with only 4 Midway driver files
  (midtunit, midwunit, midxunit, midyunit). Targets RAM-constrained
  devices that cannot load the full mame2003 core. Supports ~50 games
  (Mortal Kombat series, NBA Jam, Smash TV, Total Carnage, etc.).

  No shared BIOS ZIPs needed — all Midway games are self-contained ROM sets.

  Uses system_dir/mame2003/ for data files (shared path with mame2003).
  Data files are not bundled in this repo.
