Technical 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.
