Field notes
The launcher keeps the game’s original MAME behavior while coordinating rooms, player seats, countdowns, and match startup. Its lockstep model applies the same inputs on the same frame and displays ping, while the room flow supports private rooms and ping limits. The project also documents a careful division of responsibility: users provide mame.exe and their own cupsoc.zip, and the site identifies itself as unaffiliated with Seibu Kaihatsu and the MAME team.
