Frontend

Beta testing v1.03

MameDuo H2H project

MameDuo.exe is a custom head-to-head arcade frontend that runs two game sessions side by side on a single PC and single display, so each player can load, reload, and change games without interrupting the other side.

  • Runs two live game sessions at once on one machine and one shared screen
  • Supports independent left and right gameplay with live game swapping per side
  • Can run as a standalone app or be built into a frontend for more flexible cabinet setups

Utility

Optional wrapper

PreMame MAME Wrapper

Load separate per-game console .lay files while keeping a safe shared default.lay fallback for systems where MAME normally expects one common artwork file.

  • Temporarily swaps a matching per-game layout in as default.lay for the current launch
  • Restores the original shared layout automatically after MAME closes
  • Designed to pair with Layout Builder exports for console systems such as SNES, Genesis, NES, or SMS
