Irem M92 Core

This is the MiSTer FPGA core for the Irem M92 arcade system (http://www.system16.com/hardware.php?id=747). The Irem M92 system is known for its high-quality graphics and sound, and this core brings these games to the MiSTer platform for arcade enthusiasts to enjoy.

The Irem M92 core includes numerous games that have not been ported elsewhere, providing a unique and authentic arcade experience. Some of the popular games available in this core are:

  • In the Hunt
  • Gunforce
  • R-Type Leo
  • Hook
  • Blade Master
  • Mystic Riders
  • Undercover Cops
  • Ninja Baseball Batman

Controls

All of the games use standard 8-way input with two buttons with the exception of Superior Soldiers which uses six button input. Several of the games support 3 or 4 players but you will need to change a DIP switch in the DIP switch menu to enable that. By default the button buttons are mapped to the MiSTers SNES-like layout as B,A,X,Y,L,R. The Coin and Start buttons are mapped to Select and Start. There are two additional buttons that can be mapped that are not mapped by default. P2 Start maps the the second players start button. The only purpose this serves is for accessing the service menu with a single controller since most games require pressing P1 and P2 start to access it. The second unmapped button is Pause which pauses the core.

Standard MAME keyboard controls are also supported for up to 4-players.
