: The original developer (Chris J.) passed away, and the project is currently unmaintained as the source code was not released. Current State

Want to get in on the action? Here is a step-by-step guide to setting up your own MFME arcade. Be aware that most files are shared via free, community-run sites, which may require registration.

If an old MPU3 or MPU4 machine is running too fast or sluggishly, right-click the running layout to access the configuration menu and adjust the emulation speed and refresh cycles to match native hardware.

Getting started is straightforward:

Because many of these machines used custom ASIC hardware with no available datasheets, the developers of MFME essentially had to reverse-engineer how the hardware interacted with the physical world. This is why the "extras" (the visual layouts) are so crucial—they provide the visual context for these complex mechanical simulations.
