With the MAME 0.243 release we are pleased to also release QMC2 0.243 today.
This is the first version in about four years to work on Linux (several distributions), Windows and macOS again! Expect new binary packages within hours or days, but for macOS it may take longer. Follow these steps
to build your own if you are impatient.
Have fun, the QMC2 development team
for more information.)
