It is an emulator of legendary Fujitsu FM TOWNS computer including Marty. The goal is to emulate model II MX, which was the last computer I pledged allegiance. Also I am trying to find and document undocumented features of FM TOWNS system as much as possible while writing the emulator.
Have been tested on Windows 10 and macOS. I think it runs on Linux, but I have a report that audio doesn't work on the natively-running Linux. I can hear audio on my developing environment on Virtual Box. I haven't been able to confirm the report on my side yet.
