This will eventually be a multi-system emulator. Probably not for awhile. It will be slow for even longer. Likely forever. At least there's Inline::C. ¯(°_o)/¯
The main reason I started this project was because I saw this and thought it was the bee's knees.
Currently there is most of a 6502 simulator + monitor, along with test suite. It would not surprise me if it's completely broken.
Enjoy.
