The Emulator Framework was conceived, designed, and implemented by Steven Goodwin, between 2011 and 2020.
It is a system to build emulators, assemblers, disassemblers, and assorted tools
using a single description language.
The code is too much of a 'work in progress' to release, at the moment, but will
find its way onto Github at some point. But you can see the resultant examples on
these pages. It truly does work!
