MUgen is an emulator generator which works in a way similar to yacc. It takes an input machine description and outputs a source file which is a fully implemented emulator of that system. This is the open-source system.
More Than Parsing is a parser generator for context free grammars defined in a BNF-like format. It generates scanners, parsers, ASTs, etc. This sf project is no longer active, development will continue in a different place.
