Case study

Butterscotch: rebuilding the GameMaker: Studio runner

Butterscotch reimplements the GameMaker: Studio runner in C so exported games can execute on additional platforms. It interprets GameMaker bytecode and documents support for WAD versions 8 through 17, with desktop, web, and console targets. Bytecode support remains in progress, and native-code YYC and GMRT games are outside its stated scope.
