Partial 6502 simulator heavily inspired by Nick Morgan's Easy6502 tutorial.
No dependencies are required other than JRuby.
To play a game of Snake6502, run:
$ ruby bin/vintage examples/snake.rom
To disassemble the bytecode for the game, run:
$ ruby bin/vintage-debug examples/snake.rom
All credit goes to Nick Morgan for the Snake6502 program. I didn't write it! But if you have any questions about the Vintage simulator, please contact gregory@practicingruby.com.
