When people want to write an emulator, Gameboy is usually the platform of choice, since it’s relatively simple, relatively common and relatively well documented. With the advent of faster Javascript interpreters and Canvas, it now seems like Gameboy emulators made in Javascript is an emerging trend.
The latest addition, tentatively called “GameBoy Online“, made by Grant Galitz, adds GBC support and primitive, pretty crappy, sound support, something the first two don’t do. It also has a fancy GUI. It seems to be slightly slower than the other two, however. Perhaps I ought to benchmark the three existing Javascript Gameboy emulators and see how they compare.
To try it, you need a ROM image. You can either enter it as base64 (Use a tool like this one to convert the file) or use one of the following URLs:
