Gambo: a Game Boy emulator

vim keys (hjkl) and arrow keys would be better.

This was our bible: http://nocash.emubase.de/pandocs.htm

We would use this as a reference when we didn't know how to implement something since this was the first time either of us had done any sort of emulation: http://imrannazar.com/GameBoy-Emulation-in-JavaScript:-The-C...

Press Control then use your scrollwheel. It's a web element. The default size is pixel perfect.

It's written in Java, that's compiled to JavaScript.

Dev here, other than the mentioned Java => javascript thing, not really. The two of us made this as a fun little project in high school a couple of years ago. Neither of us had done anything like it before, so it was just an educational thing really. We had ideas that might have been novel, but college started and we got busy doing various other things.

from what i remember of the last time i did turn on my old 2st generation GB (2 years ago or so) the speed is pretty much correct

Runs like a wounded animal on FF 29, Windows x64

For me too (i5-2520M laptop). This one runs faster: http://www.codebase.es/jsgb/

Seems too fast on IE, interestingly.

Good catch.

We actually spent a while trying to figure out what caused that, but it was impossible for us to use our usual debugging technique of printing traces on since that breaks down when user input is involved. We stopped working on the project before we could squash that bug. It's the only remaining bug as far as we know.
