Seems kind of slow? Or is it just me?

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.

z/x is a poor choice for control keys, especially for german speaking countries (we have QWERTZ http://en.wikipedia.org/wiki/File:KB_Germany.svg, not QWERTY)

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

Is it a really tiny screen for anyone else? I'd love an option to increase size (in a fancy block-graphic style like minecraft)

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

That's not the right type of scaling for that kind of graphics because the scalled image is smoothed and the graphics don't look as sharp as they should be.

IMHO they should support some scaling (x2, x3, x4, etc), even with CSS is possible, but avoiding that "smoothing" effect.

For me it runs with the correct speed (as measured with the ingame timer and I'm glad to see it's open source :) Nicely done!

Nice. When I see projects like this, I'm more interested in what documentations/tutorials they followed rather than actual product.

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...

Looks like it's 2 years ago something big happened on this project. I was surprised that it's written in Java compiled into JavaScript.

Sorry, am I missing something? I thought there were plenty of game boy emulators around, is there anything special about this one?

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

tnecniv3• 12 years ago

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.

Not bug free: grabbing the star doesn't make Mario invulnerable.

tnecniv3• 12 years ago

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.
