GameBoy Online (2011/11/05) is released. GameBoy Online is a Game Boy and GameBoy Color emulator written in Javascript. It strives to be efficient and try to have a perfect compatibility. Currently the execution speed is not optimal even on browsers. For example on Chrome, which is nevertheless deemed to run Javascript faster on a PC running Windows 7 64-bit version with a double heart 2 CPUs at 2.2 GHz, games run at normal speed but almost skipping some frames.

The sound production is still experimental and rather poor quality. The video portion is by HTML5 or by creating images with BMP string URI. State backups are implemented using the object window.localStorage and are serialized / deserialized JSON. Ditto for backup SRAM.



GameBoy Online Changelog:
- Re-adding back requestAnimationFrameSupport. Q&A this for regressions.
- Specifying the v-blank event to the canvas rather than the whole document, for webkit internal rendering optimization.
- Optimized the software option of canvas scaling.
- XAudioJS update.
- oops
- Heh, I got a file mixed up from another repo
