GameBoy Online (2011/12/24) 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:
- Removed WAV generation support as a fallback in XAudioJS.
- removing some non-required files.
- XAudioJS update.
- Finishing out an update.
- Google Chrome on Windows is slow with graphics, so re-enable the nearest-neighbor CSS prop for it.
- Implemented document.hidden checking for setInterval 1000 ms clamping.
- Implemented the vendor specific versions of the Visibility API.
