GameBoy Online (2011/08/08)

via http://www.emucr.com/2011/08/news-ga...-20110808.html

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.

Recent Changes:
- Adding hacks for Game & Watch Gallery 2 CGB running mode even with the header correctly.
- Update XAudioJS.
- Optimization of CPU instructions 0xFFXX reduced when writing.
- Remove the trash.
- Remove obsolete entry in the manifest.
- Reverse playback of the gyroscope as it should be.
- Launch of UpdateCore in the path of the loop of the interpreter. Optimization of the TIMA clock
