GameBoy Online (2012/02/20) 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:
- Rewrote how freeze states are stored and shown. Also added the option to download the binaries in my custom format.
- Cleaned up some lcd initialization.
- Close the freezeeeze state window when launching the state.
- Added some safety to base64.js for the non-native base64 encoding function for browsers that add mystery upper bytes.
- Landed save file importinggit add ./! You can now save your game progress and load it on a different computer by using the save manager to export and the save importer to import.
