I am porting this project to a Chrome app. It will be able to run in the browser without an active internet connection.

GB/GBC icons: http://starvingartist.deviantart.com/art/Antiseptic-Videogame-Systems-23217105 Other icons: http://www.famfamfam.com/lab/icons/silk/

Borrowed some old Chrome NTP code to make i18n stuff in HTML easier (see source for details).

TODO:

• Look into registering this App as a handler for .gb/.gbc files on Chrome OS.
  • Seems to sort of work, need to test a little more.
• Add keybindings to simulate tilt. (Support doesn't seem finished yet in the emulator.)
  • Simulating with mouse/gamepad will probably be better.
• Add support for gamepad input. (API seems broken in Chrome)
• Try to get it running at an acceptable speed on a Cr48.

Known browsers to work well in:

• Firefox 4+ (Windows 7, Windows Vista, Mac OS X)
• Google Chrome 18+
• Safari 5.1.5+

Browsers that suck at performance or fail to run the code correctly:

• Firefox 4+ (Linux + Windows XP versions of Firefox have audio lockup bugs)
• Opera (Crashes + Slow + Graphics Glitches)
• Safari 5.1.X (Below 5.1.5) (Slow or crashes)
• IE 1-8 (Cannot run)
• IE 9-10 (Slow)
• Firefox 1-3.6 (Slow)
• ALL VERSIONS OF MOBILE SAFARI AND OPERA (Stop pestering me, iOS just CAN'T run this well.)

CPU instruction set accuracy test results (Blargg's cpu_instrs.gb test ROM):
