New version is live !!!
If you have issues, try upgrading Flash Player to latest version (12), and clearing your browser cache.
The new version brings :
SAVE / LOAD buttons with confirmation (no more messing with F1/F2 keys). F1/F2 method still work if you want to mess it with. I will remove it in the future.
PAUSE / RESUME buttons.
FULLSCREEN button to switch to full screen mode. Aspect ratio is NOT handled yet so it might look crap on vertical games or 16:9 screens.
TOGGLE SOUND ON / OFF buttons to mute the game.
Also this version introduces unofficial XBOX360 controller support.
Please note you need to unplug / replug the XBOX360 controller once game started to use it. This is a Flash bug which sucks a lot.
No other controller is supported so far, please report how it goes with 360 controller.
