I'm quite impressed with the work-arounds. I might have a look at the source.
Neat, but it runs real slow. At least for me.
That is bloody amazing.
It runs really slow in firefox but then I tried it in google chrome and got a steady 60fps!
This is a really great find, just for contra and donkey kong!
Good advice ... need to try it out with Chrome, too!
