GP2 Forum

I found something interesting: A Dos Emulator in Java, called "JPC". Should also work with Mobile Phones, but not with every.
It could be also possible that you can run GP2 with it...

It runs in the browser, I think you'll need a very fast computer to run a game like GP2 (my android 600mhz mobile surely won't do it). But it's worth watching its development (if there's any...the latest news from their website are from 2009).
