I'm just cruising through the posts right now, and there are a lot of people still installing the 3.1 Don't waste your time and money - the 3.1 will be obsolete soon. The Magic V is basically the same price, and will play these new double-check protection games - AND boot from the browser. There is nothing more frustrating than getting into a game, passing a level - and when it goes into auto-save, you get the 'red screen of death'. Do yourself a favour. Cheers!
