Now here's one good way to spend idle time with a PSP. Homebrew developer littlevish just came up with Pocket Gambler, a "cross between a casino game, and a text-based Grand Theft Auto." It may sound a bit simple at this point, but check out how a QJ forum poster's exploits turned out when he tried Pocket Gambler:

First I stole the windows source code and got away, I went to jail for stealing a psp, broke out, then went to jail again for stealing a car!

• Buy lottery tickets and play slot machines
• Out of money? Take a risk and steal things to gain money, but you might get sent to jail.
• In jail? Try to break out by yourself or by using special items. You can also behave well and hope for parole.
• If you have a lot of money you can buy items, and then sell them later when you are low in money.
• Coded in HTML and JavaScript
• Currently only text, will make GUI later
• High score submitting
• Game saving and loading. This feature currently only works on the PSP, but expect a PC version using cookies to save soon.
