I just modded my pal aes to 6ohz by cutting the jumper on the pal connection and now all my games run full screen and faster than before, its also cured alot of graphic problems on games like burning fight and riding hero, but what i wondered is my power supply is set at 220v 50 hz, thus running at 60hz will surely pull more load on it, therefore is there a risk of knackering up the power supply?
