I have installed it all as it said, enabled all plugins, PSP Type B is installed, I have done everything right. So I hold Square and computer makes USB noise and usbhostfs says "Connected to device". I look in Memory Stick, and yes, all my ISOs are there. However as soon as I click on one and my gameboot appears, the computer makes the usb taken out noise. Then gameboot fades away, and PSP freezes with a black screen. I was using usbmount1.03 before and it made the usb taken out noise, but this was supposed to happen, then it said Game cannot be started, again supposed to happen, then click on it again and it worked, so I thought maybe would be same routine with this, but instead the PSP freezes! Please can someone help me?
