I am attempting to rip two UMD games. "Star Ocean: Second Evolution" and "Lunar: Silver Star Harmony" to my PSP 2001 Slim which has CFW 6.60 me. The games play without issue from the UMD, and I am able to connect the PSP to the computer with the data cable, view the ISO, and begin copying. The problem is that after around the same percentage is done copying, the PSP suddenly shuts off without warning. The power cable wasn't plugged in the very first time and I simply assumed the battery was dead, but with it plugged in the same thing happens. Furthermore, the light that shows it is charging shuts off as well and I can't turn it back on unless I unplug the power cable and then plug it back in. When I do, and reconnect the USB connection from the system menu, I can click to resume the copy. Sometimes when I do that though it says the file was externally changed and I have to start over, not that it makes a difference because even when resuming it really starts over. Anyway, I know that if I can't figure this out I can easily download the files (and no it's not piracy if I own the discs), but I would really prefer getting this to work. Is this a symptom of just dirty discs? If so is there any way to properly clean them considering that the UMD cases don't come apart?
