Though it would be impossible to make a perfect copy of a PSP game due to the limitations of what a UMD Burner would be, just the same as it's impossible to make a perfect PSX or PS2 copy on current home burners. Granted there are possibilities that a burner can be reconfigured, or somebody gets a commercial press. The reason PSX and PS2 discs don't work without a boot disk or somethin is all due to the fact the Boot sector isn't burned into it. It's amusing....somebody could put multiple PSX games on a DVD and write a boot program for the PS2, they'd need only a press that can write the boot sector. The same problem would be inherent to UMD without a commercial press. For those who don't know...DVD presses go for over $10,000 i believe.
