Hi guys. I currently have an opportunity to buy a used PSP at a criminally low price, the only problem is that the UMD drive in the PSP is broken. Now my question is, should I buy it? The PSP has a 5.50 Gen-D3 firmware on it, and I only want to play the new Metal Gear game and Birth By Sleep, along with some older titles and emulators, but those two games interest me in particlar. Is that PSP with a 2GB memory stick all I need to do this? Is it true that UMD drives are practically useless when you play your games from the Memory Card? Will I need the UMD drive for anything in the future? Thanks in advance for the help.
