Hello, Since I'm out of the loop for a long while, the question is that simple: Should I upgrade from 5.00 m33-6 firmware to 6.20 PRO-B5 ? I heard some games doesn't work on old firmwares. Also, some people told me that I should not upgrade, but they couldn't give me a good reason for it. Since you guys are the best at this stuff, what's your advice ? Is there any good updates or fixes for 6.20 firmware ? (Or maybe, even 6.35 I guess ?) My PSP is the ancient one (PSP1001 on the bottom label). Thanks in advance!
