Which Custom Firmware for PSP should I get? I have the PSP 1000. My current firmware is 5.00 M33-6. Should i update to 5.50 GEN? What is better 5.00 M33-6 or 5.50 GEN B?? Which has better Game Compatibility as well as homebrew? I know that you can't go on the PSP store with 5.00 M33-6 that why I kind of want to get 5.50 GEN. Is it worth it?
