I just picked my psp back up after a long time. I have a psp 3001.
Currently I am running firmware 5.03 and use the ChickHen R2 hack to then install Gen-C and play ISOs....
I was looking to come back to my psp and check out some of the newest games. I saw that there is this new CFW 6.20 pro-b5 is this something I should consider getting or need for newer games. Please someone tell me what the difference is between what I have, Gen-C...and this new one 6.20 pro-b5.

Any guidance/info you can give me would be much appreciated!!! Thanks!
