I have 6.20 PRO-C from years ago... concretely-speaking, what's the difference between that and 6.60 PRO-C2?

PSP to sleep or turning off, it won't turn back on, just displays a green power light, nothing else. I need to completely turn it off, swap back to the old 4Gb card and turn on, everything works fine (albeit with 60Gb less room for games).
Hi There. Earlier today i found an old psp in storage. I bought it years ago, already modified. i wanted to upgrade it but everything i try gives me a message that says "the game could not be started. (DADADADA)"
System software says 3,52 M33
i read thru about 4 pages of comments here but didnt see anything like ti happening and I don't know much about hacking....
Hey guys, my psp doesn't show the update files or any of them when i put them inside my game folder,it says that your stick is empty or something, i can't seem to fix it so i updated my psp to 6.61 and still i can't see them, any suggestions?
i also tried to fix them by copying folders from my other 2 psp slim and the 3 of them are messed up. 3 of them are slim
Is the 64gb card a Dual MicroSD to MSProDuo adapter?
I seem to remember the PSP had issues with anything above 32gb, i'm not sure if that's changed however 32gb was the limit when I was last using my PSP.
Use Hellcat Recovery Flasher v1.65 to flash an 5.00 OFW then you can follow this tutorial updating to 6.60 and finally installing the CFW.
Flashing OFW can be risky so keep that in mind, do so at your own risk.
PSP Recovery Pack Download - this includes the 5.00 update and a 5.00 CFW. I believe from 5.00 CFW you will have no problems updating, although it has been a long time since i did anything with the PSP, so can't be 100%. Just trying to help you the best I can.
Format the memory card on the PSP, then copy the files across.
If you still have issues upload some screenshot of what is on your PSP's memory card.
I tried formatting my memory card and then copied the cfw files onto my Game folder and nothing happens when i switch to psp it says, "There are no games. Content can be downloaded or purchased from the PlayStation Store. I also tried to do the same thing with the video folder but videos does not appear."There are no videos."Is the 64gb card a Dual MicroSD to MSProDuo adapter?

Yes, and the memory stick is working and functional.So on your Memory Stick you have \PSP\GAME
Then inside the game folder you have CIPL_Flasher, FastRecovery and PROUPDATE
It's fixed, turns out i had some sort of virus that made my actual psp files hidden and showed the fake ones. Sorry for the problems i've caused :xSo on your Memory Stick you have \PSP\GAME
