Please hear me out, I bought a PSP many years ago (psp 1001).
I applied a hack and was able to boot .iso and emulation via dev hook.
The system software is version 1.50
I haven't used the machine in years, dug it out, dusted it off, and it works as new.
My 6 yr old son has developed an interest and I would like to pass it along.

Since I have no idea what CFW I installed back in the day, should I update the psp with OFW first? I think I want m33 CFW but what version?

I'm not asking to be spoon fed, just a nudge in the right direction.
All I really want is pop-station.

So I have a psp 1000 with unknown CFW and want to upgrade to the latest and greatest CFW.
Suggestions much appreciated.
Thank you for your time.
