This is a custom all-in-one board that lets you put a Raspberry Pi Zero or Compute Module 4 (and CM5 if you're adventurous) into a PSP shell. It allows you to turn your broken PSP into an emulation system or a fully functioning portable Linux system, all without making any modifications to the PSP shell.

Honestly it was much more fun figuring out how to do these things with the psp go, it just means I can add videos to my psp easier now

I have no custom firmware PSP is stock and on 5.50 currently. I can't update to 6.61 and have tried many different links to update.

it lets me install but when i load the update it throws up the error message 'the game could not be started. (80020148)'

I have my psp1000 with the pro-c cfw. I’ve been hearing about arc4 and I think updated arc6.
The question is:
Can I replace pro-c with arc4? Are there any steps I should take since it’s not the original firmware?
