Hi, It's been a while for me and I just found my gen1 psp that I soft modded so long ago. It's been a few years, and I see that I have 5.50 Prome-3 cfw installed. What do I need to upgrade it to? In the end I'm hoping to run emulations off of it and as I said its been so long. I figure I should start with upgrading it to the newest prometheus, but any other suggestion/better ideas and links are greatly appriciated.

Again, thanks for any help!
