Just 3.90 is the Official Firmware. It’s the one Sony ships with new PSPs that lack the capability to play ISOs/CSOs and homebrew apps which to say the least means you need to buy Game UMDs in order to enjoy it. 3.90 M33 is the Custom Firmware which gives you the said options and more

so…. if you currently have 3.80 M33 and you go all the way to the top left of the XMB menu where it says network update the psp will get 3.90 M33 ??

Hello Joe, seeing as you are still using the official firmware, I’d like to ask what kind PSP do you have? Slim or Phat? If you’re on a slim then you can just install 3.60 M33 on it then move up to 3.71 M33 then 3.80 M33 then 3.90 M33

If you’re on a Phat then you have to downgrade it all the way to 1.50 then move to 3.52 then 3.71 M33 then 3.80 M33 then 3.90 M33.

A guide can be found on my earlier post, here.
