Then my guess is that the CSO files you have somehow got corrupted and the PSP isn't reading them anymore. You'll have to redump the games.
My fat PSP was upgraded with firmware 3.90 via the upgrade version in my PSP and now it won't able to detect any ISO/CSO formatted games in the memory stick. I've been searching for a thread within this website and found out that some of the features mentioned e.g. press SELECT key to enter the homebrew selection menu or cold starting PSP by holding R key, there's nothing happen.
Appreciate if anyone able to assist here. This is my nephew's PSP (6 years old) and I've promised him that it will be fixed by this weekend!
Need advices so badly here...

1. Will this always be the same pattern? We have to update to X.XXM33-1 then X.XXM33-Y where X.XX is some new version, and Y is any sub-version..?
2. What you do miss out is the confusion of the 1.50 kernel addon. Is this compulsory if we want to run homebrew in the GAME150 folder?
3. If I installed 3.71M33-1 then installed the 1.50 kernel addon. Then I install 3.71M33-4 (at a later date) will this override the 1.50 kernel addon?
I'm trying this for the first time. My PSP fat is running with Sony firmware 3.80.
I've tried a few different guides and tutorials for putting on custom firmware, but no luck. When I attempt to run the installer from the memory stick, it starts as if a game is about to begin and it tells me: "The game could not be started. ( 80020148 )"
What am I doing wrong, and how can I fix it?
