Gaming Why doesn't my 1.50 homebrew work?

[ackers]

I have a Phat PSP and when I was running 4.01 M33 and installed the 1.50 add-on I booted one of my 1.50 homebrews and it worked fine. Next day I booted it and my PSP just black-screened. It still does this now and I've updated to 5.00 M33-3 with the 1.50 add-on! What am I doing wrong??

EDIT: nvm, fixed.
