Missing file for Prometheus

Cloud

Moderator
I am currently using firmware 6.35Pro with Prometheus and it has been working like a charm, but there is one major problem. The entire reason I got CFW was for MHP3, but when I got an iso for it and boot it up in Prometheus I only get a black screen and I have to completely reset my PSP. I did a little researching and apparently Prometheus needs an extra file called "isofs_550.prx". Where can I find this? Google yielded no results.

Auto-Merge: Also using psp 3000 if it matters. Please help :(
