Hey guys, I'm really sorry for this n00b post but I installed the wrong version of Doom, I did the 2006 one. :\ I've been able to uninstall the other non-working homebrews by deleting the "corrupt files" in the application manager. This Doom install as far as I can tell is in the actual PSP folder and is not seen by the Vita as a program to remove. Is there another utility I can use to delete that?
I'm guessing my options are suck it up and live it with it or format my card...I did back up Super Collpase on my PC but I'm paranoid to go this route, I'm not sure how easy it would be to put it back.
