I've been out of the scene for a while and would like some help: I have an old fat psp running 5.00 M33-6. A while ago, I wanted to play a backup of Valkyria Chronicles 2. I can't remember, but looking at my mem stick it looks like I used Prometheus Installer M33-6 by Red Squirrel. Either way, I have the Stargate.prx in my setplugins, and ms0:/seplugins/Stargate.prx 1 in game.txt I have a fresh ISO of Monster Hunter Portable 3rd that I can't luanch, "The game could not be started. (80020148)" I've tried a few things. First, like an idiot, I used Classic install of Prometheus Installer which didn't fix my problem. Then, like an even greater idiot, I used the "Install all in Flashs" option and no games were loading at all. I fixed this by disabling the Stargate plugin, then uninstalling the "Install all in Flashs" option, re-enabling the Stargate plugin. Now I'm back at square 1, my games load, but no MHP3rd. I tried patching the ISO using iso_tool 1.980 using the patch prometheus4 option but that didn't work either. Maybe I should try applying the patch manually? I can't seem to find a good guide on how to do this. I'm out of ideas, is there anything else I can do? I'd rather not upgrade my CFW. Thanks for your help!
