See I was just at 3.40 oe-a and I downloaded this gameboot logo remover and put it into my flash0. It was dumb so I deleted it and then replaced the original file I overwrited. Then I tried to play one of my CSO's and it said "the game could not be started" Then some stupid number. So I downgraded to 1.50 and I put my CSO's in ms0:/ISO and it didn't show up under game. So I put in ms0:/PSP/GAME and it still didn't show up. I can play PSX games no problem. I'm not sure what to do. Should I convert my CSO's to ISO format? Thanks in advance.
