Never thought this would be a problem. Have ISO of Ratchet & Clank Size Matters. I deleted the saved file of Ratchet & Clank from memory stick while I still had the Ratchet ISO on the memory stick. Now the ISO won't work when I start it back up. I even reformated memory stick and got it back to what it was before the incident. I went so far as to get a different copy of the same ISO and it won't work. I am using DEVHOOK 0.4X LAUNCHER for 2.71. I almost thought it could just be a bad ISO but it did work initially whereas some bad ones I've come across won't load at all. Now this one is reacting the same as a bad one. It will start to load (go to the ESPALPSP starup) and then go black. Any other ISO I put on the memory stick will work. Any ideas anyone?
