After many and many hours of downloading, I finally have Metal Gear Solid Portable Ops. I was so excited, couldn't wait to play it on my PSP. Well, I couldn't. When I try to start the game, a message pops up saying game could not be started. What the heck did I do wrong now? I have 3.10oe-a running and all ps1 games work so far. I dumped MGS into the root of MS in ISO folder. The file is CSO, nothing should be wrong. Why cant I play it?
