So I bought a PSP off eBay a couple weeks ago, it was pretty much brand new. It had everything with it and stuff. The sample disc that came with it worked and a game that I had purchased previously worked on it. Then I went out and bought Metal Gear Solid: Portable Ops. This game did NOT work on my PSP. It would load it, it would should the little preview screen but when I click on it to start, the PSP logo shows and it just goes to a black screen. It stays on the black screen and just makes weird clicking noises, almost like it's skipping. I have 5 games now plus the sample disc. 3 of the games work and two of them go to a black screen, followed buy a clicking noise. I've tried these games on a friend's PSP and they both worked on his. I have the proper firmware to play these games, I've even taken them in for a replacement game, just in case. They still don't work. So now I'm down like 80 bucks in games and I would like to know if anyone knows why this is happening and if anyone knows how to fix it.
