I just got my psp, and I've been going crazy trying to figure out how to play downloaded games from my pc onto my psp. I recently figured out that I couldn't on the firmware that I had. I then upgraded to 3.50, the newest firmware, and I still can't figure it out. I downloaded some psx games and put one on my psp and it's there, but it says "please start system to play this content". Could someone please help. What does that mean?
