Hello! I haven't needed to upgrade my psp for awhile and have been running m33-6 with no issues. Unfortunately I tried to play the new dissidia, and it's not working. I did some research and it looks like I need an update to play 6.20+ firmware games.

So I tried to install Prometheus-4. That isn't working though, and is giving me "Copy File Error (0x8001001c) Install Aborted."

Does anyone know what could be causing this? are there any other alternatives to this method or any "recommended above all" methods of playing new games on psp1000 running 5.00 m33-6?

thank you!
