I had not touched my psp in a long while and purchased chinatown wars for a trip. I popped the umd in and I received a notice that said I must upgrade my psp.
I am now lost on how to upgrade my psp from 3.90 m33-3 to the latest custom firmware version so I can play gta chinatown wars.
Since I just read darkalex is no longer making custom firmware... what custom firmware should I be looking for? Can I upgrade directly or is there a downgrade/upgrade pattern I must follow?
What is the latest firmware I should get?
