I have 2 questions about downloading this game "BEATS" from US playstation store. 1. I am currently using 3.71m33-4 firmware. If i download the game after purchase, will it works? Do PSN prevent custom firmware PSP to be activate to their network? or do i need to do something to activate my custom firmware PSP to work with PSN? 2. After i downloaded and it works on my PSP CFW, will the game still works after i upgrade my PSP firmware to 3.80m33 etc in future? How to backup the license is what i concern most. Thanks!
