I have japanese motherboard PSP (ver 1000 - no TA-082 afaik) with FW 2.0.
Do I need to upgrade?
Will there be any problems using the custom firmwares? (having japanese MB)
Can I downgrade from (let's say) custom 3.03 to my beloved 2.0 without GTA? Can I downgrade at all?
Do I need to backup my original 2.0 EBOOT or whatever before upgrading?
I am curious about upgrading, but I am not really sure about the benefits. I want to run homebrew, play fullscreen video, play music, play my umd games without hickups and do some wifi. What's the reason for upgrading? I can currently run some homebrew through TIFF/eloader.
