i got a PSP Go 6.20 PRO-B4. i was wondering what apps(like Bookr) do you recommend. links to said recommendation would be good please and thank you.

i was also looking for a app like Xplora. please dont say PSPFiler or w.e its called.i tried it and hated it. is there a Xplora app that runs on 6.20 pro b4?

and is there an audio boost plugin that works for pro b-3?
