i don't mind the brick risk really.
as i said, i don't like using things that are unnecessary. Flash0 works just as fine as cxmb does, and keeps the theme working after i remove my MS from the psp too.
rco's are also way easier to modify than ctf files are. (I've yet to find an app to unpack them)
i don't use my psp very much and i just wanted to have my theme back in flash0 as it was when i made a mod of organ for 3.71 back in the day.
the risk of bricking it while using flash0 is mine to pick too i think, so what's with all the "omg why not use cxmb" anyway?

What i really don't understand is why people see the need to tell me to use cxmb instead....
i asked help since i know there's people here who can do what i asked with ease and it would spare me propably days of examinign the prx / rco's to port the theme myself,
but it's ok i guess... I'll just try and figure it out.
