does anyone know how to flash a cintro? I have 4.01m33-2

Slim or original?

Original

I would like to know too, got a 3.90 phat and a 4.01 slim.

well i've heard it doesn't work but i'd like to know if anyone has any ideas...?

Get PSP Filer and put the cintro somewhere on your PSP memory card as gaemboot.pmf and find the place where gameboot.pmf is on your Flash0 and overwrite it with the first one.

isnt there a size limit though?

thats the gameboot

i'm talking about the Cintro, a custom intro like instead of the "sony computer entertainment"

Oh, haha. It's the same thing except it's cintro.pmf and it should be in the same location.
