Well first let me tell you what i have:
PSP Phat with 3.90 M33-3
CXMB 3.1 for 3.90 (yea I checked to make sure I downloaded the right one.
Alright I followed the read me file that came with it for set up. So i copied the cxmb folder to the root of the ms then edited the vsh.txt to read ms0:/cxmb/cxmb.prx then I brought up my PSP and enabled cxmb in recovery mode. Then I copied a .ctf file in my THEME folder and then went to the theme settings in the psp and all it shows is the original. I also tired to edit the the config.txt file thats in the cxmb file to say the location of the ctf file i have but that doesnt do anything. Any help or ideas would be awesome.
