well, a bit more info would be helpful

Theme type (PTF, CTF, or Flash0?)
And Firmware (official or custom)

what kind of themes?

PTF files go in : mso:\PSP\THEME

CTF files go in : mso:\PSP\THEME (CXMB needed)

for flash0 ... its a little bit more complicated but theres a guide in here somewhere :)

download.. .. please read the readme on how to install :D

Place all the folders in the root of your memorystick (that is X:\, where X is your drive letter)

Turn your PSPcompletely off, and boot into recovery mode (if you don't know what this means, you probably don't have custom firmware, and therefore cannot use CXMB themes)

Go into plugins, higlight CXMB, and press X (should switchto enabled)
Go to Setting, Theme Settings, and select theme, which is where future CTF files should be placed (X:\PSP\THEME)


Anyway, ignoring that,this is the version of CXMB you should be using
