Black Silk XMB Theme

Here's one dark looking theme for your XMB: Black Silk. It comes in two versions, one for 3.52 M33 and one for 3.71 M33, so download the correct version for your PSP's custom firmware.

Here are some pictures of the XMB Theme:

Some flashing instructions are included inside the RAR file, but I'll repeat them here again so you can read it one more time.

For 3.52 M33
Just enter recovery menu and toggle USB flash0, then copy over the files to the respective places.

For 3.71 M33
Flash the updated usbdevice.prx first, else there is a random chance of a full brick.

Once you've done that, you can enter recovery menu, toggle USB flash0, and copy the files over like how you would on 3.52 M33.
