To create PSP themes using CTFTool you must understand the CTF theme components

• The XMB on the PSP is known internally as the "VSH" and since the advent of homebrew is highly customizable. The firmware files vshmain.prx and paf.prx contain the main positioning of the icons and the layout of the XMB.
• Topmenu_plugin.rco contains the menu icons as well as the glow and shadow icons for each menu icons (3.52 and below firmware), and for 3.70 and above firmware, it is named Topmenu_icon.rco. Topmenu_plugin.rco also holds the names of any of the icons in the XMB (on 3.52 and below), and for 3.70 and above it only stores text.
• System_plugin.rco file stores components such as XMB sounds and the busy icon and system_plugin_fg.rco contains the battery icon. Impose_plugin.rco in the other hand, holds the sound volume icon.
• System_plugin_bg.rco contains the background animated wave. Before the firmware update 2.70 was released, it was very easy to edit the menu background colors by just editing the BMP files at FLASH0:/VSH/RESOURCE files 01.bmp to 12.bmp, but after the update all the background BMPs were held in a single BMP file named 01-12.bmp. The files were added after each other in the BMP file by simple HEX editing. That way opening the file in Paint for example, the user would just see the first month background color which is grey.
