Dark420bishop's made another useful icon tool for those people who love customizing their PSP. Topmenu Icon Extractor v1.0 will extract the 6 main icons from a decrypted 3.0x topmenu_plugin.rco for you to use and tweak (yet again) to your liking. Combined with something like the Topmenu generator, dark420bishop's own Submenu Icon Injector, and the Custom XMB Icon Packager, you could be looking at a ton of new icons for use on your PSP.

Before anything else, he notes a couple of things you'll have to remember beforehand. Dark420bishop says,

This program only works on standard topmenu_plugins, meaning if the person who made it changed the pointers, the icons will be in different places and when extracted will look jumbled.

He also requires people to have a decrypted topmenu_plugin.rco for 3.0x and the Visual Basic 6 Runtime Library before they can use this, so be warned.
