Simplifying the whole theme creation process for firmware 5.00 is Bubbletune & Davee with two handy tools — VSH Module Descrambler (for Windows) and Scramble Patcher (for the PSP itself).

VSH Descrambler:

In 5.00 Sony took a different approach by no longer storing the floats in separate words, but instead loading them using opcodes. This has made it harder to impossible for theme developers to find these floats, so we’ve decided to develop a tool to take it apart, and put it back together.

In order to use this utility, you must descramble the PRX file, and a file containing only the floats in the PRX will be returned. Modify whatever you want there, and then use the application to rescramble it again. All should be pretty straightforward.

Get it? Got it? Good. Onto the next…

Scramble Patcher:

This plugin allows to patch modules on-the-fly with the scrambles in ms0:/scrambles/*. To use this is easy, all you have to do is get a scramble for the VSH Module Descrambler and put it in the ms0:/scrambles/ folder named the same as the module which it came from (vshmain scramble becomes vshmain.bin) with a .bin extension.

Using this allows quick turn around times for finding values in the scrambles. You can simply just modify it from the memory stick rather than descramble it from the prx, apply edit, rescramble and then flashing it.

So there you have it. Each download comes with its own readme for further clarification. Happy theming!
