It pains me so...

[noob disclaimer]Please don't hurt me, I've spent hours trying to fix this. Being a mod on another forum I know how annoying it is when people haven't looked before asking. Understand this is a last resort.[/noob disclaimer]

I've downloaded themes from this thread: http://endlessparadigm.com/forum/showthr...p?tid=1164
It's the one recently stickied in PSP Customization with 3.40-ready themes.

I enter my recovery menu, go to advanced and enable flash0 via usb.

I go into font and change the gb3s1518.bwfon to a blank file to free up some space - this works fine. I have stopped the process at this point and everything works as it should, ergo I am confident this not the problem.

I go into vsh/resource on my PC and get a big list of thingies.

I open one of the theme packs and get a similar list of thingies.

WARNING: Dodgy bit

I then copy the list of thingies from the pack and paste them into vsh/resource (the other list of thingies). This theoretically overwrites the normal ones with the custom ones.

I disconnect from the PC safely and start the PSP.

The theme works! ...But nothing loads in the Game menu.

Why? Oh Why?

Someone put me out of my misery, please.
