XMB Wave background

[Zenith.XI]

Sorry about this, I've tried searching but couldn't find anything.

Anyway, I've noticed that on all the pics of custom XMB waves there's a black background, or in some cases a full image. I can only get my custom XMB waves on the default coloured backgrounds of the PSP.

So how does one change the colour, or image of the wave background?

01-12.bmp split/merge. gotta split it, put in you .bmp image, merge it back and replace in resource.
