How to create XMB click

I am in the finishing stages of a my psp theme and getting ready to create a custom XMB click. I already have my audio file, so what utility should i use to inject/replace it in the opening_plugin.rco?

If you want the audio clip you can download it here, but i need it injected into my special o_p.r

it doesnt go into the opening_plugin, the click sounds r the system_plugin.rco
(srry that all i know, but plz upload & share ur theme)

wow opening_plugin.rco is bootsound i guess. i found that i can use rco editor to do what i needed after all. I just needed a program to convert .wav to .vag witch i found. Im nearing completion

cool, make it sweet! and good luck

We have a tutorial for this in our tutorial section as well, if you need something to refer to.
