Notes for this version: xmbWave is basically a simplified hex editing tool that alters the wave on your background, and as easy as the app is to learn, it's a tough one to become an artist. As you can see from the above picture from one of Darkstone's creations, finding a balance between going nuts in changing the values and knowing when to stop will serve users well in creating their own unique waves. It's probably the closest thing to a visual "fingerprint" you'll have on your PSP, seeing as two original creations will rarely be alike after editing.
Combined with icon makers and uploaders, as well as background manufacturers, this will really spruce up your PSP into something uniquely you.
Before anything else though, Vulpix wants to remind folks to check the readme and to not alter the values too much, as you could make the wave effect disappear entirely. Make sure you have a copy of the original starting values, just in case you do something very weird.
