Tired of the regular click sound on your PSP? As long as you're looking around, you're bound to find some application out there that allows you to pimp your PSP even further. Now here's Wav-to-Vag v3.0, a useful app from Highboy gives you a bit more leeway in customizing your key tones.
It's simple really. All you have to do is install the application on your PC and drag the file you want converted. You can convert Wav files to Vag format, or vice-versa (convert Vag files to Wav). Once you're done, just transfer the file to your memstick and you're good to go!
