Author release notes:

I created this homebrew app so i could flash my own waves to my psp. It is fairly easy to use and it shouldnt brick your psp unless the file you select to copy is not a system_plugin_bg.rco file.

If anyone does use this then use it at your own risk and make sure you know how to change the system_plugin_bg.rco file in flash0 using the recovery menu.

Changes:

The bug in the previous version is now fixed.
Also i have made the application look better by adding a background image, etc.
