Download WAWI at:
Install this and restart winamp (if previously started before installation)
Configure your port for the HTTP Server to what you wish in the Winamp options, plugins, general section. Now you must give the anon user "play" permission. Make sure that you DO NOT set a password for this account.
Download the newest plugins for pspradio:
PSPRadio Plugins 1.38.91
After unzipping these into the PSPRadio directory, make a folder in your PSPRadio directory called "APP_Retawq". Then you must follow the link for the tips.txt file that you must edit. After changing "localhost: port" to be your computers IP address and the port you set WAWI to listen on, you should save this file as "tips.html" inside of the "APP_Retawq" directory that you created.
Now you may start up pspradio, begin listening to a stream, and then go to the plugins menu and select retawq to control what you listen to. Below is an image of the interface.
Using this method you can control winamp while listening to a shoutcast stream all at the same time without pspradio crashing.
EDIT: This method is now outdated due to the release of the links2 plugin by raf! Direct the url for links to your "localhost: port" (Ex: 192.168.1.5:8000) to access the WAWI interface. This method now supports logging in with your own username and password along with the ability to select song playing and even download the song to your memstick! Utterly amazing work.
