this has been a long-term project, but finally Winamp portable launcher is ready! its set out to the PAF 0.9 layout, and is mainly based upon the firefox portable launcher for its speed.
EDIT: I forgot to mention that it is for winamp lite, but in theory should work for all of them. as smithtech (down) said, just uni-extract it or follow the instructions in the app/winamp directory.
Also, its in BETA.
