ADFtoMP3toADF is a tiny program I wrote to help people convert files used in the game "Grand Theft Auto: Vice City". The radio stations are ADF files, which can be converted to MP3 files quite easily. Its just as easy to convert back to ADF, in case you'd like to make your own radio station files.
Basically, all this does is XOR every byte in the input file with 0x22. The GUI should make using it fairly self-explanatory.
