DECODED
These files contain intro audio. One file is only 144 bytes. Apparently it does not contain any valuable audio. There are 32 other files. They are mono 8-bit, sampled with frequency varying from 5 to 20kHz.
Provided: python script for extracting both intro and in-game sound files and converting them to .wav format. You need dernc and sox to be in a directory which is in your $PATH variable. sox is a audio files converter. Get it at http://sox.sourceforge.net
