Inspired by an idea presented by senior_falcon, I have written a Java utility to extract sound lists from TI files.
To run the program, unzip the attachment and double click the jar file (you need to have Java runtime 6+ installed).
Once the program is running, go to the File menu and choose 'Import Sound Lists'. Browse to a directory with TI files and select one or more files to rip. You can choose almost any type of TI file: E/A#5, ROM, GROM,
