Help me find something

Hello, /prog/!
I have been looking for something recently and thought you may be able to help me! I am looking for something called "Graham's Tool"! It is on this site: http://www.devrs.com/gb/software.php but the link is dead! It converts .wav files to 4-bit GB format files! So if you know of any programs that can do this or how to can you help MILKRIBS4k!

I will publish my wave2gb program with code under the following conditions
1. You must start posting under the name Anonymous. Leave the name field blank.
2. You will never use the exclamation point.
3. Do not deny your anus heritage. You must embrace it.
