Note: This procedure involves changing a game file;
create a backup copy of the file before proceeding. Before starting
the game, open Windows Sound Recorder. Select "File"
and go down to "Open Or Load File" then search for the
"Robot Arena" folder and open "Sounds". Right
click on the sound that you want to change, and click "Play".
If that is the sound you want to change, double click it. This
should bring you back to Sound Recorder. Go to "Options"
and go to "Delete After Current Location". Press "Record"
and make a sound . Replay it, and if you like it, save it. Play
game and if done correctly, you should hear your sound rather
than the original sound.
