SOLUTION: Record one of OotG's chiptunes onto an audio cassette (chrome/metal with Dolby noise reduction). Loop the song until it fills entire 90 minute cassette.
Repeat process for each song.
Clearly label each cassette.
You now have, at your fingertips, every song for the game.
Procure a cheap sound mixer and tape deck (a Walkman will suffice).
Combine audio sources from TG-16 and tape deck with the mixer. You may choose to add a microphone, too, especially when narrating the battles.
As needed, insert appropriate cassette and press "play" and/or "pause".
TIP: Although some folks find it unnecessary, I enjoy combining the sound mixer with CMX strobe lights. It creates a very distinctive gaming experience. Personally, I also have a pair of tambourines nearby at arm's length, should the need for arise.
Have a very TurboXMAS.
