C64 M.U.L.E. Theme with Harmony

Most hardcore M.U.L.E. fans would likely agree that the Commodore 64 version of the game theme sounds superior to the Atari 800 version. However, due to a limitation of the C64 sound system (one less sound channel), it is lacking a significant component–the harmony and counter melody that is only present in the first version.


Something hackers did, even as far back as the 80s, to expand the sound channel capabilities of their C64s was to patch in additional hardware into technically unused spaces of the address bus, allowing for more channels. That’s great but little to no published games were developed to take advantage of this customization.

After doing a bit of reverse engineering, I’ve managed to study the music engine of the game and isolate the music data from both of the “good” versions of the game. I expanded the music engine to support an additional channel and supplied it with the missing song component.

So, here is what the C64 version should have sounded like, available after all these years; enjoy:
