It always sounded a bit crunchy, but crunchy in a good way. SEGA’s 16-bit console, whether you call it the Genesis or Mega Drive, always had a unique sound thanks to it’s Yamaha YM2612 sound chip. The chip’s ability to reproduce shredding guitars and blasting bass drums was a joy to hear when placed in the hands of capable game developers. Games such as Toe Jam & Earl, Streets of Rage 2, and Sonic the Hedgehog 3 provided some of the most incredible game soundtracks of the ’90s; and while the retail shelf life of those games may have passed, their influence on sound design should not. One individual that is seeking to preserve that quintessential SEGA sound is [Artemio] whose MDFourier project seeks to capture it for future generations to hear.
MDFourier is a crowd sourced project. Users are asked to use two pieces of software to first generate common audio through a videogame console, and another to analyze the output as to form an audio signature of that machine. Of course SEGA were not always known for their stellar manufacturing record. Throughout the dozen or so board revisions of the Model 1 console there were factory bodge wires, there was also the Model 2 console, Model 3 console, Nomad handheld, Mega Jet, CDX/Multi-Mega, and Wondermega karaoke machine. Each new revision of machine created a slightly new soundscape, and no single piece of emulation software takes them all into account. [Artemio] wants to aggregate all of this data in order to improve SEGA Genesis/Mega Drive emulators, FPGA implementations, or whatever else the future may hold.
Fans of the suite of SEGA consoles, or even fans of great documentation, can take a look at some of initial results as well as the written procedure for contributing to the MDFourier project. For those seeking a more visual step-by-step approach there is this video from YouTube channel RetroRGB below: If you’d like that Sega sound for your MIDI instrument, take a look at this MIDI synth using a Genesis sound chip.
