Yamaha still make one FM chip, the YMF825 (. SD-1), which has some striking similarities to the OPL3 used in many PC soundcards in the 90s. I wondered if the SD-1 might be able to play OPL music, and if so, what it would sound like. I built a USB interface and OPL to SD-1 translator, and tested it with various PC game and tracker music - here are the results. Schematics and firmware for a device similar to the one used in this video are available here: Music: 00:05 - Tim 5 (Lemmings) 00:31 - Intro (Flashback) 00:43 - Intro (Monkey Island 2: LeChuck's Revenge) 00:59 - Gorbi (KGB) 01:45 - Jamulations - Louis Gorenfeld / Extent of the Jam 02:45 - Monkey Island 2: LeChuck's Revenge 04:16 - Spice Opera (Dune) 05:38 - Samsara - Diode Milliampere 07:10 - Wacky (Oh No! More Lemmings) 08:21 - High Tech Environment III - Benjamin Gerardin 09:51 - Spiral - Phandral
