This project aims to implement a DefleMask-inspired (and -compatible) FLOSS chiptune tracker which supports accurate emulation of sound chips from various consoles, including:

• Sega Genesis
• Sega Master System
• Game Boy
• PC Engine
• NES
• Commodore 64
• Yamaha YM2151 (plus PCM)
• Neo Geo
• AY-3-8910 (ZX Spectrum, Atari ST, etc.)
• Microchip AY8930
• Philips SAA1099
• Amiga
• TIA (Atari 2600/7800)

I think this is a very cool project (just like DefleMask is!) and needs more attention!

(I discovered this program thanks to @milkii's (whom I thank ) Github starred feed)

furnace is indeed one of the very best "retro-crossing" trackers around, supporting around 50% of the chips supported from vgmtools specification
