The software I use to make these covers is called Furnace Tracker - tildearrow.org/furnace/ Getting custom FM instruments requires getting vgm2pre - vgmrips.net/wiki/Vgm2pre Getting vgm formatted songs from games requires vgmrips - vgmrips.net/packs/ Next, open vgm2pre, and press on Tools -> Preferences -> Uncheck all boxes besides the box labeled DMP Then, click on File -> Open a vgm formatted song and then click on Dump Then, open Furnace and click on Open (the little file folder) -> Select all the instruments downloaded from vgm2pre Finally, save the instrument as a Furnace Instrument
