I always thought space road should be the bgm of rainbow road in mario kart, now that you made a mario 64 sft cover, then I know I was right. and thank you for your cover.
This is probably too late but from my experience you simply need a Digital Audio Workstation (DAW for short) or some program that includes soundfont playing capability. Pretty sure the famous FL Studio has that but free programs such as LMMS (which I use) and Musescore also have this capability. Basically just search for music programs that have soundfont functionality and then search a tutorial for how to set up the program and use soundfonts.
