Ganon's Castle Underground / "Hollengrund" MIDI?

Greetings forumers,

I came across these pages while searching for old school midis and it encouraged me to register due to all the kind help that others show to members here.

I've been trying to find a MIDI file of Zelda OoT's Track #75 - "Ganon's Castle Underground" which is just where you're exploring the lower parts of the tower. I used to have a copy of what seems to be a super rare midi out there years ago until my system crashed. Would anyone be able to help me with this please? Of all the songs people have created from the game in midi format, this certainly doesn't seem to be a common one... at all.

Thanks!
