I have the last version of the game, so I extracted
the Special Game MIDIs. Though I want to say there were some non-MIDI songs that I may have had, but can't seem to find. Still, there's a full Special Game soundtrack... with some very direct theme repetition... and Sector 8's music is literally Sector 7's again.
Other notes: Jumper 2's final boss and ending themes, being original compositions not included with the J2 source, were replaced with the Final Fantasy 3 (NES) boss music and the Zelda 1 ending music respectively. The main menu music is "Intro Theme from Crash Bandicoot N-Tranced," which I don't think I ever knew. And the editor music is Team Magma/Aqua Hideout from Pokemon Ruby/Sapphire.
EDIT: I found a thing with original filenames, so I added who composed what for most of them.
(Yes, for some reason me7356 is credited in the filename for Sector 8 but not 7 despite it being exactly the same file.)
