Hidden Urusei Yatsura tune in Gunbuster vol 1

[_Paul]

I was going through a music rip ROM for Gunbuster when I stumbled across a couple of interesting things. First were some tracks that I did not remember from the game - the sound quality was noticeably different (better) than the in-game tracks. But then I came across one track in particular which grabbed my attention. It was a version of the title song from the anime movie 'Urusei Yatsura - Remember My Love'
The original tune can be found at 3m 55s in this video (movie ending spoilers before that).

The PC Engine version can be downloaded here.

I'm assuming that this was idly composed by the programmers and hidden in the data somewhere - I'm not sure how these music rips are created, but I guess they must all be from the Gunbuster code and not somehow stitched in from different sources. I've not come across any other hidden music of note in other games but I'll keep looking.

Was the UY game for PCE also made by Riverhill Soft?

No, Hudson Soft made 'Stay With You', no connection to Riverhill as far as I can tell.
