Info is pretty slim on this one, Any help is appreciated!
Spotted on Yahoo Japan Auction.

Catalog number is identifiable on the bottom right cover.
The logo on the bottom left is used by NEC Avenue, although this Promo is from 1988 and currently NEC's earliest album in the database is in 1991, so this could be very early works
I'd guess the artists would be "3dl" for 3 deciliter, and that only the first track is from a PC-Engine game. (the other 2 probably being other works).
Although a quick search didn't yield a match for a game with "Andromeda" in the title though, but PC-Engine logos abound, so there must be some game represented here...
