I have a very hard to find OST that I am trying to look for. It is from a arcade game that only had 7 boards manufactured. It is called Riot and it uses the same hardware as Tecmo's Ninja Gaiden arcade game from 1988. It was made by NMK Co. Ltd. in 1992, and it is a very rare game to rip the music off of.

Here is footage of that game: YouTube - RIOT (NMK, 1992) - UNRELEASED ARCADE GAME (http://www.youtube.com/watch?v=9nnvVWUY6Vg&feature=related)

Here is even more footage: YouTube - Riot (http://www.youtube.com/watch?v=mB96IkL0jp4)

If anyone can rip the soundtrack to this rare treasure, I would appreciate it.

Anyone? I'd also like to see some BGM ripped from these arcade games:

Zero Team
New Zero Team (contains some exclusive songs)
Ninja Baseball Bat Man
All TAD Corporation games
All Tatsumi games
