Other soundtracks to other NMK games listed here:

NMK - GDRI :: Game Developer Research Institute (http://gdri.smspower.org/wiki/index.php/NMK)

Here's a rip of Saint Dragon, along with one of NMK's more obscure titles (which I don't see in the list you posted), Riot:

Saint Dragon (Arcade) (http://www.mediafire.com/download/5woi8cb57d80ats/Saint+Dragon.rar)

PCCB-00003 | SAINT DRAGON - VGMdb (http://vgmdb.net/album/589)

Saint Dragon was also featured in:

CDGM-10015 | Arcade Disc In JALECO -SHOOTING- - VGMdb (http://vgmdb.net/album/41165)

For Riot, that's more of a Tecmo game than an NMK game. It was featured here:

SRIN-1104 | TECMO ARCADE GAME CHRONICLE - VGMdb (http://vgmdb.net/album/45624)

Fire Mustang (Sega Genesis) and P-47 (PC Engine) are found in ruiner9's topic.

Have you also considered Rolan's Curse and Rolan's Curse 2? Those were made by NMK as well as their first foray into RPGs by Sammy.
