iq_132 ported the Samurai Nihon-Ichi driver, which is sort of a Taito/Kaneko licensed games of sort.
The games are very obscure - I'd never heard of them until last night - but they're really quite fun to play and have that oldschool mid-80s Japanese vibe.
These 2 really stand out (IMO):
Samurai Nihon-Ichi - If you like Kung-Fu Master, you'll love this.
Go Go mr. Yamaguchi - Kinda like Penguin Adventure on MSX, but you're one of those 'round the world explorer type guys.
Lady Master of Kung Fu - Kick some ass, 80's style. Yea, I don't have a better description/comparison for this one..
