I had a look for that game - seems interesting. Couldn't find a ROM dump for it anywhere, though at least one site claims its a "work in progress". I don't think the NeoGeo is still being produced is it?
Finally managed to track down Kensai for PS1 a few weeks ago - the aikido in it is disapointing. Mr Segal's character does 1
(and one only) aikido move (irimi), but it's sweet!!
Hopefully the guys over at http://www.ugfighting.de.vu/
will get things right
