Portables all over the place.

SNK's main games of focus were SNK vs Capcom for the NeoGeoPocket Color, and Koudelka. Most of SNK's booth were infested with their portable machines. Koudelka was not playable, and only a theater of the game which showed nothing but movie scenes (no battle screens) were present, and while visitors to the Koudelka theater were given demo CDs, the demo too only included the movie. 
 
 

All new characters, 20 years later.

 
However, one unexpected game was present at SNK's booth: their latest Samurai Shodown game, dedicated to the Playstation. < Select Screen >  The base of the game uses the same engine from the Samurai Shodown 3D series, but with all new characters.
