To my knowledge this is the only Neo cabinet I have ever seen with dedicated art all over the cab. I have know about the SamSho II one since way back when they released it but never seen one in the wild. All other "dedicated" Neo cabs I have seen (made by SNK) have been Big Red cabs with the main Marquee replaced with one game title art. They made quite a selection of large Marquee art inserts for the Big Red cabs.
Aside from unique projects like Irritating Maze, I assume SNK sidestepped the full cabinet art/design approach to keep the game switching process as cheap and manageable as possible. Simply switching the cart and marquee card was their primary draw (aside from the multi-cart capability of course) for arcade operators.
Samurai Shodown II was a very special case since it was their best selling game worldwide by a long shot and was probably their biggest title to rival the likes of Mortal Kombat and Street Fighter 2 in the western/global arcade market at the time.
Although the original Samurai Shodown was ported to a ton of home consoles, sadly, Samurai Shodown II never received that wide of a distribution for home console users of the 90’s. The ports of SS1 were compromised, but with some adjustments and improvements I bet Takara could have pulled off some impressive ports that could have elevated the success of Samurai Shodown II even further.
Samurai Shodown II was SNK’s best shot at international success at the time. The unique cabinet art treatment of this title only helps to cement that status imho.
