NGM-258 remains a mystery. We do however have several logical possibilities for which
game SNK may have intended it to be. None of them have been confirmed. NGM-258, a circa
2000 spot in the catalog, occupies the absolute youngest undiscovered position on the list.
Based on the fact that we have no visual proof of Last Blade 3, and the fact that Dance
Rhyth Mix was most likely a utility cartridge, the most accepted theory for NGM-258 is Garou 2.
THE FOUR PROSPECTS:
--(01)-- Garou Mark of the Wolves Special
SNK may have been working on Garou 2 (Fatal Fury 9) before pulling the plug on software
development. If so, it would be the most sought after unreleased NEOGEO proto of them all.
The two screen shots clearly show a MotW character (Marco Rodriguez) fighting Mr. Karate
(an Art of Fighting boss) with a beach-like background, neither of which were in the first MotW game!
--(02)-- The Last Blade 3
SNK may have been working on Last Blade 3. However, we do not have any screenshots or
any evidence whatsoever to support this claim; other then some trade industry discussion
from back in the day. It therefore seems highly unlikely that Last Blade 3 is NGM-258.
--(03)-- Dance Rhyth Mix
ADK's last NEOGEO release was Twinkle Star Sprites in 1996. And the Bemani craze didn't
begin until 1998. And NGM-258 is from the year 2000. However, at some point in time, ADK
apparently developed a NEOGEO dance themed game. (Reported September 30, 2003)
--(04)-- SNK VS. CAPCOM
Although released in 2003, an earlier beta of this game may have been developed in 2000.
