NeoGeo Cup '98 was released in May 1998. It was actually a hack of "Super Sidekicks 3" made by SNK themselves. His subtitle is a homage for "Fatal Fury 3 - Road to the Final Victory"
A serious bug: Using a USA bios rom if you insert a coin on the 'winners don't use drugs' screen on a single slot the games will use the neogeo bios s1 tileset rather than the game tiles, this causes most of the graphics to be hidden and the games to be unplayable, it will also end up using the mainboard z80 bios so sound will be broken, the games should fix themselves if you let them run another attract loop after gameover, on a multi-slot the games will reset. This is one of the first 4 'gigapower' games, the bug was fixed after that.
