Originally launched in 1992, Shuffle Fight is part of Banpresto's Compati Hero series, and features figures from series like Mobile Suit Gundam, Muteki Koujin Daitarn 3, Heavy Metal L-Gaim, Mazinger Z, and Getter Robo, among others.
The game is divided into two modes — a campaign and a "war mode" — with the story joining the Super Robots in their fight against Emperor Darkus of the Zakbaran Empire, who is on a quest to steal Planet Cardian's mystical "Card Metal".
Its gameplay, meanwhile, consists of creating units and maneuvering them around the board to capture your opponent's base, which is done by initiating battles with enemy units and playing different cards representing your available mecha and items.
This recent patch is the work of BlackPaladin and Longsun Zhao, alongside a bunch of other individuals who helped out with the Dual-Tile Encoding routines.
