Don’t think this is gonna be a 100% Gold Remake, it’ll have its differences. Extra battles (some’ll be optionals, tough but rewarding), Hoenn Pokemon (in every area, and hard to find) New areas, Remapped some dungeons (so your old guides wont work) , Extra recurring characters (some’ll hate you, some’ll help you)
Note that the hack is incomplete but feel free to enjoy the hack as-is.
Dr Mario (2 Players Inverse Hack). In the original game mode, two players the color and location of the same virus. The hack in two-player mode the location of the virus is the same, but different colors. Initially, the players are in different conditions.
