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.
To play this game, patch the .ips file in the download link to a Pokemon Crystal (UE) v1.0 ROM using the tool 'Lunar IPS'. For a more detailed description of the hack, please follow this link: http://www.pokecommunity.com/showthread.php?t=350926
