This looks promising... But as you know there are many GSC hacks out there... my advice is to mess around with the storyline a bit to make it more interesting...maybe change the gym leaders and probably the Evil Team cause TEAM ROCKET SUCKS... I guess that would spicen up the game.. other than that I like the snowy theme :D Good luck with everything... and hope this gets translated in english
EDIT: You didn't mention... is it a hack of EMERALD???
