Hey, TotoMud. I have got an idea to improve Dark Forces the Game.
My idea that Costali was joining the Pokepals to defeat the Dark Forces, afterwards, he returns to his trainer without quitting the guild, Which happens to be Dawn of Twinleaf Town, which is according to the Dark Clone storyline, is defeating Giratina and Shade Mew in Zintoh, which means that if a player sucessfully finishes the game and gave me a .sgm file, an IPS patch is applied to Shade Mew (game) allowing you to obtain Costali at Shade Mew, which is an abnormal Riolu that can learn Aura Sphere. And the last game of the Dark Clone focuses on Darkrai so if Costali was traded to the game Darkrai will say 'Th...This is the Pokepals' Riolu!' and Darkrai becomes Rageous and is level 70 instead of 50, but you have at least a point, Cresselia will join you in this battle.
