Basically, you'd have to start from scratch to make it run smooth on the Wii. Furthermore, if you'd want to have custom quests on the wii utilizing this 'homebrew ZC.' You'd have to program this version to accomodate all the features each of the quests you're porting over are using. Its just too many variables and nobody really has time as it is to do that type of workload. I mean, look at ZC 2.5, its like Duke Nukem Forever at this point. So why push the devs to start a new project to get ZC on the Wii? Its pointless.
