Good call out! The touch screen is generally pretty unpleasant to me now as well.

Wii and some Wii U stuff too, there's a whole era of games on Nintendo platforms where devs felt it was necessary to use input or display gimmicks. Once in a while it was essential to a game, but frequently it was shoehorned into an otherwise pretty traditional game.

Some of that could be fixed by smaller scale mods or cheat codes, but you're right that some might take big changes that need a decomp.
