This was very needed. They should make 2 default controller schemes while they're at it, "Standard" and "Recommended."
"Standard" as it is now. "Recommended" being a control-style that actually makes sense with today's controllers, which varies by game. For example, F-Zero X had some confusing shit where you had to press the L button instead of ZL to turn, but the regular R button was fine? Star Fox 64 may have been the same way. And don't get me started for Goldeneye 007/Perfect Dark, I think I spent more time trying to set the buttons than actually playing it.
I just decided over time to not bother with the N64 offerings.
