It is easy to learn but about 30 seconds slower. The problem is I can’t do it because I have weak fingers and can’t hold down buttons for more than a minute. Why must turbo buttons be banned? I can’t play without them

if it is 30s slower, why would anyone use it?

Maybe a beginner

what's the route

you still need to hold down turbo buttons. and I'm assuming its fire route

Using turbo functions could give an unfair advantage to those who play on original console with original controller. That's the basic baseline for many games. If you can't do it on original hardware, it's not allowed and it shouldn't really need more explanation than that.

Even if you used something like the nes max or nes advantage it's still considered a tool since the controller is automatically hitting the A button for you.
