so i was wondering why it does that slow down thing when i started the level? it does this in random spots in other parts of other levels, i have re-plugged in my controller, i have plugged it in a different USB port, i have reset my key binds for it multiple times, i have done about everything, and i can guarantee that i did not let go of the sprint button what so ever, i had the controller set on my desk and used 2 fingers to hold it down to make sure it doesn't go up, plz help

I don't think Mesen is allowed anyways.

it is, i've showed it in runs before, and they seemed fine with it

Try to find a more accurate emulator. Like bizhawk or fceux. The emu you may be using could be doing something to the inputs that's slowing you down.

alright ill look into it, it didn't use to do this, it just all of a sudden started doing it

I use FCEUX for TASes and Nestopia for RTA runs. Never had a problem with them. Bizhawk works too, but I really don't recommend that.
