SM64/SMSR Multiplayer 1.4.2 + Dynamic Update

[Quasmok]

First of all, I recommend to play the game using controllers. Having your keyboard mapped to both players is a pain in the ass. You have a more restricted movement and also most keyboards mess up your controls since only a certain amount of button presses is registered at once.

Also here's the three things causing most trouble:
- Make sure you checked the "Controller is plugged in" box
- Make sure your deadzone isn't set too high. 0% should be fine. (Note that you might have to set it higher when playing with controller because the player would walk automatically - I had that with most XBOX 360 Controllers)
- Make sure your Range isn't set too low. 100% is recommended.



If any of that didn't help, try restarting the ROM immediately after changing your settings or just use a controller.
