Are there any restrictions on emulator usage? How about controllers?

Since there were no other players besides myself so far, I had not considered this, but I would like to make it a rule that when using an emulator, anything that cannot be done on the actual FC/NES is prohibited.

Using savestates is not allowed. Rewinding is not allowed. Altering the game speed is not allowed.

As for the use of the controller, I would like to prohibit the use of turbo/auto-fire.
