Double Speed in game (Pokemon)?

Good morning and sorry for my bad English.

First of all I would like to congratulate the creators of CITRA. My question:

Is it possible to increase speed in the game?

Example: the SPEED button exists with Drastic or Myboy.
So I’m not talking about CITRA speed, CITRA speed is OK.

Thank you and great work

ctrl z will speed up citra to however fast your computer can handle
