A macro for Dishonored 2 (and since then also Dishonored: Death of the Outsider and Dishonored 1), that allows you to bunnyhop without a freescroll mouse.

To use:

1. Run the program.
2. Bind wheel down to jump in game. (You can still keep the default spacebar bind.)
3. Hold space.

Dish2Macro.ini

If you don't like using space you can change it in Dish2Macro.ini to a different key.

You can also spam wheel up instead, or set up separate keys for each scroll wheel direction.

See that file for an information on how to configure the macro.

Is this allowed in speedruns?

Yes.

Specifically any of the Dishonored games allow it.
