This is an unlocked version of the Dishonored freescroll macro, originally made by Som1se. All credit goes to them.

To use:

1. Download the macro, containing the .exe and .ini files.
2. Bind the action you want to mousewheel up/down ingame .
3. Modify the .ini file to specify which key will trigger your macro.
4. Run the program.

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?

Usually needs to be explicitly allowed by the moderators of the game. If you're not sure, ask! Also please check whether the game you're running has a limit on how many times a macro can fire the action per second. This can be modified in the .ini file.
