Since the hardware is segregated, we want to create a new category with DLC.

And I don't think there is a clear prohibition in the rules about the use of DLC, so you should make improvements.

How about adding Ghost Road All Stages Clear Speed Run and Ghost Road 1 Stage Clear Speed Run for the casino to the subcategories? I tried to clear all the stages to see if I could do it, but it was 47:11. It is short, but I thought it might be interesting. Please consider it.
