So, I've gone back to the Legacy version of Cuphead by Right Clicking on Cuphead in Library-> Properties-> Betas-> legacy -no patches --use at your own risk. I can see [legacy] next to Cuphead in my games library. So I'm guessing I've done things right. Right?
However, the weapons switch glitch won't work for me. I've have Peashooter and Roundabout equipped, and keep LB pressed. But the Weapons won't switch like they do for speedrunners.
What am I doing wrong, and how can I get the Weapons Switch Glitch Back?
I've even tried downpatching using the Steam Console. The glitch won't work that way either.
