Thank you! I'll give that a try. Just to confirm, the idea is to bind, for instance, L2 to the left/right keys of the keyboard?

Is there a quick guide for setting up DIC on a PS4 controller?

I've tried many settings and it doesn't split for me as well. I'm using - [GCDJ08] [JP] Biohazard: Code: Veronica Kanzenban
