PS1 games not responding to inputs
The two games I am seeing the issue with are Tekken (no response from input at all) and R4 - Ridge Racer Type 4 (can't steer when in a race).
The issue is most likely related to what I am assuming is the PCSX-Rearmed controller one being DualShock, when you can only set keyboard inputs for digital controls.
Potential Solutions: A switcher to set different control types (standard/analog/DualShock/etc) or ability to set X/Y axis of analog sticks to keys.
