Basic controller support thing, based on Antimicro (Keyboard emulator for gamepads).

I wanted to replay Stalker with gamepad, but there is no assurance, that GSC wil release update for original trilogy in near future, so decided to use improvised tools. Part of actions using the same buttons with holding mode (you need to hold button to make action)

Limitations of method:
There is no aim assist ingame and it may be difficult to aim with gamepad, so I tried compensate it trough config - mouse speed slows down to 50% when you press Left Trigger.
I can't predict which modification are you using, so there is no button promts ingame for gamepad.

Also I played with casual config edit for faster health regen.

1. Download and install Antimicro
2. Download this profile
