Hello!
I have installed the game with TeknoParrot and patched it with the shader fix. Everything perfect, except that the aiming is miscalibrated.
I have put the HOTD4_MouseFix.exe in the / elf directory and run before the game, but it doesn't detect the TeknoParrot and it doesn't fire at all.
I have to recheck the "Use Mouse for gun", so I continue with the problem of targeting failure.
