Game Input MultipleXer

Hi,
I finally could connect my g25 to my ps4. Thanks Matlo for great work!!! I moved to windows10x64 which made everything easier for me.
I tried to test gimx for the first time with DIRT, but to launch the game I need to map the OPTION button. I cannot. I have mapped every other button and it seems to work except this one, which is crucial.
Anyone has experienced the same thing? Any solution for this?
Matlo, I attach the modified config file + log, maybe you can suggest something.

Hope to get some help.
I would also appreciate if anyone can confirm if in PROJECT CARS the button OPTION is needed.
Rgds.
EDIT: I tried another game (Unchartered 3) and same problem happens. This time with "x" (cross). I need to press x to enter the game. It is not working only here, since x works anywhere else.

Hi is dirt rally the ful game or a demo

Hi, Dirt is the demo. But Unchartered is the full game.

Hi I had this with a demo try plugging in an other ps4 controller into the ps4
It will work fine with the full game

Hi, Thx for support!
You mean having my G25 connected to PS4 via PC-Gimx-DS4 (as described by Matlo) and also another DS4 just connected direct to PS4?

Hi, just got everything working.
I bought project cars and it works. I only played for 2 hours, but I can race now!
Some disconnects when changing cars, but easily solved reloading the circuit again.
The problem with DIRT was the demo itself not gimx.
Mapping needs to be done for g25 almost for every controller function.
Thx Matlo!
Rgds.
