virtual controller issue with non unity games

[BThiebaut]

I'm trying running the model in some different game to see what happen for fun.
In unity based game it's working, well mostly enjoying licking the walls or watching the sky but at least the inputs are actually well sent to the games.

But I've tried with the binding of isaac: rebirth as it's showing in the paper as an case example, I start the game and go into a game, then run the play script and all output on the shell window seem correct, but the game don't reply to the virtual controller at all.

(.venv) PS D:\workspace\python\NitroGen> python scripts\play.py --process "isaac-ng.exe"

I'm running the game trough Steam, tried to disable steam input or even force it on, it won't change anything.
The game process window seem to be well hooked as I have the fps slow down that let me think it's working.

I'm wondering how you guys managed to get the virtual gamepad input working for this particular game, do you have any clue ?
