I tried setting up the nfc as "@PC/Stardew Valley", for example
I also tried the direct path suggested by the app :
"/userdata/roms/ports/Stardew Valley.sh"
Those two methods result in the behavior I described (as if Batocera is still in the main focus, and the game isn't really launched correctly via emulationstation)
I also tried an explicit zapscript command "launch:ports/userdata/roms/ports/Stardew Valley.sh" but it does not work

It depends on how the game was defined within ES.

Hello everyone,
I'm having trouble setting up Zaparoo to work with native linux ports :
I installed Zaparoo within Batocera v42 with the system update, it works perfectly
It also detects correctly the nfc card reader I have plugged in
however, the method of launching a native linux game is weird
Within Batocera, when I click on the .sh of the game,I have a batocera spashscreen coming up and then the game launches
With Zaparoo, I never got the splashscreen, even if the game launches in the end
BUT (this is where it gets weird) :
Once the game is opened, it behaves like it's on background, even though it displays perfectly on the screen : If I click on a button on my controller, it will launch the game focused in Batocera, in the background (while the original game launched with Zaparoo il still running)
I have the feeling I could completely navigate within Batocera, blindly, and go wherever until I launch another game that takes the focus

I set up my .sh scripts per the Batocera wiki
Essentially, every game I own is from GoG and I launch them using this kind of .sh script in Batocera :
#!/bin/bash
cd /userdata/roms/ports/.data/Celeste && export DISPLAY=:0.0; ./Celeste
(Celeste is taken as an example, but I mainly tried with Stardew Valley)
