Background starting a game

[sonkers]

Hi!

Is there any way when I select a game and I want to put something in front while the game starts in the background?
Example:

I want to put an image when the game starts while this image stays for like 5 seconds, meanwhile in the background the rom starts like rocket launch

tks.

use rocketlauncher
executable = RocketLauncher\RocketLauncher.exe
arguments = -s "%ITEM_COLLECTION_NAME%" -r "%ITEM_FILEPATH%" -p "%RETROFE_EXEC_PATH%" RetroFE -f
