I have Steam updated and also Zaccaria Pinball with its latest table, I have followed many tutorials but I can't get the launcher to work, if I put the parameters as you show and the latest version of pinballX that already has Zaccarpia Pinball included, it doesn't work, a black screen, if I delete the parameters Zaccaria starts without a problem but starting with the players that had played the last time, let's say that the launcher omits the number of players and game modes
It seems that there are more people like this but I can't find a solution, I have even tried it on my laptop but even then I can't get it to work to choose the game mode
