No. Again these posts show how to add emulators for ones that show up in the dropdown list, not new ones. The emulators in your examples are already in the dropdown list of emulators. Example. I am trying to add Duckstation/Swanstation. When I enter the name either Duckstation or Swanstation or whatever they're calling it now, I add the file path to the exe file and hit Ok. I get a message telling me to enter a valid name and it erases everything. Just as someone else said.
