A much simpler fix I discovered with some trial & error, for those not wanting to use any scripts. Just make sure you've configured emulator settings, your controllers, etc. first. Step 1: Open Citra-QT and make sure that View > Fullscreen is checked. Close the emulator if you wish. Step 2: Navigate in File Explorer to C:\Users\(your username)\AppData\Roaming\Citra\config Step 3: Right-click the qt-config.ini file, go to Properties, and then check the "Read-only" box and click OK. No need for scripts! Since exiting a fullscreen game requires leaving fullscreen first, the qt-config.ini file was changing Fullscreen to false. Setting permissions to read-only prevents the file from being modified, thus preserving the fullscreen=true setting. Note: You may need to perform these steps again after an emulator update, as it may overwrite the permissions and/or the file contents of qt-config.ini.
