When it ask for an emulator you can put in any emulator or you can create a dummy text file then change the name to whatever you want to call it. If you choose an emulator you are already using you will have to edit the platform by using ctrl+a to select all games and then ctl+e to edit them this will open the bulk edit wizard from the drop down choose emulator and then leave it blank this will make the emulator to null and then if you are using .exe or shortcuts they will both launch. If you go with the dummy emulator it is simply an empty text file that won't do anything and the exe or shortcut should just run
