Best bet would be to create shortcuts for all the games exes and import them like roms when it ask for an emulator point it to any existing emulator you already have added in LB then finish the import after go to your Windows platform and hit ctl+a to select all your games the use ctrl+e to open the bulk edit wizard from here choose emulator from the dropdown and in the 2nd dropdown leave the value blank and not of those games will be associated to an emulator any longer and the shortcuts should launch just like the exe would
