That was it! Thanks so much

I've looked everywhere but I cannot find info on how to set a standard Retroarch emulator for one single ROM (in this case, an N64 game using Retroarch loaded with Parallel64) that is different from the default Retroarch cores/emus (default N64 emu is Retroarch loaded with Mupen64). I can right click -> "launch with" -> then choose one of the 2 but when I simply click "Play" to play the game, I would like to skip that step. Massive karma and much thanks for any direction here! :)
