Creating an emulator core exception for a single game via Retroarch

[Bedwyr]

This is evading my search-fu so I'll put a question in the noobs forum.

I want to create a core exception for a single game. That is, I still want to use retroarch for this one game, but load an alternative core. Currently, when I edit the game, I can still select Retroarch, but the standard emulator dialogue loads and I'm afraid of making changes that would propagate across all games of the same platform. How do I load a unique core just this once?

Edit the game then go to the Emulation tab and check the box Use Custom Command Line Parameter and enter the following as an example but switch out the mesen dll for the core you want to use.

-L "cores\mesen_libretro.dll"

Will this also work with other emulators? F.ex. I wanna use ReDream for certain DC games, but usually I’m using Dolphin, as not every game runs in ReDream.

All you need to do is edit the game. Go to the Emulation tab and change to emulator to the one you want to use. That specific game will then only use that emulator you linked to it.

Since when does Dolphin play Dreamcast games ?
