Games in Platform Using Non-Default Emulator?

[Drybonz]

How do you assign an emulator (specifically RA core) that is not the default for that platform?  In other words, I want to place a game/games in my arcade platform, but have it run in Dolphin (core), for example, instead of MAME (RA MAME is the default).  I keep running into LB wanting to change the default for the whole platform instead of just assigning it to the single game.  Thanks for the help.

you can edit the game(s) you want to use a different core. Go into edit your Retroarch emulator in LB and in the "Emulation" tab check the box "Use Custom Command-line Parameters" and enter those accordingly. The only main difference would be you would want to load up the different libreto core rather than your default one.

specific example I have of the format. First is path to the emulator, then -L parameter is the path to the core, next is full path to ROM, followed by the fullscreen parameter.

D:\Arcade\Emulators\Retroarch\retroarch.exe -L D:\Arcade\Emulators\Retroarch\cores\snes9x_libretro.dll "D:\Arcade\ROMS\Super Nintendo Entertainment System\Contra III - The Alien Wars (USA).zip" -f

Thanks... I'll try it out.  We need a drop down box or something on that screen to change a per-game core.

*edit*  Actually, it looks like your command line worked with just the core part (-L D:\Arcade\Emulators\Retroarch\cores\snes9x_libretro.dll)
