Using different RA cores for same system

[Joe35car]

So say I have Nintendo DS all working in launchbox using retroarch core melonds ds. How would I change say a game in that system to use a different core?

Most common way is likely using the custom launch parameters. Edit the game and go to the launching > emulation section and toggle on using custom command line. you enter can enter the command for the preferred different core in it.

Another way would be to setup another emulator instance in your emulator list for Retroarch but this time select a different core in the associated platforms list. then you assign this different instance of Retroarch as the emulator for that game.

You can also add more cores for a platform on a single instance of Retroarch in the associated platform list, but it wouldn't choose that one each time by hitting the play button like normal. It would require right click play with to select the intended different core or using the game details screen then play with if within Big Box.

A few choices to suit different use cases
