How to choose the core during a Retroarch import process

[legolas119]

Hi,

i need to import again some Sega Megadrive games using a specific core of Retroach, and during the import process, LB doens't allow as it did before, to choose the Retroarch core i need to use for that game: as you can see, after chooing Retroarch, i can't select the core.

I need a custom core for a game (paprium) and the default sega genesis plus GX core for another genesis game. 

How i can import them correctly in LB?

thanks!

Just add the games as you are doing.
Then after u imported them, go to the game u want to run with a different core. Select "Edit", go to the "Emulation" tab, and enable "Use Custom Command-line Parameters".

-L "cores\custom_Core.dll

let me know how (or if) it works out

[legolas119]

yes, it works! 

Well, if i would like to import all my Sega Genesis games, using a default core, is it possible to set by default a specific core for all genesis game? Or is it necessary to to the action described above for every game?

thanks

yes. Well, u would just have a new platform called 'Sega Genesis'
And u would have an extra line in your retroarch emulator (associated platforms)

and for the sega genesis u would have the genesis core configured and set as default.

Anything that deviates from that for that specific platform, u would use the custom launch commands for.

If you have games in a single platform that use different cores, you will need to add the Custom Command-line parameter to the ones not using the default core for that platform (as described above).  One-by-one.

Alternately, for the games using the non-default core, you can (after importing) add the Custom Command-line parameter to them all-at-once using this plugin:

I see no real advantage to having all games in the same platform. Only disadvantages.
So best to separate games in their own platform.
saves time later on when u want to add games.
The custom launch commands should be exceptions within a specific platform/core
