[MAME only with 'Open With']

Its all about choice really, some people have multiple emulators for one system as some emus will run certain games better that others, so if adding a new emulator for a existing system suddenly changed the emulator for all your games in that platform then thats not a good way to handle it either. The "default" checkbox in the associated platform tab is used for all future imports for that system if checked, but it wont retroactively change what emulator is already set for that systems games.

Ahh, that makes sense. Thanks!

Sounds like that platform isnt associated with a emulator. Click on one of the games then use ctrl A to highlight all of the games in that platform, then right click one and go to edit, then click next and in the first dropdown pick emulator, and in the second pick your mame, finish out the wizard.

Also if you go to tools/manage emulators, double click mame and go to the associated platform tab make sue that the platform is listed there, and spelt exactly as it is in the left sidebar of Launchbox.

Thanks neil9000

 

So this solved my problem as well after having changed both Wii and 5200 from Retroarch cores to Full Dolphin and Kat5200.

My question is why was it necessary? I figured since I went in and changed the associated platform under emulators, that would change it for all.
