Change Emulator For All Rom Files

[Spike Jabber]

I recently changed my arcade emulator from RetroArch to MAME.  I have already done a bulk edit of all the games, but it only changes the main rom for each game.  I would like to edit the emulator on every game and rom file associated with each game.  Is this possible?  Thank you.

Only manually your best bet would be to delete all the games from the platform and reimport them using MAME instead this way all the additional apps would then work with MAME and not RA. Sorry that its like that bulk editing Additional Apps has been requested in the past but still hasn't been added so for now that is your best bet.
