I considered this when adding the triforce branch of Dolphin itself to Batocera, but it’s just a bit silly to have a specific version of the emulator for each game you want to play.
Unless someone can make a version of Dolphin Triforce which can play all the games (even if they do require gecko codes or whatever to function), it’s not likely going to be included in Batocera.
At least for now, you can play the two games that are not playable as home console versions.
