Where is the Wolf3d core for LAKKA

I wanted to ask a simple question why isn’t the wolf3d core isnt included in the Lakka build of retroarch? The reason why I asked is I wanted to play some wolftenstein 3d but instead I had to use the dos core for the game and I dont like it because I prefer to play via controller and yes its a pc game for some players it is the way to go. Im looking forward to see your response.
