Tyrion Cuthbert: Attorney of the Arcane on Steam
store.steampowered.com
In Tyrion Cuthbert: Attorney of the Arcane, you play as a defense attorney who practices law in a world of fantasy and wizards. You must defend clients accused of various crimes committed using magic and use the rules of magic to prove them innocent.

Just happened to come across this one on Steam, and the reviews are generally positive. Not expecting it to reach the best points of the best Ace Attorney games, but certainly seems to be worth a try.
