There was apparently a CGTP-8 (Wii U, not Switch) that was being made a long time ago, but they cancelled it shortly. :/

Wait, really? Shame it got cancelled...
CTGP Deluxe broke due to version 3.0.4 on the game, I really hope they find a way to ressurect it.
i just modded mario kart 8 and downloaded a delux mod that dosent even work. i wish there were a mod like the cancelledone for 8 :<
