GP2040-based means it was super easy to set up for Nintendo Switch Online Virtual Boy!
Took me like five minutes to reconfigure the buttons to be Switch-friendly and I got it working on my NSO Virtual Boy. Honestly an OG controller somehow feels even better than the N64 controller for the VB library (minus Hyper Fighting, of course)

The greatest controller upgrade in existence.
This turned my broken Retro-Bit saturn controller into one of the most solid I've ever used. I immediately grabbed the things I need for the NES and SNES versions directly afterwards. I highly recommend these boards even if you don't own a Mister, very simple to install and you won't regret it.
Hoping for N64 or PS1 Dualshock soon!
