Not a Switch owner, but it's worth noting the PC Virtua Stick I mentioned was released by SLS roughly alongside their Saturn pads, so they might share some common internals. The SLS stick works on PS4 via a Brook PS3-to-PS4 converter, so it's quite possible the pads would work on Switch via their PS3/4-to-Switch converter. They're not listed among the compatible devices, but neither was the stick in my case -- and the stick's default button mapping suggests the converter was intentionally programmed to support it.
