Retroflag has recently released a controller accessory for the Nintendo Switch that creates the look of a portable Gamecube. This is a single piece, designed to use the Switch and OLED Switch in portable mode (not a separate controller). While I haven’t testing this personally, Retroflag’s Genesis and SNES USB controllers had some of the lowest latency ever tested, perform fine and are a great price – Let’s hope these are in the same league:

Update (Thanks Ed!): One thing to note, is you need to make sure your Switch has wired connections enabled for Pro controllers, otherwise it won’t work.
It’s fun to see things mass-manufactured that were obviously inspired by the retro community! Hopefully more companies will ‘take inspiration’ like RetroFlag, as opposed to outright cloning like we’ve seen in the past few years…
