I always felt that the idea of spoofing the game carts through the cart commands would be the first attempt at a flash cart of sorts. Porting the usual 3ds commands and "replying" as if it was a legit game cart but that would all be at a hard-ware basis and only be enabled for one game cart at a time with no sort of riced up menu of sorts like DS flash carts due since people are unable to run their own code.
Seems fake though, from everything else I've seen surrounding this.
