I mean the HAS is great at it is, I own 3, but this kind of thing and adding something like an esp32 chip could lead to a lot of cool software features (which could/should be open-sourced, I'm not asking to put in that side of the work, just adding ressources to have a built in webserver in // to setup stuff (like the esp32 does)
this could mean selecting a game profile on a webapp, and it would auto select a saved controller layout, turbo layout, if sounds needs to be reversed (bootlegs, sorcer striker/mahō daisakusen, others) tell the RT4K to select the right profile (and vertical or horizontal layout info for rotation)
I really mean just opening it more for options and to interconnect with other devices
