Why there are no xbox one and ps consoles to select?

probably if we had an emulators section I think this game would have a lot more runners considering how hard it must be to find a copy of the game and also have one of those old consoles

hello everyone, i want to start making sonic generations speedruns and i was wondering if it is mandatory to use an rta timer because i play on my xbox one and i dont know how i could put one since i dont have one pc in my house
