I don't believe this is actually true for many consoles. Game Dev Kits where normally a more open version of the hardware that was either hard coupled with a PC, or able to connect to one and have game data essentially streamed too it. See this video for an example; https://www.youtube.com/watch?v=GH94fKtGr0M https://www.youtube.com/watch?v=GH94fKtGr0M Not that I'm trying to discourage developing for emulators. Just see how machine accurate the emulator you're using is first :)
