Now I feel so bad for u I'm looking up stealth gaming systems lol. I dont know if they exist but I was thinking a console that has had its outer frame removed and 3d printwd a random older systems case for it... so in other words will the know a raspreberri pi from a gameboy if the outside is using a ganeboy cover and maybe a gameboy startup screen? U could even hide the OS to a degree or at least mask it. Otherwise ur literally limited to pre nintendo ds days. Which for me is not bad as I actually prefer the games from the 80s and 90s anyway.... but I don't know what ur taste is either.

I mean as a cyber security engineer I find it mad that they don't just implement some security changes to prevent people connecting to the WiFi and have a separate guest access for non Corp users... but hey I get it. They're assholes.
