You don’t need ancient firmware. The latest hackable firmware is 7.55 which was current roughly a year ago I believe. It’s not hard to get consoles with an exploitable version.

I think the answer is 120, but I'm not sure. 3*4*5 = 60. 60^60 would be least divisible and least rooted by 2,3,4,5 in this way.

I think just the cat part of the cafe is closed. The article says, “Now it’s just a regular cafe.” There’s actually a divider that separates where the cats are kept from where the food is served due to sanitary laws.
