It seems legally that the only way to legitimately have a rom is to rip it yourself. For example, I own 1943: Battle of Midway and Flying Shark arcade machines, but I would likely have to dump the roms myself to legally be able to play then via emulation.
I have ps1 and ps2 games that I have ripped the isos for, but I have c64, Atari, and nes games that I can’t dump without significant expense.
Cute naming schemes are for people who don’t have lots of servers. At my work we have over 700 servers. We’re not naming them after something arbitrary, we’re being descriptive.
