Shut up! SHUT UP! SHUT UUUUUP!!! :matt-jokerfied:
Just get a fucking rom!!! Go to Google and you can have the game on your hard drive in 5 minutes! Chances are your "incredibly rare" cult classic is playable with a high degree of accuracy. Even if you dislike emulation, you can just burn a disc, put the game on internal storage or use an Evercart depending on the system.
We don't have to pretend we need to hunt down decades-old pieces plastic to access old video games. What's that? Kuon for PS2 is really rare and expensive? Well I'm going to go download it right now to spite your collector brainworms... AND IT WILL BE 100% FREE OF CHARGE
I just like playing them on the classic hardware if I can. There's a big market where I live for bootleg versions of old consoles that are basically emulators anyway. I have two for the PS1 and Sega Dreamcast.
