Really miss not playing old ps1 games

Since my parents never owned a TV and weren't fond of me playing video games, I never owned any console (and obviously I was the only kid without a gameboy xD).
Only in 2009 me and my brother put all our hardly earned money (we didn't have pocket money either.) from years of gathering together, plus some coupons, to get a Nintendo DSi for both of us.
As for the games, I bought several to a friend of mine for a few Euros and once managed to get my grandma go buy me Mariokart DS for my birthday.

TL;DR: I've owned a Nintendo DSi.

I've had the Magnavox Odyssey 2 and a Colecovision.

That's it. All PC since.

Nintendo 64
PS1
Gamecube
Gameboy (Color, SP, DS)
Wii
PS2
PS3
PS4
XBOX 360

Nintendo 64 will always be my most nostalgic but I really loved the Gamecube a lot, even if it wasn't very popular. I'm going to be getting a Switch this month so hopefully it'll be as fun as the old Nintendo consoles used to be.

Do emulators count?

Might seem like i'm quite loyal to Nintendo, but in reality it's just because so many of the Xbox/PS games end up on PC that I've not really seen a reason to buy one of those consoles, while with Nintendo,you get more "unique" games, and many of them are good for couch multiplayer.
