Definitely the NES for me. I was an arcade boy ever since I played Pac-Man in 1980 but no home games - console or computer- interested me beyond maybe an afternoon at a friend's house until I saw the NES. The hardware and the controller were just so much better than any console before it, with scrolling backgrounds and fantastic music that allowed game design to evolve to the point that home gaming became solidified as a permanent form of entertainment. Games like Super Mario Bros, Metroid and The Legend of Zelda had never been done before, anywhere; addictive, arcade-type gameplay mixed with deep worlds and level designs that became staples in the industry and later games like Mike Tyson's Punch Out and Super Mario Bros 3 just looked and played good to the point of disbelief at the time. That's before even mentioning all of the 3rd party games that helped to define the system: The Castlevanias, Mega Mans, Ninja Gaidens, sports titles... the list goes on and on. And so many still play beautifully today, with anyone able to pick up and play these classics so easily.

The NES, SNES and Switch are my 3 favorite systems of all time, and I can make a case for any of them to be number one. But the NES changed the industry more than any home console before or since, in my opinion.

Gen 7 - PSP Go.

Still bring it with me time to time as it's a true portable that fits in my pocket. It's modded so I play SNES roms/PSX/PSP games on it.

The oldest platform I still use is Wii (technically, on Wii U because I did the stupid thing of transferring my data).
The Virtual Console has some games that aren't on Switch - Chrono Trigger is the one I play the most on the Wii.

8th gen - Switch 1 (OLED)


Its my travel/portable Switch which I use to play third party multiplat titles I own on Switch

Aside from that I'm 100% on Switch 2, PS5, Xbox Series X , iOS and PC.

I’ve got a lot of legacy systems at my fingertips, but with NSO, backward compatibility, and so many retro collections available, there are fewer and fewer reasons to plug them in.

Right now, the only systems I use regularly are Switch 2 and PS5. I might plug in the GCN for a round of Monkey Target if friends are over, and I do plan to replay a bunch of Wii games over the next 17 months to prep for the 20th anniversary next year, but those systems are not in regular rotation.

Now, if you're talking about the earliest generation of games I play regularly. That's the 8-bit generation. I play NES/GB games on and off all the time still - in the last 2 years or so, Captain Skyhawk, Cobra Triangle, Metroid, Final Fantasy Saga/Legend 2, Mystic Quest/Adventure of Mana, Dragon Quest 1-3, Final Fantasy 2 (FF1-3 in the past 3), and Super Mario Bros 3.

I've been digging up my Master System every december.
Though that's about to change as my last CRT TV is just about to become unusable as TV (with digital converter box) as Finland moves to HD only. So I'll set it with SMS for permanently available use (as is my semi-working PS2 with another old TV).

It's hard to say what would I have emulated in any regular way. I've played little bit all kinds of old stuff, but not even NES so much that it really counts, so SMS could be said to be also the oldest thing I've emulated enough to count.

Just two days ago I booted my Wii U up again to play more Fatal Frame V using the Gamepad as the Camera Obscura like Hylia intended.

PS3 because I can use it to play PS3, PS2, and PS1 games.

My two Game&Watch

What Gen are those, anyway?
