Imo emulators are bad, they have tons issues and glitches. I rather play games on original hardware with original controllers, and these consoles do look good on your tv with the right cables and equippment
And yes you can also pirate on original hardware if you know how to mod
Nor the hardware or the DVDs are that safe against the test of time. I once bought an old PS2 with Shadow of the Colossus. The machine was pretty old, but I cleaned its insides as best as I could. The first time I'm playing SotC, and imagine my surprise when the game kept glitching out: the ground dissapeared a couple of times, some of the textures became green, others became oversimplified... Always hearing about how much of a masterpiece the game was, and I was fighting to travel around in the overworld without any ground! The console was too old, and it died months after I beat the game. The last thing I played on the machine was the first level of God of War, and it looked and sounded like a bad creepypasta: enemies deformed, colours and textures altered, music distorted... then the console died and was unable to repair it. Now I emulate PS2.
