I totally agreed, I rather play the original console like Super Nintendo, Sega saturn and others console, just to get a feel of a real nostalgia to it. Unfortunate I often worry that my console could breakdown one day. Playing classic games on emulator software doesn't alway feels right though and that is what put me off. Playing latest PC games on Powerful machine rig which I feel that doesn't belong to there or does not feel right. I always has been a console user.
I often find it funny how people who like pixel art dont get that old sprite based games didnt look like that at all and lack the clean cut edges of 'shopped stuff they see on tumblr
They probably like that indie fake 8-bit shit with modern lighting and other stuff that real 8-bit systems definitely couldn't do.
The Right emulator with a good converter works fine for me. I have a Genesis to USB Converter which works great. Still I'd rather have shelves full of Carts than a disc full of roms.
