When it comes to anything 8 bit and 16 bit, i like to have a physical copy but i still play the game on an emulator.
I use an original xbox to play these games and only restrict myself to a selection of everything that I own. To me it gives me a better experience because i can output these games full screen in 720p resolution.
Sometimes i think that this might be weird to some because some might think it defeats the purpose of collecting games because they just sit on a shelf. But then you have people who collect stamps and coins and they sit in boxes and drawers.
