Original hardware is almost always better for authenticity as well as the intended pick up and play feel.
The issue is that it’s too expensive for most people to afford. I love my CRT and OG consoles, cartridges, discs, etc. but I’m well aware that such a setup is a luxury.
I’m convinced that old games feel “hard” because modern emulators have like 30 layers of abstraction between the input and the screen.
Today you’ve got controllers going through bluetooth driver stacks, on general purpose operating systems, with all sorts of thread coordination, GPU APIs, not to mention display latency…
Much easier for the brain to learn when the original hardware is extremely deterministic!
