MiSTer is a great option for high accuracy and zero/low latancy emulation. And besides being able to use original controllers you can also drive an analog display with an analog IO board, if that’s desirable to you.
If you want real hardware, this isn’t it. And I can understand wanting the real hardware. But for a nearly perfect recreation of the experience without the headaches of maintaining aging hardware, MiSTer does the job.
Analog Pocket looks cool too. But wanted to nerd out on the MiSTer specifically.
