Master System Region Free?

Yeah that's about the extent of it. Sad to say.
Master System isn't as import friendly as popular belief suggests.

There's neither proven working pin converters to play Japan-size carts on western models, or a known mod to get Japanese models to use the western region setting (dual language games should always display their Japanese content on a Japan model).

Whee I left some words out. That was supposed to say something more like "just with any speed differences if they only released the game in a 50 Hz country and you're playing them on our 60 Hz systems."

True... I wouldn't be surprised if there's games we may never know the intended speed. Not like devs from back then are just going to pop back up and comment on 50/60hz differences. If they can even remember details that specific after working on potentially numerous other games over the years.
