Well, if they really delivered "unparalleled compatibility", then people wouldn't be pissed about their Mega SG not running their new game. And they are pissed "whether you acknowledge it or not".
My point is very simple: it's clone hardware, they add compatibility after issues are reported by owners and acknowledge by them.
It's not the best platform for instantaneous compatibility (

They eventually fix the issues, but it takes time.
Also, I didn't see anyone here comparing them to big companies. Let's just not fantasize about what these devices actually are.
