Another great thread.
I had Sonic 2 on Game Gear, but I never beat it... Hell I rarely ever got past the first Zone... Because of this asshole you mentioned!
People who didn't play it may think "some boss later in the game that's hard to beat?"
No, it's the first FRIGGING BOSS. And the reasoning is everything you explained about the GameGear limitations.
... ugh... ptsd.
Thank you
Shame the Game Gear's issues made what should be a decent boss into an nightmare-inducing battle for Sonic X(.
