Couldn't muster any info on the topic of how to set the region of a GG either.

If I'm not mistaken someone on this very forum spoke of Ristar or some similar adventure game that had an entire game section missing unless you ran the cart on a JP GG.

Other carts are likely equipped in the same manner some Mega Drive carts were, detecting the region of the console and loading the ROM content accordingly. I wouldn't be surprised if the GG Bare Knuckle games also do this.
So I could just buy the JP version of Tails Adventure and its basically the same as the US one I owned as a kid? Okay, glad I know this....

Also one game I recall being affected by regions was, of all things, a Puyo Puyo game that never got localized, but if played on a US GG it has an alternate title screen calling it something like Wizard Kids or something, and english text. Which some speculate means it was meant to be released stateside and it just didn't happen for some reason.
