And I found out Sonic the Hedgehog 3 is region locked, meaning it will only work with specific region systems, I only own a Japanese Mega Drive and Sega Nomad (which was only released in America so the region is American) but sonic 3 with Sonic and Knuckles will work on any region system, now I’m gonna find out if you can mix them, the Pal Copy with an American Lock-On it will either boot up into Sonic 3 and Knuckles or give me the No Way screen. Let me find out in some time, also I like the box art.
