I know that the main world in Minecraft for XBox is limited to 1024 x 1024. I have heard that the Nether in this version has a permanent wall of bedrock around it, so it also has a fixed size. But how big is it?
Also, if the Nether is 1024x1024, how does the faster travel work? For example on PC, if you move 1 meter in the Nether, that's equivalent to 8 meters in the overworld. But given that the overworld is limited to 1024 across, what happens if you travel 1000 meters and then try to come back?
