Er.. I thought this would be pretty straight forward but whenever I define a new offset for the map it glitches my title screen for some reason.
I need this.
I'll take the first offset, the tilemap of the normal region.
Now, make the pointer of it.
[3F][F4] -> [F4][3F]+ -> F4003F08.
Search for it in your rom, and change the pointer, take your offset (mine was $810000 -> 00008108) and correct the old.
I really don't understand what this part is trying to say at all.
