[Map] Border block help- inside border blocks showing random tiles

[beastnationred]

I inserted a new map made for the inside of a building that I made, everything was going smoothly until i checked in game and even though in advanced map the border blocks are shown as black the ones in game are showing as random tiles. is there something i'm doing wrong or is there anyway I can fix it?

To fix this, just go to another map, see which block is the border block, and use that block as your border block.
Second, inserting and then making a new map is extremely boring and tiring. An alternative to this is that if you want to add more indoor rooms, you can just increase the mapsize of one of the in-game indoor rooms, to lets say, maybe width=30, height=40. This way, you can just add multiple rooms in one map, adding warps to respected areas, like so:

May I just suggest that you use a FireRed v1.0 ROM? It is much better supported.
