I have a serious problem.
I'm hacking Pokemon Leaf Green.
I created a new map bank and map. It's 43.0 for me. I redesigned route 1 and put a cave there. I use a walk through walls AR code to get to the cave since you'd need surf to get there and this is the beginning of the game that I'm testing out and editing. I have looked at other cave maps and saw how their warps have been positioned from entrance to exit and I make the entrance from route 1 and exit from the cave to look exactly like other maps and yet there are a bunch of errors.
Route 1 is fine when I enter the cave.
Once I get into the cave, I can't get out normally. Whenever I press down in any part there's the little white arrow pointing down but I can't exit. When I put the walk through walls code back on I can exit but the map gets glitched and I go to Pallet Town rather than the entrance at route 1.
Here are some screen shots of the errors and such.
