For added context, I'm using Leon and UltimaSoul's fire red rom base, and I used PGE and Advanced Sprite Editor to change Charmander's sprite and name, and I made some other small changes to Charmander just to mess around (I'm just trying to learn). But when I start up a new game to try and see if the changes worked, I can't progress because there seem to be a bunch of invisible walls in the room that prevent me from walking far or leaving. Has anyone else encountered this? What did I do wrong?
I don't know what caused this error.
But there is a fix, open your ROM in advancemap and open the bedroom map,
then open the "movement permissions" tab,
after that, fix the permissions (red 1= impassable, purple c= passable)
