Diego my script is, again not working...
I've already sent the patch to Hiche, an experienced scripter and he said it should work... Should I send you th patch too?
Well, it's most likely a problem with the map than with your warp. Just go into A-Map and navigate to your room (4.1). Then click on FIle>Map>Insert map and in the top row, select a map bank of 4 and a map of 1, then click insert. Your ROM should refresh. Now test it out in game!
