Allows for the full horizontal screen as an overworld.
Hijacks: too many to name, look in the ASM file.
Doesn't use Free RAM.
Note that custom OW sprites need to be modified to include using the X position high bit in $0420 and up in their graphics routine.
Thanks to Vitor Vilela and Alcaro for helping me make this.
For newer people running into this patch you need to edit the OW border or you want see the effect.
If you don't know how to edit the L3 border just do the following.
Load OW → File → Layer 3 Submap → Load Layer 3 of submap
Pick the map you want and edit out the sides one by one just don't forget to save.
Take Border.bin, rename it into ExGFXyy.bin (yy being a not used number between 80 and FFF including), insert it, go to the overworld editor and change the layer 3 tilemap () into the ExGFX file. (stolen from MarioFanGamer)
You want to use the lower settings make sure "Enable bypass of standard layer 3 tileap" is checked and then use "GFX Tilemap file LT3"
the bin file provided with the patch isn't a graphics file it's the tilemap for the border.
There seems to be a problem with luigis ow sprite. It's left side disappears, atleast in sa-1. (Didn't test without sa-1)
Fixed it by removing this 2 lines, but i don't know if it causes any other bugs:
Looks pretty nice actually! I haven't tried this patch out yet, but does this patch also makes the overworld screen a bit centered too?
Like, as shown in the picture, the overworld map is a bit more to the bottom.
I know it sounds like a silly question, but I want to make mine so that the Mario sprite (in the upperleft corner) is standing somewhere else, same goes for the name of the level.
