; ==============================================================================
; ZScream Custom Overworld ASM
; Written by Jared_Brian_
; With help and testing from Jeimuzu, Letterbomb, Scawful, and Zarby89
; ==============================================================================
; The purpose of this ASM is to give users the ability to customize many aspects
; of the ALTTP overworld that were previously hardcoded.
; Features include:
; The ability to add a mosaic on any transition.
; The ability to change the main palette for each area.
; The ability to give each area a custom background transparent color.
; The ability to give each area its own tile GFX set.
; The ability to give each area its own animated tile set.
; The ability to add or remove a subscreen overlay on each area.
; (rain, fog, sky, lava, pyramid, etc.)
; The ability to disable the rain in the beginning phase.
; Removed hardcoded exits playing music instead of using the area's set music.
;
; To achieve this, large portions of the game's vanilla code had to be edited or
; even re-written entirely to instead read from tables in expanded space. These
; tables are written to and generated by ZScream. Tables based on the vanilla
; configuration can be used by changing the debug variable !UseVanillaPool
; down below to a 1, thus removing the need for ZScream although this is not
; reccomended for your average user.
; Some of the new features require a bit more computation time (to decompress
; GFX for example) causing load times to be slightly longer (1-2 frames more at
; most). Because of this, I have made it so certain features can be disabled to
; instead use the original vanilla code if speed is prefered. See the
; EnableTable below for more details.
;
; There are certain things that are still hardcoded here as a result but can be
; changed if you know a bit of ASM, such as:
; The rain that is originally present in the Misery Mire area.
; The Lost Woods changing to the tree canopy overlay after obtaining the
; master sword.
; The fog overlay being disabled after obtaining the master sword in the
; master sword area.
; The bridge overlay present in the under the bridge area.
; The BG color present in the under the bridge area.
; The pyramid overlay only scrolling properly on area $5B.
