;WRITTEN: by XaserLE
;THANKS TO: -MathOnNapkins' Zelda Doc's
; -wiiqwertyuiop for his Zelda Disassembly
;===========================================================
; Reveal Secrets with Book of Mudora
; Makes BG2 Disappear when pressing X+R
; Based on the Parallel Worlds feature
;
; Bank 0x3C used for whole code
; Layer Flags: xxxsabcd (i count BG from 1 to 4 - MathOnNapkins RAM-Map counts from 0 to 3)
; s - Sprite layer enabled
; a - BG4 enabled
; b - BG3 enabled
; c - BG2 enabled
; d - (BG1 disabled) --> only works properly if the room uses the feature "BG2 on Top"
