| Description: | In short: This patch frees 3 bytes of RAM by rewriting parts of the code that load Switch Palace blocks and trigger them. In long: SMW by default uses RAM $1F27-$1F2A to determine which of the four Switch Palaces are triggered. SMW sets each of these to $01 when the associated switch is pressed. This patch rewrites the scenarios that these addresses are read from or written to, and instead sets the lowest 4 bits of solely $1F27. This leaves the 4 highest bits of $1F27 as well as the full 3 bytes of $1F28-$1F2A free. |

Works properly. Friendly reminder to whoever is using this to change whatever resources you're using that affect the switch palace flags.
Added sa-1 and lorom tags.
;; In vanilla SMW, the game uses the range of $1F27-$1F2A to dictate which of the 4 Switch Palaces have been triggered. ;; It only sets these RAM addresses to x01 and is never written to again. ;; In this patch, it will read and write to the lowest 4 bytes of $1F27 (by default). This essentially leaves $1F28-$1F2A free, ;; though it's still read/written to during the load/save functions.You mean bits.
Also, is the order of the switch palaces the same? Like is it formatted as %----RBYG on $1F27?
For ASM hackers, 3 extra bytes of RAM that are saved/loaded to SRAM might be useful.
