This patch creates reflections at the current FX Surface level, creating a mirror effect using duplicate sprites and HDMA for bg layers
Shoutout to Dman for inspiration, and PJBoy for the disassembly.
Use Asar to compile, xkas won't work!
Also, due to a very stupid Asar quirk, you need to rename the .smc file extension to .sfc before applying, otherwise it'll assume the file is headered.
