Rate of Time Manipulation Script

--"time.lua"
--For use in MM (U) on BizHawk 1.9.1
--Z to go back in time
--X to go forward in time
--C to toggle between normal rate of time and inverted rate of time
--Keep in mind that time is separate from day, trying to go back a day will instead take you forward one.

--Addresses:
--0x1EF684 determines if ISoT has been played
--0x1EF686 is Rate of Time
