Majora's Mask - SoS Message Script

-- sos_messages.lua
--
-- For use with Majora's Mask (U)
-- Open up the Song of Soaring menu before activating the script
-- The resulting messages will be stored in a file called 'SoS_Messages.txt'

-- Author: @Faschz
-- Created: November 4th, 2018

-- Address for the message table and corresponding length of message in the table
MESSAGES = 0x1D0714
LENGTH = 0x1D07C4

file = io.open('SoS_Messages.txt', 'w')

-- Normally there are 11 messages in game...
-- However, with clever use of 'Index Warp' new strings can be written
-- to the text box that appears. This also overwrites unintended ranges of
-- memory.
