--FCEUX Subtitler Express v2, by FatRatKnight
-- I find the built-in subtitles for FCEUX's .fm2 is somewhat inconvenient.
-- This script should make the process smoother.
-- Run the script. Type whatever you like. Letters and such will appear at the
-- top of the game display. The script can output a line of text that FCEUX
-- can understand and translates into the appropriate subtitle. It can ouput to
-- a file or to the display box
-- Whatever the script outputs, you can copy that and paste it into the .fm2
-- file in question, right before where all the actual frames begin. I suggest
-- WordPad to open the .fm2 file.
-- If you're really that lazy, run a movie, subtitle it, then hit pageup twice.
-- The movie will be stopped, but this script will replace the old subtitles
-- with the new ones. It will actually create a new file appended with _S in
-- case the script royally screws up somehow.
-- Let a frame pass, and the text becomes translucent. This is to signify that
-- the text will remain visible as an actual subtitle, but you can put in a new
-- subtitle here without destroying the old one. It will just override the old
-- subtitle when it's time for the new one to show up.
-- Still, when it comes to translucent text, it's pretty dumb around loading
-- states. Don't try to worry too much about it.
-- Beware of hotkeys you set in FCEUX, or even the defaults like I, P, shift+R,
-- shift+L, comma, and period. These can and will interfere with this script
-- if you don't disable them.
-- Please don't try to type while emulation is unpaused. This script is not
-- smart enough to know how to handle unpaused typing.
-- Don't let the warnings scare you. I hope the script makes subtitling easy.
