-- NES Braidulator VERSION 1

-- A Lua script that allows 'Braid' style time reversal for Nes games being run in FCEUX
--'Braid' is copyright Jonathan Blow, who is not affiliated with this script, but you should all buy his game because it's ace.
--This is my first ever time scripting in Lua, so if you can improve on this idea/code please by all means do and redistribute it, just please be nice and include original credits along with your own :)
---2016 Note: Super C. (Konami) Work Very Well! (Duckmite Note)
---Charge Power And Press Select To Work


--Change these settings to adjust options


--Which key you would like to function as the "rewind key"

--Do not set to 0!
