-- Recording Input while Rewinding Playback frame-by-frame

-- Showcases following functions:
|
||
|
|
-- * joypad.getimmediate()
|
||
|
|
-- * taseditor.getrecordermode()
|
||
|
|
-- * taseditor.getsuperimpose()
|

-- * taseditor.setinput()

|
-- * taseditor.applyinputchanges()

|

|
|
-- Usage:
|
||
|
|
-- Run the script, unpause emulation (or simply Frame Advance once).
|
||
|
|
-- Now you can hold some joypad buttons and press "Rewind Frame" hotkey
|
||
|
|
-- to Record those buttons into PREVIOUS frame.
|
||
|
|
-- Try using this crazy method alongside with Frame Advance Recording.
|
||
|
|
-- This script supports multitracking and superimpose. Doesn't support Patterns.
