Early version. It has bugs and the code is messy.
Put sm.smc (sha1 hash da957f0d63d14cb441d215462904c4fa8519c613) in the root folder. When running, it will run both versions and compare frame by frame. If it detects a mismatch, it saves a snapshot in saves/ and displays a counter on screen counting down from 300.
