Early version. It has bugs and the code is messy.
For building instructions, see: https://github.com/snesrev/sm/blob/main/BUILDING.md
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.
