Supercade record game?

I have read somewhere that supercade has a record matches feature. How can I enable this? Which directory has the saved replays? When the game ends, supercade does not ask for save replay.2DF was cool cause, you could watch replays from any game and learn how to improve your game vs better players. I hope supercade will get an update with this feature back. I noticed it runs smoother than 2df and crushes less often. Very promising wip from damdai, hope for more updates btw.
