To record a demo in debug mode, load the level, and then (although this may not be necessary), press 2 and W to stop any demo recording or playback. Then, press 1 to start recording your demo. Press P to play the level, (make sure Caps-lock is on, but you probably already know that), until you beat it or until you die. Once you've done that, press the ~ key to get back to the debug mode. You should notice that there is some data in the bottom textbox. This is your demo data. Press 2 to stop recording the demo, and then you can either press 4 to save the demo to your clipboard (so that it becomes the next thing you paste), or you can just copy it directly from the box. Once you've done all this (it sounds like more than it actually is), paste it in the demo data box in a reply if you want to show a demo.
To play a demo in debug mode, first paste the map data in the top box (make sure to click outside the box before pressing L, then, paste the demo data in the bottom box, click outside the box, and press 3 to load the demo data. Once you've done this, press Q (which will reset all objects) to begin demo playback, then press P (capslock on) and watch.
Alternatively, you can simply put the map in your userlevels.txt (follow the instructions, and copy the data from NUMA, not the raw data). Once you've done that, go to userlevels, and find your map. You will need to beat the level in order to get a demo, so when you do, quit the level, and on the left inside the replay box, search through the long code until you find a part that looks something like this: #1234:187424|125828|. Copy that down until just before the # at the very end of the code (the reason for this being that NUMA will not allow you to post a demo with that final #... for whatever reason...) and paste it in the demo data box in a reply if you want to submit a demo here.
To play a demo in userlevels, paste the full map data (from here) in the replay box, then paste the demo data at the very end of the map data, add a # at the very end of the entire code, and click watch replay
