.dm3 demo help!

[chodda]

I have a demo recorded, the .dm3 file seems to have been corrupted??

Halfway through the demo, the server changes map, and then the demo just crashes, the whole game actually crashes to desktop.

Help?? Is there a way to repair this .dm3 demo file?

I'm not sure. In all honesty, considering it's a .dm3 file, it's been recorded with a very old version of Quake 3. That means there might have been a bug in Quake 3 where a demo causes Quake 3 to crash when the map is changed in the demo.

You could try recording a new demo where you then change the map and try to play back that one. If the same thing happends, it's Q3, not the demo.

Your idea is just to test the game to see if it will happen again, it doesn't exactly help me fix this demo

I have some very good footage that I am trying to recover!

If it helps anyone, the game is MOHAA.

Demo files are .dm3

and this is what scrolls in console when it crashes

No, but it will help to pinpoint the exact location of the problem. I still would suggest you try it. It could be a bug with Medal of Honor itself in which case it's kind of futile trying to fix your demo. If freshly recorded demos do work, then further investigation is an option.

If it helps anyone, the game is MOHAA.

This is very important information actually. You're talking about a completely different game...

Demos always work. Very rare do I have problems. This is one of those rare problems :/

I still have hope because the file size is correct. It's a large file, this particular file size is correct for the total length of time I was playing.

But, it crashes only 5 minutes into the demo. Based on file size, I assume it was still recording, I just can't seem to get past this map switch glitch.

Someone suggested I edit the file, somehow cut it in half. So the demo starts at a later part. Skipping the glitch.

How do I cut .dm3 files in half? LOL! Any ideas?

MOHAA is built on Quake III engine. Hence the same file types.

I have no idea if and how it would be possible to edit demos. Just to be clear about one thing: demo files are .dm3 files, not .pk3

[chodda]

Whoops, yeah I knew that ^.^ Just a typo. I've just been going crazy trying to think of ways to get this to work!

Edit demos? For all practical purposes: no. Demos are essentially binary dumps of network traffic and player input.

[VolumetricSteve]

the footage you want is before the demo causes MOHAA to crash, right?

I'd just do what the rest of the world does now and use some program like Fraps to make a video(mp4, avi, what have you) of what you recorded, then, just distribute a file that everyone can watch, not just MOHAA players.

[chodda]

No. The demo crashes before I can get to the part I want.

Ohhhh that sucks....you might be out of luck then. Short of Hex-editing the file....I can't think of what else you could do, and Hex editing is about as likely to work as eating a box of live scorpions and living to tell about it. And roughly as fun.

Well, to be honest, while I haven't seen such a tool for Quake 3, you can edit Quake II demos with a tool called KeyGrip2. You could change camera positions and add sound effects and texts and such.
