Yup, that's it. I posted it a long time ago when I thought I was done with Supcom. I posted links to it back on the gpgnet forum but no one ever responded to it so I figured it wasn't being used anymore. I used it as a code sample for an interview years ago so I refactored it and commented the crap out of it so I think it's reasonably in a good state to be shared. Looking back on it though it's still pretty terrible code. I can add folks to the project admin if someone is interested in helping work on it. I have a reasonable amount of suggestions in my head for how to improve it as well as being available for any questions.

Hath, is FAChart's code publicly available anywhere?

Blarg, I got distracted by school. I still mean to update FAChart and/or roll it into FAF. I am easily distracted but I should have some free time during the winter break (aka December). Folks who are interested in an update could help me by pestering me to get it done. I mean send mean helpful reminders by pm.

Originally, I found an outline of the format provided by one of the game devs. I then looked at a lot of replays in hex and then got some help grepping through the FA.exe to make sense of some of the numbers. I then made judgment calls on what something did and didn't do.

I'll update FAChart to work with the new format. I don't think it should take too long. As for the python version, I do know python but I'm pretty sure it would take me some time to do that. I am interested in doing it though.

Are there specifications anywhere on how to read the FA replay file format?

Or, in other words: how did the original FA-Chart do it?

I know this is asking a lot more, but If you know python, you can eventually complete the replayparser.py file in the repository (now it only parse the header), and we can plots all the datas with mathlab easily. (already in the lobby, like right-click on a player - view statistic).

That way, FA-Chart would be implemented directly in the lobby !

You can already use FAChart. Simply start the replay you want to run it on, and then look in C:\ProgramData\FAForever\Cache\temp.scfareplay. Run FAChart on that file.

I highly doubt it.

ok, half of that was old SCFA replays. just so you know average size is 230kb for me. now you know.
i will now stop wasting your time

Ze_pilot, who should I talk to about the new replay format and how I might make FAChart compatible?

You can find the encoding protocol here :
https://bitbucket.org/thepilot/forged-a ... yserver.py
(after def writeReplayFile(self) )

Basically, to decode it, you need to
- strip the first line (a json string).
- Strip the following '\n' character.
- Base64 decode the rest of the file.
- unzip it the result (a standard gzip library is used).

I highly doubt it.

On the server, the total amount of replays that was ever played on FAF since the .fafreplay format exist is 7.0G.
There are 88.513 replays in the directory.
That's an average of 0,08 Mb per replay.

300 mb of replays mean that you would have played about 3.750 games.

But the database only recorded you on 837 games.

Maybe you only played 837 12 vs 12 1 hour games only, or you are mistaken.

Your replay folder should be about 66 Mb. Zipping it would reduce it to about 60 Mb.
