XCOM:EU support #2

Closed golinski closed 5 years ago

golinski commented 8 years ago

I am trying to add support for the vanilla XCOM:EU files (version in header: 15). Are there any resources I could find useful in understanding the binary format? Or maybe the only solution is reverse engineering? Your code is very enlightening, but hopefully you can point me to other resources.

tracktwo commented 8 years ago

I haven't found any documentation about the format, unfortunately. The contents of this project are what I managed to learn from this project by Kelnor277: https://github.com/Kelnor277/Xcom2012SoldierViewer plus what I've reverse engineered myself. If you're looking at geoscape saves I can't imagine the format has changed that much between EU and EW, but I could be wrong. Tactical saves are a whole different beast and I've not figured out how to even parse them, nevermind interpret the data correctly.

I am also interested in this. Tried to use xcom2json on a tactical savegame from Linux XCOM: UE and this is what I got:

[2:05] [3666] [patola@ovo build]% ./xcom2json save36 
Error: Data does not appear to be an xcom save: expected file version 16 but got 15
Error (0x0000002e): Malformed actor table entry: missing 0 instance

Also tried to decompress it to see if it would work, but it did not - it seems this software is prepared to automatically decompress the savegames, right?

tracktwo commented 7 years ago

It does handle the decompression, yes. But unless golinski has made any progress in reverse engineering the EU file format I suppose it isn't as simple as just checking for the slightly older version number, unfortunately.

golinski commented 7 years ago

At my repo you can find a branch that has support for EU. Changes are not big, but scattered throughout the code, and I have not tried to integrate into the codebase and make a pull request.

Great stuff! I'll add a link to your repo to the main page. If you ever get around to submitting it as a PR I'll definitely include it!

Anders1232 commented 5 years ago

I made the PR #14 with the merge. Hope works nicely.

Thanks!
