.zds save problem

[DiGet]

Is there any way to open a zds file in notepad (or other similar programs)? I've been playing GZDoom with some mods and saved a game. Later (after a month or so) I tried to continue playing from that save, but I forgot the versions of mods I used and exact order of how they were launched. So is there any way to open a ZDS save file to see which wad/pk3 files I used?

P.S. Please don't suggest to just restart a game with different ones, I was almost at the end of the game.

There has been a recent format change, approximately 3 weeks ago.

The old format is stored in a PNG, you may have luck finding the needed info when loading it into a hex editor.
The new format is stored as zipped JSON, you can open those with any archiving tool and look at the file info.json.

Thanks for replying)

I was running old version of GZDooM, even loading it into a hex editor didn't help.
I should get a new version)
