Your Save in KH 1.5 & 2.5 on PC is a PNG
- Thread starter Mankoto
- Start date
Steganography wouldn't show up in a hex editor, so presumably they're storing save data in an ancillary PNG chunk.
I doubt it. It's probably just embedding the save data information inside PNG metadata chunks.
iTxt
tExt
zTxt could all be used to store arbitrary data
They might just be using Adobe XMP to embed whatever metadata they want here, or they might have just developed their own tags:
And this is a note about ancillary chunks. So you can put absolutely anything there, including garbage data, and it won't corrupt the PNG file whatsoever:

It's weird in this case because why...?, but it's not really a new thing. I can remember Spore did something like this, and in that case it made sense, because it would be an image of the creature that you were saving, so you could send the PNG to other people and they could see it and potentially load it in their game if they liked it.
Because having your save data in an image that says "Save data" and the logo of the game seems much cooler than a txt or similar lol
the image holds all the hex variables that a normal save file uses.
It's just a PNG except with extra data included that is your save file.
Note that the save file isn't incorporated into the image, it's just that the PNG file has a portion that's the image and another portion that is your save data.
Save data is typically stored in .txt files since those would produce the smallest file size. Saving it in the metadata of a .png file is possible but it just seems really unnecessary.
I don't get all of this mumbo jumbo, I just used an entire Memory Card for the PSX version of Diablo and that was the end of it.
(Thanks for the insight! Seeing that someone just uploaded a save game through that PNG is just bonkers, that was an unexpected twist, lol.)
Nothing new, doesn't make sense unless the picture is something that's related to the actual save file, like the character you're using and their equipment....
...or lack of equipment.
...or lack of equipment.
I doubt that was the intention, but making it an image makes it more intuitive to share on social platforms or forums compared to linking a txt file. I seem to remember some game where users could create something and share it via a generated png that showed the creation as well as includes the data for it.
Edit: Did I accidentally remember the mechanism of some adult game here? lol
Brb gonna sell my 100% KHBBS save on the NFT market for 3000 bit coin.

Reddit could've delete non-standart chunks from file.
But we need someone to check to know for sure.
Oh yeah looking at that video, if it's the same file, then that's exactly what happened. In the video you can see the tExt chunk right at the start.
The file was 6.74 MB in the video. It's around 70 KB now.

Well, that certainly limits it's sharing potential. I imagine most image hosters do something similar to prevent storage abuse.
The idea is neat, though.
That is exactly how characters in a certain hentai game are shared lol. Outed yourself there :P
To emulate what the save data actually looks like on console
I actually really appreciate the extra mile they went here
