First of all, I hope this is the right section for my request. I know there is a seperate gamesave subforum, but my request is (hopefully) "just" about compression and not checksums etc.

I'm trying to decompress the save file of Silent Hill 3 on the Silent Hill HD Collection (.SH3). Silent Hill 2 on the same Collection is not compressed or encrypted at all.
I've tryed offzip with all possible window values, no avail. Then I tried comtype_scan2 and looked through the dumps for 2 hours, but I guess I'm to inexperienced to distinguish what result is plausible.

So please, could anybody take a quick look at those save files?
I'm attaching 2 saves. The first one has 31 handgun bullets (00 1F), the second one 28 (00 1C). Both have 10 shots loaded in the handgun, 4 beef jerkys, 5 health drinks and 1 ampoulle.

Maybe this could be the length of the compressed block (just a guess in the wild):

There's also some uncompressed text that is shown at the loading/saving screen at the end of the file:

I've also included a Silent Hill 2 save file in the attachment (.SH2)
The inventory begins at offset 563 (hex): 11 health drinks (00 0B), 5 Medikits (00 05), 00 00, 10 Shots in Pistol (00 0A), 180 handgun bullets (00 B4).

A big thanks for anyone who tries to help me out

Just let me know if you need any more samples or other files (the .xex for example).

Come one guys, please

I'm thankful for any piece of advice.
