Could this work for switch save files? #7

Hi, I followed the tutorial to decompress save files and got this error. I'm wondering if it's because the save file is from the Nintendo Switch version of the game.

Trying to decompress save file "HL-00-14.orig"

The switch save files by default don't have any format like .sav from the PC version. Here's the save file if you want to take a look: https://www.dropbox.com/scl/fi/xue7ml34h6wjgavjjb9h5/HL-00-14?rlkey=t0xdobsx4vtbmt0hiy0cprite&st=wk9botkk&dl=1

File structure is the same on switch and pc. I took a quick look and the file seems fine, however, decompressing that specific block of data fails. I will take a deeper look when I have more time and see if I can fix it. Thank you for your report.

Thank you for looking into it! To give more context, the save file is still in the early game and hasn't reached the point of unlocking Talent Points. I'm not sure if it matters, but considering that the save editor had an issue with it, I thought it's worth mentioning.

I have just tested with a save that has unlocked Talent Points, but still got the same error. The game version is 1.0.4
