Hi, friends. As you know, PC version is currently broken after the major update including visuals, controls, and mods. I wouldn't expect devs would make the same mistake of breaking mods again. That's why I didn't back up the v109 installer, and I'm afraid authors won't bother making them compatible with the latest version anymore. Thus, v109 is the final version if you want to play maps & mods. I asked the installer from GOG support, but they couldn't provide it. I know it is possible to roll back on GOG galaxy, but I prefer to keep my backups as installers. So, I desperately pirated the game that I paid for thanks to GOG & SNEG. Yeah, what a joke. However, I need to make sure that it's virus-free. If someone who downloaded v109 installer files (*.exe and *.bin) from gog.com can share the MD5 checksum of these files separately, I will appreciate it.

P.S. You can do MD5 checksum in Windows 10 using PowerShell by using the command syntax: Get-FileHash <write here full path of the file> -Algorithm MD5

You're so lucky I just saw this before deleting my old installer. Thanks for alerting me to the value of v109 btw.
Anyway since I'm too lazy to use MD5 when I can pull SHA-1 & SHA-256 from right clicking with 7z, I'll be providing those hashes instead.

GOG really needs to start providing these by default tbh. Ideally you could request a custom DAT of your whole library at a whim.
