[PC] Zone4 (.sod, .img, .mod)

Game links: 

https://drive.usercontent.google.com/download?id=10BaAnqeX1itu_kWtQJPIC-tgQ3ZJDB_P&export=download (full client of a private server that used to existed)

https://www.zone4extreme.com/download (Zone4 Extreme - The only remaining official server)

All file formats (sod for audios, img for UI images, mod for archiving models, textures, etc...) seems to use a charset replacement method (see here: https://hcs64.com/mboard/forum.php?showthread=52948), but no progress beyond that, I don't know if the method has changed over the years so i'll put the link of 2 game versions that's few years apart in case it does.

Ok, so for the private server one, i found a bms script that's able to decrypt the .sod files, as well as the .dat files which store various scripts (didn't try them on the Zone4 Extreme ones yet):

But it seems like the .mod and .img use a different kind of charset replacement, or even a different kind of encryption entirely. Below are some samples for the .mod and .img files in case anyone wants to take a crack at it without downloading/installing the full thing.
