Support for Riders Republic

[codeaid]

Apologies for posting Assassin's Creed unrelated question here but I couldn't find a better place to ask.

Similarly To Assassin's Creed Ubisoft's Riders Republic seems to have packed everything into .forge files. I was looking for ways to extract some images from them and found this tool. I know it's not made for RR but seeing how it's potentially the same (or maybe a slightly different) format I was hoping it would. Unfortunately it doesn't.

When I launch the application and pick game's directory I am presented with this:

However when I attempt to decompress the file the application simply closes and there's nothing in the logs.

Is there a way to make it support this file format or has this project been abandoned? Alternatively, maybe there are other tools out there that would do the job?

Thanks in advance!
