Ask HN: How Would Go About (Legally) Cracking a Game?

I have come across a historically relevant game called Al-Rodwan Operation. It's an FPS game released in ~2010 officially by Hezbollah, about the Lebanese/Israeli war (different than their other series of games, Special Forces).

I was able to get a sealed DVD from the lead developer who wants to remain unnamed. He said he used a custom DRM for the game, and gave me permission to try and crack it, though he was confident I won't be able to. He no longer has access to the source code, and had 2 DVDs left, one is with me.

I have tried everything I know to no avail.

First, I tried using ddrescue, but it got stuck at around 30%. Disc is in great condition, so it was probably the intentional bad sectors by the DRM. I then tried Alchohol 120%, and after 80 hours, I got an mdf/mds files.

But when trying to install the game from the setup, decompressing fails.

I tried binwalk. After multiple hours, I was able to get most(?) of the files, revealing a game using the Cry Engine. But the files are unordered and unnamed, and after trying for hours to reassemble them, I failed.

I have also tried using UniExtract, and was able to get the correct folder structure, but no actual files.

Any suggestions? Anyone willing to help archive and share this game?

Thank you
