I just like to see, whether the leak protection is as the dev says and it'd be a fun little challenge to find the different images.
Edit:
Since it sounded like fun and I wanted to see how difficult it really is (didn't do any programming in a while), I made a small program that can go through two folders (e.g. two /game folders of two copies of MEL) and list all differences.
I don't have access to different downloads from the same batch (e.g. two copies from different Silver subscribers), but in this thread you can download both version 10.01 (which got leaked?) and 10.02 (free version from Patreon). At least the images in both versions are 100% identical. Most/all of the rpyc files are different. Though, that is to be expected since I compared two different versions.
The comparison of those two versions in itself doesn't say much. I have no idea, how renpy works and how the rpyc files get compiled.
I'd need two different copies of the game from the same tier to get any information, whether / how copies are individualized.
