No, I couldn't find an easy fix. The reason seems to be that the game dev decided to encrypt their code and therefore only expects encrypted code, but URM is not encrypted the same way the game expects it to be.
- I've tried to decrypt the original code and change the loader to only expect unencrypted code (and failed)
- I've tried to tell the game to load encrypted as well as unencrypted code (and failed)
- I've tried to encrypt URM the same way the game expects it (and failed)
Unless someone with more proficient skills than me in Python takes a look at it, this game won't work with URM
