I am quite new to retro-reverse-engineering, and I am concerned about my current hobby.
Months ago I started to reverse a 19 year old commercial game, no longer on sale (for ages), and not supported (the company has been taken over a decade ago).
The purpose of my work is not to share the reversed code (as I don't produce code but analyse the existing one) but rather to create a small tool to patch the game.
This patcher would not remove the original CD protection, it would only enable modification of features and behavior of the game. On top of that, I am considering sharing the code of this patcher on a public repository on GitHub.
But as I am approaching the end of my work, I am becoming concerned about the legal implications, because it is clearly illegal to modify an .exe when it is proprietary material. On the other hand I saw a lot of equivalent stuff for old games, and as far I know, their creator were not sued.
My question is: in your opinion, is it risky to complete my patcher, and on top of that, to share its code?
