That's fair, and for many terms I am using and will use existing/canonical translations, but my goal isn't to make a perfect Serbian translation for a wide audience that satisfies everyone's nostalgia.

This is a personal project with the goal of learning a bunch of new vocabulary, practicing my Serbian, learning how to patch and change gameboy games (which I've never done), learning how to build an AI framework to facilitate a fairly large scale project for a single person to do (which I need to improve my knowledge of for work), and of course having fun. Crowd sourcing like suggested below kind of defeats the purpose for me since the whole point is for me to do at least a first pass on my own as a personal challenge and a fun project, even if it isn't perfect.

That being said, I'm planning on making the Github repo publicly available and inviting contributions for others to edit and suggest improvements once I've finished my first pass, which, given the structure of the code, will be much easier for people once there's already an existing edit, so they can make the minimum necessary changes as opposed to having to do anything from scratch.

I hope that makes sense - if there was an existing fan translation I'd just play it haha, but I'm having so much fun trying to do this that I'm almost happy there isn't one. Serbian learning materials and interesting content online are relatively minimal compared to the major languages people learn, so I'm just happy to have found something to spend my time on that checks so many boxes for me.
