I thought a modding hook for "Lego City Undercover: The Chase Begins" would be cool since it's the most GTA like game we have on the 3DS and I want to make it but I have 2 questions:
- How hard do you think such a project would be?
- What's some useful documentation I could use? (I've never made romhacks before, I've done some amd64 assembly and modifying hex but not much)
