I'm working on my FiveM Mod Manager so I need to figure out how to read RPF files. GTA5 uses RPF7. After getting through multiple rabbit holes, I deduced there is little to none documentation about RPF7.
Fortunately, I found out Codewalker has RpfFile class (which was very well documented, thanks).
This helped me a lot and it's what I started working off of.
I want to dig through the hard part, so other modders/devs don't have to. My goal is to make the documentation as accessible and helpful as possible!
This project is WIP and most of the stuff is subject to change.
Feel free to create an issue if you find something. Anything helps! 🤗
