RbxDumperV2

An offset and FFlag dumper for Roblox.

This project was originally created for researching and reverse engineering Roblox internals and gaining more experience in using tools such as IDA. After sharing some of my research and findings, I started getting requests for offsets, which eventually led to the creation of RbxDumperV2.

After working on the project for a while, I have decided to make the source code public. At this point, I don't have much motivation or interest in actively developing the project anymore, mainly due to the community surrounding it.

I will continue uploading offsets to offsets.imtheo.lol whenever Roblox and will fix things when they break, but don't expect frequent updates, new offsets, or major features from me.

If you'd like to add something or improve the project, feel free to open a pull request. Just make sure to read the contributing guidelines first. ;)
