Right now I am currently forking the entire ROBLOX core, from server to CoreGui. Of course there’s going to be features that are locked, such as SelectedCoreGui (Just change to SelectedGui) and game:GetFastFlag() (Just use my FastFlag API and write CoreMfdFFlagService:GetFastFlag()). But I have no Idea on how to do the FastString method. It’s a pitty that roblox won’t let us have FastFlags and FastValues in our own games. What I have tried so far is to Edit my API and to no avail.
I am stupid as hell, just remembered about datastores ._.
