According to the README credits, LongerWarrior provided a "truly massive collection of games to test against".
Do you still have these games? If you do, can you please provide a list of all the games that are currently supported?
I think it would be very helpful to have such a list in the README.md for future references.
Personally, I would like to know which are the oldest Unreal Engine versions that UE4SS supports out of the box so that I can test the compatibility of certain changes I have worked on.
