HELP: I have a 16 year old Macbook

i have a 16 year old macbook 2007, yes, the Macbook 3,1

i'm currently trying to restore it — it's not even supported by open core legacy patcher unfortunately, is there any other way to update my operating system on it and make it usable again? if not the latest, atleast a little later version would make it quite usable again ig (it's currently stuck on 10.6.5)
