Make my own local server

Hi there
I’ve been wanting to create my own server to run localy on my own system just to mess around with it for fun and struggled to find any up to date info or files going around the community that I could use to do that.
Anyone happens to know where I could get the required files or has any knowledge on how to do this nowadays.
I know the vsro files have been going around for ages but everything is ever so scarce these days with anything sro related :frowning:
Cheers!
