Regular client with autonexus

I was wondering if there was a client with just autonexus out there that didn't affect visuals? I remember there being a client builder that I downloaded on here around 4 years ago which allowed me to build a client specifically with the modifications I desired. I could also update the client with a click of a button. Oryxrape was the name of the application if I'm not mistaken. My memory is blurry but I think there might have been the name Nilly's mentioned somewhere, maybe inspired by said person.

I may have the files saved somewhere on my mom's old computer, but who knows if it still works after all these years.

The most simplest way to do this without spending too much time is K-Relay(add proxy into your server list) and use the auto-nexus plugin.
