I host my own Minecraft server and have online-mode set to false in serer.properties.
Now, I want others to join but I don’t expect them to buy a legitimate copy of Minecraft. Isn’t that why we use this setting online-mode?
In the ol’ days (1.8 and post), I remember using some copy of Minecraft where I could just change my username on every start of this client, and join my server. Period. Done. I want the same again. Is this possible? In a non-illegal way? What about grey-area? I don’t care about security or impersonation (partly).
Sorry for the late response. I don’t think the mods should be conflicting, just put them both in the mods folder and see if that works. IIRC Valkyrien Skies is required on both the client and the server.
