So I remember back in 2022 i played Minecraft free using modrinth, adoptium and minecraft launcher with one of my friend, we did install the e4mc mod too and those were some splendid days now that I look back at it, so I've been trying to make it work but unfortunately I can't remember how it worked, is there any way on how I can again play with my friend? I can't afford to buy Minecraft at the moment but if anyone is willing to guide me through i would really appreciate
