I'm not looking for support but for a way to know where things are registered so I can add it manually or if there is a possibility to get a version without removed code
1.7.10 is in my personal opinion the best version as im not happy with the changes Mojang has made to the game since then. I guess you could use 1.8 but there's no cauldron for that version.
starting as more like a personal project but I'm using a lot of spout code so I guess I'm combining forge and spout on 1.7.10. simply because I'm trying to make a mmorpg based on minecraft
