I got SAO UI from Curse and tried to see if it could work in 1.12.2. However, I figured that it would just say that it was made for 1.9.4 and got confused as to why it didn't do anything.
I am trying to use a mod in Minecraft 1.12.2, but, when I start up Minecraft, the mod won't show up in the Mods menu and it won't do anything. The only shown mods are the 5 default ones for running Forge. Any help?
