Hey auramxrky,
ForgeWurst (not WurstForge) is an older version of the Wurst Client that works with Forge for Minecraft 1.10.2 and 1.12.2.
ForgeWurst never made it out of beta and is missing a lot of features because of that, but it's a historically important version because several modern Wurst features (e.g. ClickGUI, Tunneller, MobSpawnESP) were first developed in ForgeWurst. It also has a ViveCraft VR mode which is a lot of fun.
You can find downloads and more information about ForgeWurst here: https://forge.wurstclient.net/
The installation guide is here: https://forge.wurstclient.net/tutorials/how-to-install/
(It works like any other Forge mod from that era.)
I can't help you with pirate launchers like TLauncher. You'll have to figure that out on your own.
