Would it be possible to put a config to enable offline mode?

I dont really know what you want / how it would be possible. If you want LAN sharing Minecraft has it built in. As for offline mode in authentication against the minecraft server: No. I wont allow this mod to work in cracked scenarios

I am closing this as this seems to be out of scope for this mod / ToS of Minecraft. Open again if you think this is wrong with more details.

Ohh okay thank you anyways
