Enable offline mode in SKCraft launcher | open-source

[xovermindx]

Hello. I have got a question. Im using SKCraft launcher (its open source project at ******, easy to find in google) to create my own modded client. So the problem is that it only supports premium accounts, i cant even test my build without premium. And so I think its possible to change some code in auth dialogs that launcher will create profile in offline mode by default. I know a bit java, but maybe not good enough to solve those things alone. I hope that someone could help me a bit.


p.s.
Not really going to use it in commerce, but i think that almost 30$ is too much even for personal use and testing mods.

up:
q. why i cant use another cracked-client?
a. because i want to test auto-update with my site and that option is natively supported in this launcher. well, if there are any other easy methods to create your own launcher - let me know. ty
