I have not really cloned my Minecraft, but kinda. On my laptop I run my Minecraft with command file (.bat) instead of the usual launcher, and on my gaming computer I run it as usual. This is so I can play lan between the two. I learnt how to do it with this video.
This works but I want to change the skin on my "cloned" Minecraft. I have tried to check the launch file (.bat) if I can change something so it gets the skin from a different file or something but I couldn't find it.
If you have any questions please write a comment, and thanks for any help.
