New to git made the acc just for this
Is it theoretically possible for this to work for new Minecraft versions and if so how do i use this

I was going to try figuring out how to trick the server into thinking i was another player so i could get the ,json files which would be hard but i found this everyone says the existence of this is impossible i was shocked that no one mentioned this ever bro you should totally update this

like it isnt made for new versions but could the code technically work with new versions

i don't know if the dat file format has changed much so it might still work
