I was thinking about speedrunning glitches 1.16.1, how do I duplicate the items.

Have you tried watching how other runners do it? Or look it up on youtube?

yeah, I just wanted to know if there was anything specific I needed to know. Isn't it like: you save and quit then put items in a crafting table then close the game and reopen?

Yeah you close the game using task-manager, I think that's pretty much it

ok, thanks

or using alt+f4 i think

Idk
