Mod menu
Do my yew2K settings save when I turn off the Zen?
Yes. Values are written to persistent variables on the Zen and save automatically when you change them.
Yes. Every value you set in the mod menu is written to persistent variables on the Zen, and saving is automatic. There is no save button and nothing to confirm.
After you load a new build on patch day, page through the menu once and check that each value reads what you expect.

This answer documents the yew2K NBA 2K27 Cronus Zen script. Values change with builds — if a number here does not match your menu, check the current value in the mod menu. Questions not covered here go to yew.gg/discord.
