(adsbygoogle = window.adsbygoogle || []).push({}); Looking to learn how to update old mod menus or menu bases from 1.18 or lower to 1.19. Would like to know how its done.

if you have the source just update the offsets most of them increased by + 0x80 for 1.19

Can I just use a 1.19 offsets and put them in a 1.18 source?

yes its same thing
