Just run the mod menu in a client_script
on a localhost server. You may want to disable the anticheat as well for safety, it’s pretty simple:
- On the client: Go to FiveM Application Data, find and rename
advesive.dll
to anything else (such asdisabled_adhesive.dll
; - On the server: Find
sv_adhesive.dll
and rename it, too, to anything else. - Next, set the server to
sv_lan 1
(as the anticheat being disabled prevents non-LAN connections) and run the menu in a client script. - To enable both after you’re done, rename them back to what they used to be. If they become outdated in the meantime, they should be updated automatically. If that’s not the case, delete the .dll and let it download fresh.
P.S. Of course, just having the mod menu on your machine provided you never launch FiveM’s client is safe - you can review and edit its code freely, but after you’re done with it I highly suggest deleting it off your PC and storing it somewhere online.
