how do i get the team magma out of the way in slateport city? they`re blocking the way to the museum and mauville city. help!
go to stern's shipyard. go straight into the room and talk to the man in front. he will tell u to give the devon goods to captain stern. after talking to him, go back out and into the museum's first floor, where u will find stern. talk to him. (after talking to the man in stern's shipyard, team magma will not block the museum anymore.)
