I've beaten the Kanto E4 yes, In the process of taking on the Jotho as we speak. why?
Because PRO is different from handheld games. Here the Bell tower is a part of the Celebi quest and you need the whole
Johto pokedex complete, to be the Johto champion and also a certain amount of in game time to access the Bell Tower.
Alrighty. So basically, there's no way in hell im entering that tower. Oh well, guess i'll just have to buy a Shuppet...
