The only way to obtain Hitmontop in-game is to breed the Hitmonlee or Hitmonchan that you get from Saffron City's Karate Dojo with a Ditto, and then ensure that when the subsequent Tyrogue reaches Level 20, its Attack and Defense stats are equal. However, any Pokémon hatched as a result of breeding with Ditto will have lower stats than average, so I recommend that you just trade for Hitmontop, or Tyrogue.

You can't catch or get a Hitmontop in Emerald unless you cheat using an action replay or trade. In Pokemon FireRed and LeafGreen, choose either a Hitmonlee or Hitmonchan from the Fighting Dojo in Saffron City. Then breed the one you chose with a Ditto at Four Island's Daycare. You will get an egg that contains a Tyrogue. Raise this Tyrogue to Level 20 and make sure it has equal Attack and Defense when it evolves. This will ensure its evolution to Hitmontop. Then trade the Hitmontop to Emerald.
