Pokémon Emerald Cheats

easier chances
We all know Geodude is common, but if you really want one and know Rock Smash, go north of Mauville, and use Rock Smash on a rock.

Also, if you want a Bagon but don't know Surf or Waterfall yet, exit Meteor Falls through the south. Use Rock Smash on the rock on the right. This one takes longer, so make a secret base above here.

Additional Infomation:
types learn REALLY different moves:

Aggron can learn: Fire Blast and Surf!
Sceptile can learn: Dragon Claw!
Hariyama can learn: Surf and Thunder Punch!

This is a real advantage when taking on Elite Four and Battle Island.
