playing emerald for my first time and wondering if there are any tips-and-tricks for an easy playthrough from the beginning to the post-game wallace fight.

for example, in FRLG, you can get a nidoran right away, teach it double kick, and then 3rd stage evolve it by the time you leave mt moon and basically thrash your way easily into the late game. Or in gen 2, how catching a simple geodude will basically make the entire early game a cakewalk...
