Hints and Tips
Gamecorner
In the rocket game corner, there are machines that have better odds of winning than the others, go to each machine and play it 5 times, if you win 3 or more, you've got a lucky machine!
There are coins all over the game corner, just walk around and press (A) and you will find coins.
Fighting
I recommend the following pokemon fighting squad:
Mew*
Machamp
Dragonite
Mewtwo
Articuno
Venomoth**
*If you don't have a Mew, than use a Gengar or and Alakazam.
**Venomoth is good because of his abilities to put pokemon to sleep, butterfree is just as good.
Develop anti anti-mew squad or an anti-mewtwo squad, put in Exeggutor and Slowbro because psychic attacks can't hurt them.
To wake up your pokemon if they're sleeping, use a pokeflute.
Watch out! Gengar can learn psychic!
Dig is one of the most effective attacks against ghosts.
Other Strategies
If you are fighting a rare bird, save before you fight him, that way if you lose or kill him, you can reload and try again.
If you find a good TM, don't use it right away, same with rare candies. Save them for the Missingno. trick that way you can have multiple of each.
Find a crappy pokemon who can learn many HMs, teach all the HMs you can to it and use that pokemon as your tool pokemon, and the rest for fighting.
Dragonite is one of the strongest pokemon in the game, get your dratini into a dragonair and the dragonite as soon as possible. Dragonite is strong against everything except ice-type pokemon.
