you have to get moltres after you beat the cinnabar island gym or the game on one island you got to go to mt.ember. be sure to have the following on you:
1)Save game once you encounter moltres.
2)BUY As many ultraballs as you can carry/afford
3)Have high level pokemon around level 50-60 us atks like moves that paralyze and sleep moves to make it easer to catch.
4)Have an escape rope once you have cought/defeaed moltres for easy exit.
