You can not catch it in leafgreen,but in firered you can.
you need to start out with bulbasaur at the start of the game, beat the game, get the rainbow pass, encounter then track entei then try to catch it.
in leafgreen and in firered you can capture entei if you choose bulbasaur as your starter. and after you have won the league, entei is wild everywere
Neither one of those pokemon are obtainable in Sapphire you must trade one from Firered, Leafgreen, or Pokemon Colosseum.
Entei is only obtainable if you Migrate it from FireRed Or LeafGreen, or if you migrate it from another GBA game that has traded with Colosseum for Entei. So, you can't catch Entei in-game on platinum. You can only trade for it.
Nowhere no hoenn Pokemon can be captured in leafgreen.
