The odds of running into a shiny Pokemon in Sapphire are 1 to 8192, there is no discovered way to catch a shiny Pokemon more easily... however if you trade Pokemon with a foreign Pokemon version i.e. American and Japanese, and then make an egg with that Pokemon, the chances of getting a shiny egg quadruple to 1 in 2048.
www.veekun.com has easily retrievable shiny pictures of all Pokemon in all games that have shinies in them.
You can't catch shiny legendary Pokemon without cheats... sorry

Shiny Pokemon are extremely rare. There is a 1 in 8192 chance of a wild Pokemon being shiny. It is based solely on their stats, and there is no easy way to encounter them without cheating. Red Gyarados is the only Pokemon that will always be shiny. If you do have shiny Pokemon, however, it is possible to breed them and have an increased chance of the offspring being shiny. In Crystal, the odd egg has a 50% chance of hatching into a shiny Pokemon.
Meeting a wild shiny Pokemon is around 1:8192 chance. However, on Diamond and Pearl, you can apparently get one more easily by using the Pokeradar in a specific way.
What do you mean how do you make a shiny Pokemon stay shiny if you get a shiny Pokemon it stays shiny ok!
Breading a shiny Pokemon does not guarantee you a shiny Pokemon.
Its really hard to get one you might as well check GTS not waste your life....
Unfortunately there is no way to easily catch a shiny Pokemon without using cheats, however you should know that there is a 1 in 8300 chance that a Pokemon that you come across a shiny Pokemon so you should come across at least one by the time you reach the Pokemon league.
...shiny Pokemon are always shiny... ._.
