Thousands of hours of playing Pokemon from Gen I. I've only seen 1 shiny (non-hack). It was I think Generation 4... maybe 5? I honestly don't remember. It might have been SoulSilver. Anyways... the only Shiny that was legit and not Red Gyrados was a Geodude. He sucked but I loved him.
I've tried the Pokeradar but do not have the time to really go through with it. You have to like not have a job to use that thing but some people get dozens of shinies with it...
My first shiny was a Shellos, forgot which game. ^^; Second was an Audino that I just recently remembered! My third was on the second day playing Y. A shiny Gulpin in a horde! My fourth and fifth were 5 minutes apart, Klefki and Pumpkaboo! :D And my sixth is a Girafarig from a friend safari.
They were all encountered in the wild and caught. I have no luck with breeding.
I am having much better luck with this generation. Which means I probably won't get a shiny in any future generations now, lol.

I've caught five shinies in the past 48 hours, in friend safari, three jigglypuffs, and two floettes. I also fished up two shiny claunchers, and gotten a shiny snubbull at random while progressing through the story, caught them all.
But, I've yet to get my dream shiny, a shiny female Ralts/Kirlia/Gardevoir T_T
