In Black and White, most shinies just appear randomly. Go walk in grass and see lots of Pokemon, and eventually some of them will be shiny!
And yes, you can use a Japanese Ditto to get shinies. If you put the Pokemon you want a shiny of in daycare with a Japanese Ditto, your chances of getting a shiny are much, much better. You still have to hatch lots of eggs, but you'll get a shiny faster.
Ok! im just asking about that.... But you known how shinnies appear in BW?? and it's true the 'shinny making' with an ordinary pokemon and a Japanese Ditto?
We'd be glad to let you join! It's okay if you can only play on weekends - it's better than not playing at all! ;)
Sorry, but you can't use Pokesav. You can only play the games regularly, without using the computer or any other devices. You can get shinies without Pokesav! :)
