It takes a Riolu Egg a maximum of 6,400 steps to hatch however each Riolu Egg is different so it could hatch earlier depending on the Egg and other factors involved.
pay me
about 7,000 steps
Around 5,000 steps but each individual Pokemon has different hatching rates
It takes between 9,180 and 9,434 steps to hatch an Eevee egg. You can halve this time if you have a Pokemon with the Flame Body or Magma Armor ability in your party.
That dependes on what kind of Pokemon is in the egg. A good site to look how long it takes is: http://Pokemon.marriland.com/diamond_pearl/pokedex Just click a Pokemon or search one up and it will be there in 'steps to hatch'.
It takes a maximum of 5,120 steps for a Nidoran Egg to hatch however it could be less than that due to the fact that eggs are randomly generated.
It depends on what Pokemon will hatch from the egg. Different Pokemon need different number of steps to hatch.
A Pokemon adventure on Pokemon Diamond Verison can last forever if you wanted it to.
I tested it on my platinum game and it took me 11,475 steps to hatch my gible egg i don't know if its the same for dimond or pearl.
it counts what kind of Pokemon it is
A bad egg comes to be if you've hacked your Pokemon with action replay or something like that. It never hatches, and you can't battle or trade with your freinds
i don't have Pokemon emerald, but the answer is always the same. not how long. how many steps. walk ALOT and the egg will slowly start to hatch
