Pokemon Sapphire Questions

I used a Action Replay code to get pikachu that I just got today and all I got was something called a bad egg.
<BR>
<BR>What does this mean? what will it be? I'm very confused.

I have a great idea!!!!

I think I know what the problem is!! It's either:

A. Bad eggs are the shiny form of the original egg. I think since egg-hatched Pokemon you have made by breeding Pokemon have preset average IVs and stats, if the first Pokemon you get out of an egg by the breeding of your own Pokemon is not shiny, then you will never find a shiny out of an egg (unless you recieve one through a special event, or if you restart your game a try to find if breeding will give you a shiny.) When Action Replay is designated to encounter shiny Pokemon as well as eggs, then you have a glitch on your hands-- since the game has already set the average on the egg's stats, your pushing the game to rearrange the averages, and that can screw-up your game.

or:

B. Bad eggs contain glitched Pokemon, like Missingno.

or:

C. Bad eggs contain Pokemon that are created through the mixture of the two Pokemon used in the breeding.

or:

D. Do any of you know about PokeRus*? It was a virus your Pokemon could catch from wild Pokemon during wild battles-- this feature was only available in G/S/C. You had a 1 in 8156 chance to find these viral Pokemon, the same size in chance to find a shiny Pokemon. I have Pokemon with PokeRus-- but know that PokeRus was good. I wonder if that is what makes a Bad Egg, PokeRus...
* PokeRus is short for "Pokemon Virus".

or:

E. A Bad Egg contains Legendary Pokemon. Legendaries don't breed, hence.

or:

F. It is the form of Missingno-- in the indentity of and egg?!

Try these. It should help!
