You just need to level it up a bit and it will evolve.
Either level all your Pokemon to level 100, explore and discover cool places, battle against friends and rivals, or start over.
Nothing special, but if you migrate them over to Diamond, Pearl, or Platinum, when they are at the same level, you can get Regigigas.
You can get Rampardos by evolving Cranidos. you can get Cranidos in the Museum in Oreburgh if you hand over a Skull Fossil to the cientist. Cranidos Evolves at the Classic Fossil Evolution level, like all the other Fossil Pokemon, it Evolves at level 40.
Just keep on playing the second level over and over. It worked for me. I am still leveling them up for the Gym though. I can't get past Brock:( It's too hard. Try evolving Kakunas and Metapods you can catch at Viridian forest.
You must... A.Trade Over Wifi B.Tranfer it over from Ruby,Sapphire or Emerald (after evolving it first)
you have to battle against other Pokemon that are level 100

Just do the Pokemon League over and over
if you want to level up your pokemon faster. give the pokemon you want to level up an exp share but it at the bottom of your pokemon list and battle and beat the elite4 in succession over and over until it is at the level you want it to be.
no
The only way to acquire a Raichu in Pokémon Yellow is from trading over another Pikachu and evolving that or by trading over the Raichu.
There is no such code for that. The game can only allow you to have Pokemon up to level 100. No Pokemon over level 100 exists.
