To tell you
...I'm sorry but the code website is private
You can't you must trade from Emerald, the Lost Cave is programmed to have mareeps but it's an event that Nintendo never had
Since you can't get mareep in firered trade one from emerald.
ampharos you mean right, well you can't unless you get a mareep from emerald.
Ampharos do not naturally appear in the wild in, so in order to get an ampharos, you will need to evolve a flaaffy. Flaaffy can be found on Route 42 and Route 43 or evolved from Mareep, which can be found on Route 32, Route 42 or Route 43.
You cannot catch an Ampharos in the wild, but you can catch a flaaffy in the grass on the way up to the lake of rage (which is above Mahogany Town) and level it up. It evolves on level 30.
If you mean a wild one you cant find. Try catching a mareep (on routes 32, 42 and 43) or a flafly (on routes 42 and 43) and evolve it to Ampharos (lvl 30)
No.
In the wild.
Ampharos does not evolve.
You cant only through hacking.
Vaporeon does not naturally appear in the wild in Pokémon FireRed, so you cannot catch them from the wild. However, you can obtain a vaporeon by using a Water Stone on an eevee.
You can get it by evolving your mareep into a flaffy, then a flaffy into an ampharos.
