Here's why:
* No Duplication Glitch: FireRed lacks the common "duplication glitch" found in other Pokémon games. This glitch typically involves manipulating the game's code to create copies of items or Pokémon.
* No Trade Evolution: Eve doesn't evolve through trading, so that method of duplication isn't available either.
However, if you're looking to obtain multiple Eevees, there are a few options:
* Breeding: You can breed two Eevees to get more Eevees, but this will take time and effort.
* Trading: If you have friends with FireRed, you can trade Eevees with each other.
* Using Emulators and Mods: If you are playing on an emulator, there might be mods that allow for duplication. However, this is not a legal or officially supported method.
It's important to note that duplicating Pokémon or items is against the spirit of the game and can ruin the experience. It's always best to play the game fairly and enjoy the challenges it offers.
