It actually tinkers with many other aspects of the game too. While the main aspect of this has to be the way it randomizes the Pokémon.
The actual Pokémon themselves are changed to ranging from their move’s stats, pallets and so on. If you have played the heck out of Ruby, Sapphire and even the original version of Emerald then you will certainly like how this keeps you on your toes. This little bit of unpredictability really does make the game that extra bit exciting. This program will randomize the starter Pokémon and the items they have! It will also randomize all of the other Pokémon that you will encounter in the game so you never know what the heck will show up and where.
Once you have installed the Pokémon Emerald Randomizer you will notice that things are different.
