Description

Pokemon Emerald Imperium is a difficulty/QoL hack of Emerald that is fully complete and beatable through the Champion battle with some post-game content.

My goal in creating this hack was pretty simple: I wanted to create an experience in Emerald that is as close to the experience that Pokemon Radical Red delivers as possible by porting all of the balance changes from RR into a new game and by creating a whole bunch of new battles with increased difficulty. These balance changes include new abilities, stat changes, type changes, learnset changes, evolution method changes, etc. I want to be clear here that I am NOT affiliated with RR in any capacity; I am merely a person who has spent many hours playing RR, and who, like many other romhack players I’ve encountered, wished for more games just like it in other regions. I want to give full credit to its creators for all of the ideas behind the balance changes mentioned, QoL changes, and many other features that I brought over into this game. With all that being said, let’s get into the features and changes you can find in Pokemon Emerald Imperium!

• Playable Pokemon from Gens 1–9 (almost all, minus a few Legendaries)
• Modern Battle Engine with advanced AI and mechanics

• Built-in Randomizer – for Pokemon and abilities, fully customizable
• Mega Evolution, including new custom Megas like Gen 4 starters
