Pokemon Emerald Double Up Delevelled ROM

Pokemon Emerald Double Up Delevelled is a GBA Rom Hack by AlmightyK based on Pokemon Emerald in English. It was last updated on March 27, 2024.

Introduction

Pokemon Emerald Double Up Delevelled is a vanilla+ rom hack of Emerald that applies the standard Battle Engine upgrades while also changing to double battles and making Pokemon stats independent of level. It is a new challenge on an old framework that should make an interesting replay.

KNOWN BUGS

• Pokedex shows Shiny sprites
• Leaving the Move Swap menu without learning a move puts the pointer on the menu of the last Pokemon that used Move Swap
• Pokeballs will sometimes fail in Double Battles, unknown why.
• Hyper Trainer doesn’t check if Pokemon already has been Hypertrained, you can waste money doing this
• Flutes consumed if used during battle
• Castform Form Change doesn’t work with existing weather
• Move Summary in battle crashes at Battle Frontier (Fixed I think)

LEVEL REMOVAL

• One of the key features of Double Up Delevelled is that Level is no longer a factor when determining a Pokemon’s stats, with the exception of HP. Now Stats are at a set value based on Base Stat, IVs, and Nature. They will be altered as EVs are gained.
• Level is now more a representation of the state of training, as it still affects the moves a Pokemon knows, the effects of level based moves (such as Seismic Toss), when a Pokemon can evolve, and does make them slightly tougher increasing Max HP by 1 per level gained.
• Damage also no longer scales based on level.
