Pre-Patched Pokemon Radical Red GBA ROM Hack Creator: Yuuiii Version: 4.1 Hack of: FireRed Updated: March 23, 2024


I’ve been playing Pokémon ROM hacks since I was a kid, beginning with Quartz, Ruby Destiny Reign of Legends, and Shiny Gold, all of which fueled my obsession and turned me into a community lurker for a long time. Although I attempted to make one myself, I simply lacked the necessary knowledge and dedication. Now, around 10-12 years later, having seen how far ROM hacking has progressed and having gained more confidence in my abilities, I’ve decided to revisit developing my own ROM hack.

There’s no shortage of fire red enhancement hacks these days, so you’re probably wondering what this one has to offer. Personally, I prefer difficulty hacks, which is why I consider Clover and Vega to be the best ROM hacks available.


This hack is at its core a difficulty hack with additional features; quite similar to Drayano60’s enhancement hacks, which provide access to nearly all the Pokemon while also adding relevant buffs to make all sorts of different Pokémon and playstyles viable, and with an insane amount of quality of life features added that also make many gruesome tasks far less tedious

This is a collaborative project between me and a friend koala4; while I’ve handled the majority of the technical aspects, he’s been invaluable in balancing, making suggestions, doing the majority of the wild Pokemon locations, testing, and more.


This hack utilizes the Complete FireRed Upgrade engine (!!!!) and Dynamic Pokemon Expansion built by Skeli789, Ghoulslash, and others. It’s responsible for most of the significant features in the hack; I’ll list the important ones below.

Provided by CFRU & DPE

  • Physical/Special split + Fairy Typing
  • All Pokémon up to Gen 9 are obtainable (with some exceptions, see further down)
  • Moves up to Gen 9, including some of the Isle of Armor DLC moves!
  • Updated Pokémon sprites
  • Mega Evolution
  • Abilities up to Gen 9
  • All important battle items (with some exceptions)
  • Raid Battles
