Description

Pokemon Emerald Imperium is a QoL / difficulty emerald hack with a slightly altered story that is fully beatable through the Champion battle (and has a little post-game). I’ve also added some characters from Gen 4, namely Dawn as an additional rival throughout the game, all the Gym Leaders as optional trainers to fight (except Roark, he’s mandatory), and more!

Other notable features and additions include a built-in randomizer, a couple of difficulty options (just Easy and Normal for now, maybe I’ll add a Hard mode in the future or something), several new Mega evolutions, including all the Sinnoh starters, and a whole lot of balance changes to various mons. It’s also got every QoL / feature branch under the sun in there somewhere, so I won’t list them all here.

I’ll probably come back and edit this message at some point to include links to the docs and other things that I’m still polishing up, which will list everything in excruciating detail. I’m sure this game won’t be many folks’ cup of tea around these parts, but I still wanted to post it because I am happy with myself for sticking with this for so long, making the game that I wanted to make, and getting it to a place where I am comfortable sharing it with others.

Also as you will see in the credits, many of your guys’ assets, features, and ideas are in the game somewhere, and I definitely would not have stuck with this project for so long if it weren’t for the homies here, so it is definitely a community hack in that sense.

Features

  • Almost all Pokemon from Gens 1 – 9 available

  • Modern battle engine

  • Mega Evolutions, featuring new custom Megas added for several Pokemon including Gen 4 starters and several Gigantamax forms converted to Megas

  • Several Gen 4 characters added, including Dawn as an additional rival, all the Gym Leaders, and more!

  • Increased difficulty of trainer battles, with focus on Gym Leaders/Elite 4, Rivals, Team Aqua/Magma battles, route Mini Bosses, and optional Mini Bosses

  • Several other optional Boss Trainer battles (with hopefully good enough rewards to incentivize the player to actually want to do the battles) 

  • Configurable Minimal Grinding Mode

  • Built in Difficulty Modes: just Easy and Normal for now

  • Built in Randomizer with configurations for species and ability randomization

  • Built in Level Caps

  • DexNav

  • Balance updates for Pokemon to match RR, which includes type-changes, stat updates, ability updates, learnset updates, etc. The goal for this was to be able to reuse the online RR dex and the RR damage calculator.

  • Small story tweaks, mostly with the goal of lining up difficult battles

  • Not needing to teach HMs to use them, and they are forgettable if taught

  • Reusable TMs

  • PokeVial with infinite uses to heal your party from anywhere

  • Access to the PC from anywhere

  • Stat Editor (for EVs and IVs) given in Mauville

  • Toggleable following Pokemon, Auto Run. and Infinite Repel

  • Hold R to speed through NPC dialogue

  • Option to relearn level-up moves and egg-moves for a Pokemon in the party menu

  • Move-tutor moves converted to TMs so they can be taught anywhere, no more move tutors in game

  • Item care packages

  • Ability Capsules and Ability Patches to easily change between abilities for a Pokemon

  • 2nd Nurse in every Pokemon Center who can:

    • Change Pokemon’s natures

    • Swap genders for Pokemon with gender-specific evolutions

    • Set Pokemon directly to the Level Cap

Known Bugs

  • Some of the color palettes of the follower Pokemon have issues being on screen at the same time as some of the custom overworld sprites. The example I have come across is Charmander or Gardenia’s palette not loading correctly, depending on which one is loaded on screen first. In theory, one specific follower probably causes the same issue for each of the custom overworld objects, so if you find another example of it please let me know!
  • Some shiny overworld Pokemon do not display correctly (you can fix this easily by opening the party menu, bag, or some other menu)
  • While not technically a known bug, my goal was to match the data for each Pokemon found in https://dex.radicalred.net/, and I am sure I missed some things (especially learnset data), so please report any inconsistencies that are not documented as intentional changes!
  • Pomeg Berry merchant and some other mart workers can crash the game on MyBoy emulator.
