emeraldpartyrandomizer's Introduction

Pokemon Emerald Party Randomizer

This is a romhack for Pokemon Emerald that randomizes your party's pokemon at the beginning of every battle; each pokemon in your party becomes a new pokmeon chosen randomly from every pokemon in the game. It preserves EVs, IVs, contest conditions, HP percentage, XP percentage, shiny/pokerus, and nickname across randomizations, and the moves of the new pokemon are the same as if they were found in the wild at that level. Pokemon will also be added to the pokedex if you get them through randomization. I made this romhack for SmallAnt to stream by request. You can watch him play it here.

Downloads can be found on the releases page of this repository.

Installation & Use

The hack is distributed as a .bps file used to patch your Pokemon Emerald ROM. You must acquire a Pokemon Emerald ROM to use this romhack; the patch file only contains my changes. .bps patches can be used with a patching tool called Flips or directly inside some emulators. The ROM to patch is release #1986, which should be Pokemon Emerald U/E. The correct ROM should have the SHA1 checksum f3ae088181bf583e55daf962a92bb46f4f1d07b7 if you want to check that. After patching your ROM (either by creating a new file or in-emulator), the randomizer will just work!

About The Code

This randomizer works by modifying the code that's called at the beginning of every battle. In the pokeemerald project the function that's modified is SetUpBattleVarsAndBirchZigzagoon in battle_controllers.c. All it does is call my custon function rndParty if the check for being the first battle fails. Note that all the code is marked as static methods -- this is on purpose to make compilation easier by avoiding introducing another file to link, since the setup can be a little precarious.

emeraldpartyrandomizer's Issues

Issue with Patching

When i patch the emerald #1986 file with this patch it says it cannot because i am on read only however i don't know how to fix that.

Rom #1986 Is not Randomizing

I downloaded the rom and the randomizer, but when I load the game it doesnt randomize my party. I tried patching the rom but it wont do anything. It says that it can not find the patch file. Please help. I really want to use this mod. It looks like so much fun.

Visual Boy Advance doesn't open the rom

I have a problem were the emulator doesn't open the rom with the patch and just says "Loaded battery" to then turn all white.
Any help?

No Ability

This is only going for this specific pokemon, the ability is just nothing.

This has nothing to do with this hack

I found this page after watching Ant's video.
I wonder if you would consider doing a commission job?
My wife's birthday is coming up and she loves pokemon crystal.
I modded a GBC with an IPS screen so that she can play in the evenings.
She mentioned in passing that it would be cool to have every pokemon be available in the wild everywhere.
I thought it would be a great birthday present for her to hack Crystal for her, but man the learning curve is steep on this one and I don't think I have time to figure this out in time.
I have no idea how much time this would take but I'm willing to pay for your time. I'm not sure the best way to contact you but if you wish you can always shoot me an email at dadderulez(at)gmail.com

Some thoughts on the hack;
All pokemon should be available everywhere - I'm thinking all the pokemon that normally spawn in that area have a higher chance of spawning and the rest of the pokemon would have a low chance. That would kind of make sense maybe? They should also be the same level as the pokemon in the area I think. On second thought, perhaps pokemon that normally only spawn in water shouldn't spawn on land and vise versa :D
It would be cool if the title screen also said: "Johanna edition" or something similar. (Johanna is the name of my wife)

Shiny status not kept.

Wanted to let you know that the shiny Pokémon I caught does not stay shiny after being randomized.

Randomizer for spanish

Is there any way to make it work in a spanish rom?
It would be so useful

Does this partyRandomizer also work for EmeraldRomHacks

Does the checksum need to match, or could this also be done for romhacks, which aren't to different from the original emerald rom ?

Patch is .c file

I have FLIPS and LIPS, but when I unzip the file the patch is a .c file instead of .bps or .ips. I think I am missing a step and can't figure out what to do next. Any help would be great. Thanks!

Hardlocked in Sootopolis

I've gotten softlocked due to not being able to use HMs a lot but it's usually not a big deal because you can either start battles until you get a Pokemon on your team that can use the HM you need or worst case scenario you can reset the game. However, I think I've gotten myself permanently locked in Sootopolis City. I entered Sootopolis through the underwater cave and I saved inside the city because I thought it was a good natural stopping point to get off the game. When I got on the next day I realized that by the time I got there my party had changed and I don't have a Pokemon that can learn dive to go back. I also do not have a Pokemon that can learn fly. I can't go into the gym to start a battle to get a new team since the doors are locked and I don't think there are any wild encounters either. And I know this is my fault for saving in the city but is there any way I can leave the city and continue to progress through the game, or am I permanently stuck.
