FireRed hack: Pokemon FireRed Eternity [Completed]

[Elie1605]

POKEMON FIRERED ETERNITY

Update v3 - Released on November 12th 2025

​

---

♦ Introduction

This is an update of my previous Pokemon rom hack FireRed v514.
It is a remake of Pokemon FireRed, with only slight changes to the story.
This is not a difficulty hack. It is intented for casual playing, with a slight increase in difficulty in main battles compared to the original game.
The purpose is to have a fun (and not too crowded) rom which can be played differently every time thanks to having nice features and a large choice of viable Pokemon and starters.

♦ Features

I'm not sure I understand what you mean. If it is "Playing the game a second time" then no, but you can very well trade with your previous saves, or you can use Nuzlocke for an additional challenge. Anyways, hope you enjoy it!

 

[DeShawn]

Can you please tell me what are the shiny odds

 

[Elie1605]

Can you please tell me what are the shiny odds

Shiny Odds = 1/512 without the Shiny Charm, 1/170 with the Shiny Charm
Also, using the DexNav in a chain increases this chance.

 

[Fleshreaper]

I just beat Brock and was told I was give the DexNav by the Aide, but it's nowhere to be found?

After beating Brock, go in the direction of route 3 and the Prof. Aide will give you the DexNav :)

No, I mean I did that but I'm not finding the DexNav anywhere after that, it's very strange O.o. I'll play a little farther and see if it works out

 

[Fleshreaper]

Trying to myself, nvm, I'm dumb, I just needed to move to the right on the menu, I got it :p.

 

[Elie1605]

Oh. That is explained in the FAQ. Press Start -> Right Arrow -> DexNav. Then R to choose a Pokemon. Then in the wild you press R again to search for it.

I appreciate that, I didn't see the FAQ, apologies! I wouldn't have bothered you otherwise <3. I'm liking the rom at the very least, it's been a long while since I've found one worth diving into and I think you got me playing this one through!

I'm tempted to ask where the exp share is but I'm hoping I'll find it in the FAQ that I'm about to read!

Edit: Yup, Rt 10, on we go

Hello NG TOKYO, I don't mind. I will send you anything you need. Let's speak in private 🙂

 

[JamesNorritom]

Do you have any plans to add cheat functions to the game such as "easy catch" and "easy candy" for players who just want to do a nuzlock challenge etc.
Your hack looks so damn awesome. I can't wait to play it!!

Hello there,
No, I'm not planning on adding cheats (and I don't even know how to do it lol).
Hope you enjoy it!

 

[alpha001]

Looks fresh, hopefully no need for power level crazy like other ROMs. 😅

 

[raul_pchn]

Looks great, a good mix, just a question... is there an EV "scan" or an extra page on the stats to show details on EVs?
*First post here*

Not in the Pokemon menu.
But you can talk to the EV Master in Cape Brink to know and reset your EVs.

 

[Julix]

First post here. I enjoyed the game a lot and I am now in the post game. I am trying to beat all the Gymleaders for a second time. Just my pokemon are a lil bit underleveled and I need to train new pokemon for the different Gymleader teams. Is there a way to lvl up "quickly" or an easier way to lvl up than to do the Elite 4 over and over again or battle with the Vs-seeker?
