What the heck is Spectrobes?
Spectrobes was a sci-fi monster-battling RPG published by Disney Interactive Studios. Released on the Nintendo DS, the game was praised for successfully combining the monster-collecting genre with its sci-fi tropes, including space travel, planet exploration, and an extraterrestrial foe, while maintaining the JRPG base that supports monster catching. Its primary features included excavating and unearthing fossils of extinct creatures and reawakening them to fight alongside you. These entertaining tropes, combined with unique creature designs, gave Spectrobes its own stage to stand on. The game was considered a commercial success and spawned two sequels, before quietly being dropped by Disney and forgotten about over the years.​

What the heck is this rom hack?
This project aims to recreate the original Spectrobes game, but within Pokemon FireRed. To most of you, this can just be considered a fakemon or un-pokemon rom hack - but not one which follows the standard tropes of Pokemon. While based on FireRed, the uniqueness of Spectrobes means that this project is an entirely new experience than that of mainline Pokemon games. Even if you haven't heard of Spectrobes, if you're a little tired of the Pokemon story formula and are looking for a fresh monster-collecting rom hack, this one aims to please you too! And to the few of you who are already fans of Spectrobes, you can consider this a nostalgia-loving GBA demake of the first game :)​

What the heck is the story (brief intro, no spoilers)
Rallen and Jeena, Planetary Patrol officers, are sent to investigate a crashed escape-capsule and inside it find an aged survivor of a now-destroyed star system. He explains that his civilization was destroyed by amoebic-like creatures called Krawl who devour planetary systems throughout the universe. He then explains that the only way to fight them is to reawaken their natural enemies - the Spectrobes. Rallen and Jeena, hoping to protect their own star system from this fate, set out to gather as many Spectrobes as they can and find the source of the Krawl swarm.

What the heck you'll be doing
The primary gameplay feature of both the original game and this Rom Hack involves you progressing through the linear story and using your spaceship to travel from planet to planet. Every planet has different environments, with different Spectrobe fossils to awaken and different Krawl to fight. Train up your team of Spectrobes and follow the central plot in a very story-driven game, all while learning as much as you can about these creatures and exploring all the different biomes in the Nanairo star system.

What the heck kinda monsters you'll be collecting

What the heck you'll be listening to

The music of the original Spectrobes game was loved and often praised as one of its best parts. It's also just a nostalgia trip for me, so I'll be doing my best to port over every single music track into GBA formats and fit them in this Rom Hack. For Spectrobes fans, this should hopefully tickle your nostalgia as well, and for everyone else, you can enjoy a Rom Hack with completely new music instead of the regular Pokemon tracks :)

I'll probably upload the soundtrack here for people to listen to later.

What the heck kinda core mechanics exist

Everything is this section is subject to change.

This is where we get to unknown territory. There's a lot of variability that comes with porting a real-time DS action game into a turn-based GBA game, so please leave feedback as to what gives the most fun experience.

Battle System

Moves and Types

The current plan is to make the battles more interesting/reminiscent of Spec1 by giving every Spectrobe (and Krawl) species completely unique moves. These "signature moves" will allow every Spectrobe to be useful. A number of basic moves will also be shared between species. The only things the player will currently have to pay attention to with moves is Effect, Power, Accuracy, PP, Targets, and Type, with few moves giving stat boosts and even fewer giving status effects until later in the game. This is to remove some "pokemon-ness" from the system. That doesn't mean that every Spectrobe will be stuck as generic damage-dealers, but does mean that other fight styles will be a little rarer than in Pokemon, and limited by species, hopefully ending up keeping a similar mix to that of Spec1.

The types, Corona, Aurora, and Flash, will be unchanged from Spec1.

STAB has been removed as it has no place in a game where monsters learn moves of one of two types.

Additionally, the physical/special split has been implemented to give more range as well.

I believe these changes will keep to the spirit of the original Spectrobes but still work in a turn-based strategy environment. That being said, I am completely open to changing these things entirely if it is unfun or too easy, or anything really. So please leave feedback!


Synergy

Included as a nod to the "Beyond the Portals" mechanic where certain Spectrobe species have a unique combination attack and as a replacement to Pokemon abilities. This mechanic will be expanded upon in comparison to BtP, with many more species combinations planned to be included in future. Simply, compatible Synergy Combos receive a 50% offensive boost in double battles.

Vilamasta + Bartolor --> Armored Bulk

Komanoto + Shimanoto --> Guardian Dogs

Naguryu + Grilden --> Draconic (Grilden not obtainable in this version)

Field

A few things to note outside of battle:

You always need a minimum of 2 Adult Spectrobes in your Prizmod, as opposed to 1 Pokemon. This is a nod to Spec1, and is also because double battles will become the most common form of battle as the game progresses. Still, you won't white out unless all your Spectrobes are defeated (but you may be prevented from progressing).

Fossil locations and Vortexes will respawn when you leave an area and return. Minerals and Cubes will not respawn like this (but old Mineral locations may respawn as you progress through the story).

Child Spectrobes can't be sent out in battle. The game will ignore any Child forms in your party. You can't use them as fodder to heal your Adults and you can't switch-train them until you evolve them. But there's still a reason to bring some Child forms with you:

The purpose of having Child forms right now is to hunt for Rare Deposits. These are found in precarious locations, and Child Spectrobes with unique attributes (such as being able to fly, having a hard outer shell, etc) will be needed to get the goodies inside. They will contain a lot of minerals, but also a Secret Spectrobe fossil - a fossil of a Spectrobe from Beyond the Portals, not Spec1 - that can't be found anywhere else, so any collector should look out for them.

I've updated the game with one of the franchise's major mechanics, Excavation!

Since this is such an important feature that I'm downsizing to the GBA, I'm releasing an update specifically adding this so that we can all see how this style of excavation feels.
This is a test phase of this mechanic so let me know what you think! Download the game at the automatic patcher here

Amazing work! I remember the first and second games fondly, except for the first game not having respawning minerals...

I remember my favorite being the purple sword whale. Obtained very early on and poured all the minerals I could into that one.
 
Oh My. Not only has someone other than me heard of Spectrobes, but you've gone and made this absolute love letter to it! The UI looks gorgeous and well-adapted, and I love how much of the original game assets you were able to carry over. I can't wait to get into this. Bravo, Asith! I am a longtime lurker dev, and finally registered an account just to say thank you.
 
Game has been updated to V0.4.2 , a minor update featuring various important bugfixes and improvements. Can be downloaded here or on the automatic patcher!

First post has been updated with links
 
Oh shit, I remember playing the original ds but this fan game recreation in pokemon... I'm definitely waiting for the full game!
 
The game has been updated to V0.4.3 which adds a fully custom sprited roster!
