- a modern rpg in a retro cartridge -




You awake at an overgrown altar

around you nothing but darkness and shadowy figures

Beyond the darkness lies an old castle surrounded by dark fields

and inhabited by an evil king

An adventure awaits and your story begins here






[td]RPG in retro GBA cartridge

This project is all about creating a modern RPG in a GBA cartridge.

The game will be a modern themed RPG with old school graphics

so that it can run on an old Nintendo handheld.


Developping GBA roms is a whole new challenge since the consoles are discontinued.

The graphics will also have to be simple enough for a GameBoy Advanced to run it.


Targeted platforms

The targeted platforms are any platform that can run a GBA cartridge.

Originally, only the cartridge will be released, so the game will be playable on any console

ranging from the GameBoy Advanced to the DS lite.


The limitations of GBA developing

Since the GBA rom should run on the lowest compatible handheld, being the 

GameBoy Advance, you are limited to a 32-bit ARM7tdmi RISC CPU operating at 16.78MHz

along with regular 32-bit ARM instructions and 16-bit Thumb instructions.


This limits your game to basic graphics and the maximum size of your game is limited

to 32 MBit once it is fully compiled.


How GBA developing works

GBA roms are written in C and then cross-compiled into Thumb commands which

the GameBoy can understand. This means that roms can be relatively easily made in 

C language.


Current status

At the moment the project is still in a very early phase. We are still working on

game concepts and are 'reinventing' GBA programming, since this isn't done

anymore and documentation is limited.


We will keep you posted about the status of the project and you can

also submit ideas and feedback.


Help the project

Are you good with C/GBA programming or are you good at making artwork

for games? We could always use more help to improve our project, so if

you are interested and you would like to help the project,

please contact us![/td]

You awake at an overgrown altar and lear that you were summoned

by the shadow people who have been living underground for years

and see you as a deity. You are in fact not a deity, but just a simple

boy from the overwold. Still, the only way out of this is to

overthrow the evil king who has been supressing the shadow

people for years, but the king has many minions ready

to stop you. It turns out that brute force is not always

the best approach and that your actions will

determine the outcome of this story



You will advance your adventure by overcoming minions and bosses

with the help of the shadow people. There are multiple ways

to do this however, instead of using brute force you can always use

a more diplomatic approach. This and many other choises you will have

to make will effect the outcome of the game[/td]

-        Do you like this concept and would you like to have the game once it is finished?        -

Retro/Homebrew is always intellectually interesting, but its something people do more for the love and experience of doing it, rather than hopes of commercial success. Its interesting hardware, with features and limitations that can force your hand to deliver some really inspired solutions -- it and the dreamcast are usually the platforms I recommend for those interested in retro homebrew -- either platform is limited enough to prove a challenge, but capable enough to do interesting things; old enough to communicate the essence of old-school, to-the-metal development, yet not so archaic or downright weird that the lessons you'll learn won't benefit you in contemporary times -- they will.


Good luck, the GBA is an excellent platform for retro-styled RPGs.
