Aridia

Introduction

Many consider Phantasy Star III for the Sega Genesis to be the "black sheep" of the series. Personally, I'm a fan of the game but also acknowledge that it's not perfect. If you're one who thinks they can improve upon Phantasy Star III then here's your chance to finally prove it..

Aridia is a rom editor for Phantasy Star III. It has a mostly-friendly interface that makes editing incredibly easy. No messing with hex editors, decoding values, or any of that. If you can click and type then you can hack away to your heart's contentment.

Contributing

Aridia was not a solo effort, well the coding was but not discovering the myriad of things that can be edited. I am always looking for contributions, even small ones. If you'd like to pitch in, here are some items I'd appreciate help with:

Palette Identification - If you've seen the palette editing screen then you've noticed the large number of unidentified palettes. I'd love to track down what each one is used for. Gens KMod is pretty handy for this because it can display the palettes currently loaded. From there, it's a brute force effort to match them to one of the unidentified palettes. They tend to be grouped together so it's not extremely difficult to do, just time consuming.

Finding New Stuff to Edit - If you can figure out how to edit something currently not supported in Aridia then I can probably figure out how to add it to the UI. For example, I have a pretty good idea where the map data is stored but haven't yet deciphered how it's stored. Once that is determined, creating a screen to do the actual editing is probably the easiest part.

Testing - I'm actually quite happy to get bug reports. I'm certainly accident prone and would like to know when something isn't working or is producing a result that just doesn't seem right. .

So what's in it for me if I contribute? I can't offer cash or fabulous prizes. You will have the honor of appearing in the credits though. There's also the satisfaction of working on what I intend to be the best ROM editor for any game. Well, at least the best ROM editor for a Phantasy Star game. Failing that, the best ROM editor for Phantasy Star III.
