Hi all,

I'm posting a link to my channel where I'm recreating the GBA Golden Sun engine.

OpenGoldenSun Channel

Right now I have these videos up that show where I'm at with the engine.


It's currently not open source but the intent will be to open source it when it's reached an acceptable point. Subscribe if you'd like, I'll attempt to keep this post updated as I go. This has been made from the ground up with no RPG maker or anything.

I've described more details about the engine in this reddit post.

Let me know your thoughts.

Thanks for posting this!
I was thinking about maybe some day creating an open-sourced platform from the ground up based off of Golden Sun's code for people to create Golden Sun-like games... but I wasn't sure if I'd ever go as far as copying all the maps. (I was thinking more about a collection of code-based resources.) However, if it turns out your project is the perfect replacement (which it sounds like it is.) Then I won't need to...
Since I (and Salanewt) have documented quite a bit about GS2, I guess I'll eventually look into seeing how your project is organized compared to it, and check for consistencies as well. :)

May the force be with you!
Shoo! Why does it smell in here?
Maybe that's the wrong kind of force. *smirk*

I would pay good money for a decent RPG maker. I'm serious, too.

Though, for my own purposes, I would need 3D support and a Z-Axis to create something with an overworld style similar to Grandia. 3D Environments with 2D sprites. https://www.youtube.com/watch?v=sUUHBFN3QL4

I'd probably need for the battle system to be modifiable, so I could make something similar to Grandia, too.

Why am I basically asking for an Open-Source Grandia-maker on a Golden Sun Forum? >_<

I guess a guy could dream when wanting to make his own original RPG with inspired mechanics...

Question - how editable will this be?  Would we be able to add additional stats, so as to give psynergy stat support?  How much control will we have over things like critical hit rates, unleash rates, and damage formulas?

I'm really not the best person to do something like that and I really wouldn't have the time, sorry (also you can't afford me  Happy ). I'm really just making this because they're my favorite games of all time.

You would be able to do whatever you want in theory. I will most likely create all the damage and stat calculations off what the game currently does and then modify from there.

@3D support: Is it even possible to take Golden Sun's 2D maps and make them rotatable as if they were 3D? Even if it was a slight rotation like an earthquake. (Possibly using the height map in part of the equation of-course.)
It may or may not be tricky/ugly/feasible, but still, it was an idea.... You'd use sin and cos for sure. But just in-case, has anyone seen anybody try something like that?
@Ugly: Imagine how houses would work, you'd need to fix the sides and back, obviously.

Just to make sure, does some of that time you would need have to go into figuring out how to go about it, or would you already have an idea, but the work to do it is difficult?

Will we be able to manage things such as accuracy, evasion, and move priority?  Would we be capable of handling Criticals and Unleashes as separate entities, or would they be folded into a single thing like they were in Dark Dawn?

I like how you guys are already trying to hack an un-built project.  Happy

@Rolina, the thing with coding something from the ground up is, you can do anything you want.

@Fox, I'm really just going to focus on rebuilding the GBA engine as-is. I'm sure adding a pseudo 3D affect would be cool, but I'm not looking to reinvent the style of the game.

Looks sweet, you have the full attention of all members of this board!!!

This is the greatest news seen on this site in years!! I'd almost gave up on the idea of a golden sun Fan game.

WOW! Happy Joy

It's looking pretty convincing so far, I'm impressed with how well you've replicated the game's engine.

Thanks! I look forward to seeing where this goes.

I take that as a huge compliment, especially coming from you, so thank-you.

Okay, fair enough. Sticking to just the Golden Sun engine, is probably what I would have done as the focus point as well? ; And then when the GBA project would be complete, perhaps look to see what Dark Dawn had to offer, and implement optional things from there, but I dunno.

Looking good so far. Have you worked on the battle system yet?


Oh and...

Well, you are still limited by the programming language and hardware, but that's little to be concerned about considering how limited hacking the GBA was. (It's like hacking the GBA is only worth it for collecting data? That, and maybe translations/difficulty hacks, anything minor.)

Not yet, I think that will come later. Sorry, I know it's one of the more interesting parts but it's also one of the hardest. I'm comfortable with the structure I've built for doing field psynergy. While doing Move & Growth I think I was able to come up with a pretty decent structure so now it's just a matter of finishing up a bunch of the field psynergies. I'll probably focus on a couple more field related items such as: jumping, pushing, and cliff-edge sliding.

Once I'm comfortable with those items I'll move onto to either the world map or battle system. Once those are in a good spot, I'll probably do a major code refactor.

Here is a screenshot of the Class View for the engine (large image), this is completely subject to change and I'm posting this mostly because you seemed interested: http://i.imgur.com/xqeGWVm.png

That's fine. As a small hint, though, I believe the game uses two angle values that can be found at addresses 0x02030034 and 0x02030036. So I don't imagine that setting up the base battle system would be too difficult (Basically skin and bones), but actually making it a playable feature with properly working animations/etc might take a whole lot more work.

The World Map should be pretty easy...

That image looks great!  Keep up the good work.

KyleRunner: "difficult thing about the army": I'm very good at taking orders, so I don't have issues with autority or discipline. The most difficult thing is to be away from my family sometimes. I lived an entire year away from my son, so I'd say that was the most hard part by far. Now it's great!

January 25, 2018, 09:56:19 PM
Fox: Hard to explain without a diagram or something... but I could decide on that later. Right now, it turned out I dreamed of something! Something to do with going into the dark dimension... and to go between light and dark, required some energy (energy sphere/warp portal?) to be on... I forget most of the details of the dream now, but it's like you could get trapped in the dark world. Er...

Fox: Third approach idea = Scan char tables and set up an array that helps to quickly jump over bits that are scanned in the char tables.... to kind of mimic an actual tree a bit better/ and reduce unnecessary scans.).... (untested, but what to know what it's speed is like.)
