Secret Maryo Chronicles

Post by law56ker »

Secret Maryo Chronicles is an Open Source two-dimensional platform game with a style designed similar to classic sidescroller games. SMC uses the platform independent library SDL and the OpenGL accelerated Graphics Renderer for the best possible graphics quality.

I believe the source files are here, though i may be wrong.

Seems solid basically, but RAM might be an issue.

This seems like a very nice game. Sure would be nice to have this on Dreamcast!

OpenGL accelerated Graphics Renderer
That would likely hurt. We don't have anything resembling a real OpenGL implementation on the Dreamcast. That's partially because nobody's written one, and partially because the hardware just doesn't work the way OpenGL assumes it should.

Not to say it's impossible, but porting OpenGL games to the Dreamcast can either be very easy if they happen to use the subset of OpenGL we have in a way that the hardware can manage, or really hard if they don't.

Didn't someone have an open gl driver made for the dreamcast but they had a hard drive crash and lost it all. Well it was worth a try. I should look for some more sonic/mario engines and see if i can find any open source ones. I've learned that it is a good thing to look for Japanese/Asian sources and websites. There is a lot of games developed over there that you can't find easily unless you try.

What is the easiest type of game engine/code to port to dreamcast?

Isn't Secret Maryo Chronicles written in C++? I didn't think the DC supported that particular language. Of course, it's been a while since I paid any attention.

KOS is written in C, but that doesn't prevent programmers from using C++ in their programs. Some of the add-on libraries were written in C++, if I recall correctly.

Last week was my spring break, and I had some free time to mess around with the DC.

After just a couple days of conceptualizing and coding, I came up with this little Demo.
It is not a port of Super Maryo Chronicles source code. It is completely written by me, for the DC.

Features of this Demo:
-Multiple layers of Parallax Scrolling
-Animated sprites creating pseudo 3D effects
-Fast render using PVR hardware ~ 60fps
-Texture compression in the format PVR VQ to maximize VRAM and minimize CPU time
-Looping background music, in the format ADX
-NOT using SDL or any external libraries.

Good idea, I will look into that.

On a side note, I have implemented a simple map format that should make level editing a breeze...

Do you have a name for your game or you going to keep Super Maryo Chronicles as a main name ?
Do you plan to make a full game ?
P.S. Yep, a level editor in future would be nice.

P.P.S.
It is not a port of Super Maryo Chronicles source code. It is completely written by me, for the DC.
You mean Secret Maryo Chronicles?

Thanks for the interest guys, and thanks for the correction btw.

Secret Maryo Chronicles DC is the project name so far, would be nice to see a full game but I would probably need some help in converting the maps to the format I am using for DC, as it can be a bit time consuming.
If anyone is interested in helping, drop me a line.

The second demo is ready

If it doesnt require programming knowledge i can try to.
New beta looks awesome. I cant wait to see a full level. :)

+1 too :)

I also tried the demo, looks promising! What annoys me is the jump botton, atm you can't adjust it. I mean, it does not matter if you only push a bit or longer the jump button: it always jumps at the same height :-P

You could have a look at the source code of OpenGSS (a good clone of Giana's Sisters). I did the port to DC, and the code seems quite easy to understand. Maybe you just can copy some basic routines :)

PD: Buaaa, I want to take the coins!!! :-D
