I wrote a metroid model-viewer over Christmas (I was pretty bored and my DS hasn't arrived yet), it was a fairly pointless exercise but it showed up a few things about the hardware.
If anyone wants a copy then PM me (I haven't got any webspace to host it); it would probably be useful to anyone writing an emulator since models are basically raw register write lists.
#32781 - Roamin - Mon Dec 27, 2004 9:12 pm
Thanx for the proggie , most models are viewable.
The e3 level crashed the program :(
Still .. nice to see people can work that fast during holidays
Keep it up!

How did you extract the metroid model? I really would like to try it out =)

darkfader.net has the tool you need , ndstool.exe , but you will still need cygwin1.dll (i tried 4 versions before i got one that worked)

Roamin, could you link to the version of cygwin1.dll that worked for you? I've tried a couple myself to no avail.
#32865 - tepples - Tue Dec 28, 2004 9:44 pm
In order to use a program that depends on cygwin1.dll, you need Cygwin and the program's source code (to recompile it against your Cygwin installation).

W00t. Sorry for the useless post, just excited that I finally got it to work... :-P
#32872 - SmileyDude - Tue Dec 28, 2004 10:10 pm
heh -- at this point, I would think that the Metroid demo cart image has to be one of the most analysed ROM dumps ever. Pretty neat stuff seeing the models extracted from there :D

I've tried this program and it works great. I think this is a really good step towards homebrew on the DS. Great job on the program it works perfectly, though I can't load the e3 level either.
#32916 - ravuya - Wed Dec 29, 2004 5:40 am
It built fine under Mac OS X with XCode, but I haven't been able to find a model to try it out with. I guess I may have to find a spare demo card and make a card dumper.

anyone (perhaps ravuya?) who has XCode that can build it for me?
thanks
#32951 - SmileyDude - Wed Dec 29, 2004 5:13 pm
i was able to build it for Linux (Fedora Core 3) by making a few small changes to the source:
change #include "glut.h" to #include <GL/glut.h>
change main() to return an int, and add a return 0 to the end of the function.
compile with g++ -o dsgraph dsgraph.cpp -lGL -lglut
seems to work good, but I get a segmentation fault on some files (sorry, haven't made a list of which ones it does it on)

Neither the PlayStation nor the Nintendo DS has texture filtering except possibly by jittering the texture coordinates frame-to-frame.

While most of the time when the program crashes it's because you loaded an animation or some other unsupported file, some of the files I'm at a loss for. Like metroid_Model.bin. Sounds simple enough, but the model viewer crashes....

It just looks so "bleh" when you blow up the size of the models on a computer screen. Though scaled down and in motion, they look decent.

'F' toggles texture filtering. It's off by default because that's closer to what the DS does.
Other keys are 'W' for wireframe, 'C' for vertex-colours, 'T' for texturing and 'B' for backface-culling.
As regards the crashes, I was a bit drunk when I wrote it so it's no doubt quite buggy (although I've never had a crash myself with a *_model.bin file). It's not meant to be a fully-featured app, I wrote it more to explore and document the DS display-list and texture formats.
#33004 - abilyk - Thu Dec 30, 2004 1:06 am
I played with it a bit last night after recompiling ndstool to work with my Cygwin setup (thanks for the tip, Tepples). The program is great, Mike. I'm curious to see your documentation regarding the model formats. Do you plan to release it to the public anytime soon?

There's no documentation, I meant that the source itself documents the texture/dlist formats a little. If you're *very* curious, the code to parse models lives at 0x0201BB48 in the metroid arm9 bin. Pretty dry stuff though.
#33015 - ravuya - Thu Dec 30, 2004 4:20 am
Trying to port this to Mac OS X, but there's so much endian crap I'm not sure if I'm up to the task.

i just did a quick look at it with gdb under linux, and it seems to be crashing when it tries to create the window. Why for some files and not for others is what's confusing me. I see that the loading is being done before hand, but nothing appears to be off -- unless you're corrupting the stack somehow....
anyway, here is the output from gdb...

The answer is probably simple: Either A) Some models are different formats, B) Some models are compressed, C) Only models of a certain size work in the viewer or D) Some models use a palette of some sort that the viewer can't handle.

A much easier alternative to cygwin is MingW http://www.mingw.org/
It has gcc and all other tools but will compile real executables for windows no dependencies on cygwin dll's.
That's what I used to compile ndstool and I'm could give it to any windows user and it wouldn't need a cygwin dll. It's also a lot less to download than cygwin.
I just thought I'd throw that out there if some people are thinking they need to install cygwin, it might be easier to just install mingw.

If someone wants to compile ndstool under VC++ .net 2003, change few things:
- remove #include <sys/types.h> and #include <sys/stat.h>
- add #include <direct.h>
- change mkdir(strbuf, S_IRWXU) to mkdir(strbuf)
- change mkdir(extractdir, S_IRWXU) to mkdir(extractdir)
and that's all ;)
// EDIT: Also works on Dev-Cpp (tried ver. 4.9.9.1)
// if there is error with MAX_PATH, just comment line #define MAX_PATH 2048

How do I get the models? I have ndstool but what do i need to extract them from the game? Cables?

You need to extract it from the ROM.

You need rom and ndstool. Then type:
ndstool.exe -x rom_name.nds output_directory
in command line or console, and you get all files - models are in models and levels subdirectories.

That's strange, both of those models work for me. [Images not permitted - Click here to view it]
Perhaps it has to do with your Cygwin setup?
On another note, does anyone know what program is needed to compile the source? I wanted to make a few adjustments, but Cygwin is unfamiliar territory for me and I'm not sure how to turn my modified .cpp into an .exe

That's because they're skinned, and I'm making no attempt to figure out the bone matrices. Skeletally animated models are drawn as if all the bones were positioned at the origin, which is why they look screwed up.
