Geez, that's a lot of files :)

Nice news! ;-)

Yeah compared to the Metroid: First Hunt, and that was just a demo.

using the nds model viewer, right now we cant view anything in this dump. why? every single file is LZ77 compressed. NOT the same as ZIP, nintendo likes doing things their own way. ;)
so, if someone could figure out their compression method, and integrate this into the model viewer, that would be sweet.

This is designed to decompress LZ77 pictures from pokemon games,
might work straight out or need to be slightly modified.

Totally good work man. Wanna share any details about why you couldn't do it when you did metroid and how you overcame those problems?

I'm amazed.
What is the size of the rom ?!

Uuh, I haven't played this game yet but \data\enemy\peach\? Is this Princess Peach? I've never thought of her as an enemy before. :)

You've never played Smash Bros. against somebody who can beat 3 teamed level 9 CPUs with Peach.

I wonder what the odds are that someone will find a way to export the models and maps to a popular first-person-shooter model format...?

I suddenly want to import a whole lot of quake 3 weapons as shell models for some reason.

What's the size of the dump?
#35252 - DiscoStew - Wed Feb 02, 2005 3:35 am
Why do many people want to know the size of the dump anyways? I feel it is kinda irrelevent ATM.
If anything, I'd like to know the format and size of the raw 3D models and animation schemes, a good average poly-count on in-game models, etc, just so I would know what I can work with when the time comes when we all can do some actual DS programming.
I'm starting to get the itch of trying (once again) to learn how to use Lightwave, just so that I can get a head start.

Get a feel for the system in general and such. Or maybe to know what kind of game sizes we expect to be dealing with. I mean, Super mario 64 DS is just as large as the Metroid Prime demo. And it's only a demo, not the full game.
It could be a number of things though; i don't feel like thinking up more.

Found this gba LZSS decompression program:

but it's in ARM assembly...
