ROM Hack Extracting models and textures from 3DS games

[I pwned U!]

Someone else has apparently had some luck with extracting some 2D Dream Team graphics!

I am still trying to figure out how to extract the ExeFS without any errors. I have not had any time to try to figure it out recently because I have been very busy. I have even been accepted into Nintendo's Wii U developers program!

Man, that's really cool, but at the same time...what the hell?!?

The sprites are pieced together by GAME CODE?!

I....why? Isn't that extremely inefficient?

It was probably extracted incorrectly at first. Didn't line the image up correctly when he pulled it out.

Models from Pokemon XY apparently made it to garrys mod.

Can't wait to see Diance holding an AK47 Xddd

All Mario & Luigi games are animated with pieces instead of multiple sprites. Image extractor is figured out, now the map file is needed to piece them together.

It's not inefficient, it saves space.

Huh. So, for example, if an arm was used on two different sprites, it would only be on the sprite sheet once, correct?

It just takes pieces from one file and puts them together. Right and left facing arms aren't needed because the image can just be flipped.

Processes like this have been used for over 30 years in gaming Mirroring tiles was very efficient for saving space; it's less needed today, but still not a bad form of optimization.

I ripped a Mega Aerodactyl and ported it to JanusVR, haha

Also I wrote a wrapper in C# for the go scripts. It not only makes your life marginally easier, but my program is meant to mass dump a directory of models..

File types it supports:
- PC
- PF
- PT
- MM
- BM

I limited to that just so people dont break things.

I found the map models :0
I dont see the texture data in these files though..

What game be this?

 

[NCDyson]

I'd be willing to bet it's Pokemon X/y

Yea, Pokemon X.. models are in a/0/4/1
first u32 = magic (GR)
second u32 = pointer to some random block of numbers (tile properties perhaps?)
third u32 = pointer to BCH

I'll probably add support in my program for the hell of it

Gericom Any news on your fancy tool?

Does anyone know how to turn it into an .exe?

Well that sucks.

Well that sucks.

You can still run it if you install Python.
