Iron man 2 Xbox360 pkg files finally extracted!

[zabana]

Hi all!!!

I´m trying to extract models (textures are not necesary but not a bad goal to reach) in pkg files.

I was looking over google, and forums trying to find some info, but right now I only know two games which use these kind of packages (golden axe and Iron Man2, i can figure Iron man 1 too...)

After reading a lot of forums,post and guides I was studying and comparing files so I reach to know where the directory name is, something that seems to be the header, where to read how many models/parts are inside and where it points (also usually begins at same place in every file).

But I crash to a wall, I can not determine any other pattern to follow, so that´s the reason I´m begging for help. Of course if someone have the clue in how to do the all thing would be a lot of helpfull to receive scripts or whatever, if not with right pointing maybe I can resolve the puzzle by myself.

Thanks in advance to everyone who at least read my requesting and also I want to apologize about my english

I was playing with hex editor, files and such...

Finally I was able to discover the pkg structure and was able too of extracting and decompress all strings files (in 5 languages). Now I need to face another problem, and is the model structures and learn how to get vertex to begin...

This the basic structure of strings files, but can be applies to the other ones, if anyone could help in my next step would be great!!!

I´ll add here excel table with what I think is the pkg format (not found vertexes yet).

In iron man pkg files are closed as this ones but some data are zlib compressed.

[zabana]

First goal reached!

I´m able to draw vertexes in both Iron Man 2 and Golden Axe-Beast rider (it took me 8 days from zero, my first time doing it )

Now need to find faces

[zabana]

Finally done extractor in C++. Now taking a rest to decide if do the model with textures or not

Looks awsome. Well done.

I think you should do the textures as well you know the models will look that much cooler with the proper textures than without them..

Also i see you created an extractor in C++, would you be willing to release the extractor to the public, or would you rather wait untill you have the textures fixed too?

Keep up the good work !

Nobby

[zabana]

Thanks!

I´m not going to release it yet. I want to decide first about textures but like you said models with textures are cooler so I need to learn a few things yet

[FEATHER]

Very nice zabana, i'm crossing my fingers for this release

[Tosyk]

Great news zabana, i'll stay tuned!

[logansan25]

Very cool!

[XLAX]

any news of release yet?

[Rimbros]

Sabana can you share the warmachine model with texture, i cant found one of this.thanks.

[Nobby]

As its been a couple of months since you last posted so id presume you have either stopped production of this or cannot figure out the texture grabbing. So could you please release the extractor you have in its current condition. textures altho nice are not really important. iron man is just red and yellow and war machine is just black and grey so we can do standard materials for them instead of textures. But we would really love to be able to get the models.
So PLEASE release the extractor so we can have a play.

Cheers in advance..

Nobby
