Doom iPhone: base.iPack

[GreebCables]

Hi guys,

I'm currently working on editing the iPhone source port of Doom, however many of the images (main menu etc) seem to be compressed in the base.iPack file.

Does anyone know how to uncompress or edit the contents of this file?

Many thanks.

There is code to unpack iPack directly in doom classic source code, obviously :) So you can easily write unpacker by yourself. We lost our version of unpacker, but you can use our packer: https://github.com/TermiT/mkpack

Thanks :) I see there's code to access the resources in the iPack in the code but I hadn't a clue how to put one together for my own images. I wonder what program Carmack initially used to put it together.

One question about your program, though, I can't seem to get it to run... I keep getting "./mkpak: cannot execute binary file" error when I try to run it, am I doing something wrong? My linux skills are not the finest lol.

You need to rebuild the binary

Hmm I tried running Make and it gave me

You need to find out how to install a development environment on your distro... pkg-config missing is not a good sign :P

also it seems you also need to get libsndfile and opengl (development/header files).

[GreebCables]

Thanks I got it working by installing libsndfile and qualifying some of the namespaces in the .cpp file.

Do the textures have to be in PVR format?

id released source code for updated version of doom classic (2.1), it also contains ipack utility.

Can someone compile the ipack tool?

[GreebCables]

You should be able to load it into xcode and compile it as a mac console app
