I have no idea if this is even possible, but maybe one of you guys has an idea.

I have the 1998 game FutureCop LAPD installed, and I'd like to rip models from it (probably impossible). Modern DirectX rippers or w/e don't work because it's too old, as far as I can tell.

The game data is ENTICINGLY suffixed ".bin" which made me think maybe I could open it with Stuffit Expander. No dice, though. Presumably it's not a CD image, and it doesn't come with a .cue file or whatever.

Any ideas? Is it possible I can rip stuff out of this game or will its secrets remain LOCKED AWAY FOREVER

I've done work like this before. It might be a compressed filesystem of some sort, or just a blob of assets accessed by index offsets.
It's definitely possible to extract the data, but it will probably take some work.

How big is this bin file? Are there any associated index files? Crack it open in a hex editor and poke around a little.
And when the moment is right, I'm gonna fly a kite.

It's about 9 megs. Here's the file for reference (it's from the free demo version so I don't think there's a copyright issue)

I don't think there's any associated files--the game installation is an EXE, the .bin file, and a folder called "missions" with some files that don't have any filetype suffix at all. I wouldn't mind cracking those open either

I'll definitely see what I can do with a hex editor, thanks!

.bin is one of those filetypes that while these days we associate it with CD images, really doesn't have a fixed format. Taking a peek at it, looks like the resources are just thrown into that file one after the other, I didn't see anything that would give a hint as to the contents.

.bin means binary, aka a file for non-text information

This is a 16-bit texture. 0x2400 is about this color (218100) if it looks familiar to you.

Ascii 'BM' shows up a lot so it's probably the start of a texture file. Width and height data will follow between this and the bitmap data. Could be big endian, could be little endian. Just takes experimenting.

Can't see any archive metadata, normally it would be at the start or at the end but it's 16-bit bitmaps all the way through, so it either has an external index or they compiled it down to file offsets or something.

These files are standard 16-bit bitmaps.
2015-07-15, 3:40 PM #9
The first 32 bits of the file are a count. Everything else in the file is a standard 16-bit bitmap file.

Can't say I think much of the images in this archive, but this program will extract them for you.

Code: 
#include <iostream>
#include <cassert>
#include <cstdint>
#include <vector>
#include <sstream>
#include <fstream>


int main(int argc, char **argv)
{
    assert(argc == 2);


    std::ifstream f(argv[1]);


    // Skip first 32-bit int (count?)
    uint32_t count = 0;
    f.read(reinterpret_cast<char*>(&count), sizeof(count));


    uint32_t curr = 0;
    while(f.good()) {
        std::stringstream fn;
        fn << "image" << curr << ".bmp";


        uint16_t ident;
        f.read(reinterpret_cast<char*>(&ident), sizeof(ident));


        uint32_t size;
        f.read(reinterpret_cast<char*>(&size), sizeof(size));


        std::vector<char> buf;
        uint32_t bufsz = size - sizeof(size) - sizeof(ident);
        buf.resize(bufsz);


        f.read(&buf[0], bufsz);


        if(f.good()) {
            std::ofstream of(fn.str());
            of.write(reinterpret_cast<char const *>(&ident), sizeof(ident));
            of.write(reinterpret_cast<char const *>(&size), sizeof(size));
            of.write(&buf[0], bufsz);
        }


        ++curr;
    }
    return 0;
}

Thank you for these computer codes, I will research how to deploy them

4-10 MB apiece. Here they are: https://dl.dropboxusercontent.com/u/3677532/secrets.zip

Probably more likely to contain actual game assets, I don't know why I didn't expect menu stuff in the first one :v
