FF7 Tools / Re: PC - FF7 LGP Loader

« on: 2011-08-19 17:52:02 »

Hm as far as i know does Alis LGP tool extract the files, or recreate a archiv.

But if i just want to read data from the archiv i dont need to extract all the file just holding the needed files in the memory is enougth.
Therefor i wrote this little dll to get access to all the files in the lgp without extracting them on hd.

You can open the lgp archive and load the files in the archiv direct in to the memory to work with them.

I need this for a little tool, and with a dll it is just faster to implement if i need it again.

FF7 Tools / [FF7] LGP Loader (2011-08-19)

« on: 2011-08-19 16:31:14 »

Hiho,

Sorry my English is not so good but i try my best an hope you guys understand me ^^

Yesterday i had an idea for a tool and for this idea i have to load the ff7 lgp files in to the memory.
So i wrote a little dll to do the job.

It has just a few functions to load the lgp in to the memory but if some one want to test it i Uploaded it here gromtars_lgp_loader
I wrote it in PB (PureBasic) so the test source file is in pb but it should work in each language that can load dll's

Now i looks good 


But the face groups are messed up


The heads are working but why does the faces look so broken  any ideas ?

Scripting and Reverse Engineering / VerticesStartIndex to each vertex index

« on: 2010-09-06 04:41:51 »

Hiho,

again i have some litle question 

The thing is my english is not the best so im not sure if i understood the Wiki correct.

Im currently working on the p file and need to get the vertices.
The wiki says this "you have to add group.VerticesStartIndex to each vertex index".
does this means i have to add the group.VerticesStartIndex to each index i get from the polygon.VertexIndex?

Somthing like this

Code: [Select]

v1.x = vertices[groups[x].VerticesStartIndex + polygons[y].vi_1].x;



EDIT:
------------------------------------------------
Ok now its "half" working 
Her face is just a hole

General Discussion / just one stupid litle question

« on: 2010-09-01 04:00:48 »

Hiho,

3 weeks ago i finished my last PB project (loli-browser) and got a litle bored i didnt knew what to do next.
Then i thought i try out PB + Irrlicht and do somthing but the PB Irrlicht wrapper is to old so i thought "ok lets try c++"
and finaly i tripped over Qhimms wiki and there i got an idea i wanted to make a litle model viewer
but as engine i wanted to use Irrlicht it should load the models on a bsp map so i could walk over the maps with it.
So i could learn more about C++, Irrlich and the FF7 files in one little project.

But i just read the harsh answers Senti became for his Idee and wen i think about it my model viewer would
do the same, it would load the models out off the lgp to Irrlicht and on top onto a map.

So i just got a little lost, should i drop this idea and do somthing other?
But i just dont know what (any idea's?  )

-------------------------
Sorry for my bad english.

Hm,

the idee is nice but i think, if your going to do this dont use the Unreal def kit.
What i mean is, Epic Games is a ("konkurrent" sorry dont know the correct english word) rival to Square Enix so it wont be a good idee to use this 

Not going to agree with the whole "FF7 must be installed" deal with you on this. Considering it will be completely made from scratch, I think all the rights other than the ideas for the game belong to you, and unless it is a moral thing for you, you should feel free to distribute it freely. Just a thought.

I think it is a good Idee to check if the orginal is installed or a ff7 psx cd is in the cd drive, even if the sources are not from Square Enix/Eidos but the rights for the name "Final Fantasy7 etc." lies with them.
But if you make sure Square Enix/Eidos will have their share with this, you minimize the risk to get sued.

for (int i = 0; i < 8 && inputPos < ll_obj->curr->filesize; i++)

This done it  now it works fine, thanks.

And thanks at all for the usefull tipps

Morning  ,

Ok now it works fine only a litte thing is off 

Code: [Select]

    int lgp_tools::decodeLZS(int fileID)
    {
        ll_obj->SelectElement(fileID);

        unsigned char *data = ll_obj->curr->memPtr;
        unsigned char controlByte  = NULL;
        unsigned int input_offset = 4;
        unsigned int output_offset = NULL;


        unsigned char* output_buffer = (unsigned char*) malloc(ll_obj->curr->filesize * 9);

        while (input_offset < ll_obj->curr->filesize)
        {
            controlByte = data[input_offset++];

            for (int i = 0; i < 8;i++)
            {
                if((controlByte >> i) & 1)
                {
                    output_buffer[output_offset++] = data[input_offset++];
                }
                else
                {
                    unsigned char ref1 = data[input_offset++];
                    unsigned char ref2 = data[input_offset++];

                    unsigned short RefLength = (ref2 & 0xF) + 3;
                    unsigned short ref_offset = ref1 + ((ref2 & 0xF0) << 4);

                    int real_offset = output_offset - ((output_offset - 18 - ref_offset) & 0xFFF);

                    for(int x = 0; x < RefLength; x++)
                    {
                        if (real_offset  + x < 0)
                        {
                             output_buffer[output_offset++] = 0;
                        }
                        else
                        {
                             output_buffer[output_offset++] = output_buffer[real_offset + x];
                        }
                    }
                }
            }
        }

        ll_obj->curr->filesize = output_offset;
        delete(ll_obj->curr->memPtr);
        ll_obj->curr->memPtr = (unsigned char*)realloc(output_buffer, output_offset);
    }
The decoded Data is the same as the data i got with highwind only that i get 20-30 byte to manny after the "FINAL FANTASY7" tag 
It seems it goes over the last controlbyte

Thanks you two, now it seems to work.
The problem was that i got the first controlbyte wrong 
The file header inside the lgp is 24Bytes and i used 20 + 4 for the lzs so i had it 4 bytes to short

Hiho,

sorry for my bad english but i try my best and hope you guys understand me

I have a little problem with the LZS compression.
I am currently learning c++ (2 days), then i found the QhimmWiki and it seemed interesting so i put some code together to load the lgp's in the memory and dump files out of it to the HD.
So far it worked good but now i want to unpack the lzs files but it seems i am to stupid 

For the start i wanted to walk down all the controllbytes and lenghtbyte of the refference to get the total size of the decodet data but i get the wrong input pos and dont know why.

Code: [Select]

    int lgp_tools::decodeLZS(int fileID)
    {
        ll_obj->SelectElement(fileID);

        char *data = ll_obj->curr->memPtr;

        int inputPos = 4;
        char controlByte;
        int wSize;

        while(inputPos <= ll_obj->curr->filesize)
        {
            controlByte = data[inputPos];
            inputPos = inputPos + 1;

            for (int i = 0; i <= 7;i++)
            {
                if ((controlByte >> i) & 1)
                {
                    inputPos = inputPos + 1;
                    wSize = wSize + 1;
                }
                else
                {
                    int len = (data[inputPos + 1] & 0xF) + 3;

                    wSize = wSize + len;
                    inputPos = inputPos + 2;
                }
            }

        }

        cout <<  wSize <<"\n";
    }

Wen i dump the "ll_obj->curr->memPtr" to hd with this

Code: [Select]

    void lgp_tools::dumpFile(string path, int fileID)
    {
        ll_obj->SelectElement(fileID);
        ofstream outputFile (path.c_str(), ios::out | ios::binary);
        outputFile.write((char *) ll_obj->curr->memPtr, ll_obj->curr->filesize);
        outputFile.close();
    }
the file has the same content and file size as the file i extracted with highwind. So the input data cant be wrong.

Does some one see the error? I dont get it  (like i said it seems i am to stupid )
