ROM Hack Recreate a CTPK File - Have some problems

[xXDungeon_CrawlerXx]

Hey Guys,

I want to edit a CTPK File (a Texture) but I've a problem now.
I found out that the original File uses RGBA4-Format but no CTPK-Tool is able to create a file in this format.
Now I know that I can create a BCLIM in this format and copy the CTPK-Header (0x00 - 0x7F) to this bclim file + removing the last few bytes of the bclim file.
Now I ran into a other problem:
The CTPK-Files of this rom are a bit different. Do you find the difference between the original File and the recreated file?

Spoiler: SCREENSHOT

exactly!
Every single bit of the original file (excluding the header) is -1 of the recreated file.

So my question:
Someone who can help me by creating a tool which ADD "1" of every single bit of a file?

I tried to use the recreated file but the game crashes when It tries to load it.

Same thing happens to me with Battleminer. What game is this?

It's the Nisekoi Manga.
Need to change some images/textures for custom Mangas.

Anyways, I got it!
I wrote my own tool to add 0x11 to every byte of the file.
It isn't the best solution but it works:

Spoiler: Sourcecode

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
    unsigned char onebyte;
    FILE * OldImage;
    FILE * NewImage;
    char charfilename[80];
    char charfilename2[80];
    int filelength;
    printf( "Enter the filename\n");
    gets(charfilename);
    printf( "Enter the new Filename\n");
    gets(charfilename2);
    if (strcmp(charfilename2,charfilename) == 0)
    {
        return 1;
    }
    OldImage = fopen(charfilename,"rb");
    fseek (OldImage,0,SEEK_END);
    filelength = ftell(OldImage);
    fseek (OldImage,0,SEEK_SET);
    NewImage = fopen(charfilename2,"wb+");
    while(filelength > ftell(NewImage))
    {
        fread (&onebyte,1,1,OldImage);
        onebyte = onebyte+0x11;
        fwrite (&onebyte,1,1,NewImage);
    }
    printf( "Done.\n");
   return 0;
}

Have you checked what happens if a byte is F0 or larger before adding? Does it roll around to 00? Or does that never occur?

In the recreated file (RGBA4 Format) the highest byte is "EE".
So F0 never appears, no need to check it ;D

Tested it: FF will change to 10 but all my recreated files doesn't contain bytes Higher than EE
