Extract Raw Image

  1. Extract the ps2data/image/ff12/myoshiok/in/bin_menu/item_gra00.as7 file via the VBF Browser.

  2. Create a directory and put the ff12-as7.exe file into it.

  3. Navigate into that directory.

  4. Press Ctrl + L to focus the address bar of the file explorer.

  5. Press Backspace, type cmd and then press Enter to open the Command Prompt.

  6. Type the following code into the Command Prompt:

ff12-as7.exe -u item_gra00.as7 item_gra00.raw

  1. Press Enter to convert the .as7 to a .raw file.

Extract Color Look Up Table (CLUT)

The item_clut.bin file contains the color of all 7 .raw images in order, each one being 1024 (0x0400) bytes.

The color data of item_gra00.raw is at 0x0000 to 0x0400, the color data of item_gra01.raw is at 0x0400 to 0x0800, and so on.

The start offset is File Number * 0x0400, and the end offset is Start Offset + 0x0400.

To load a raw image with its associated clut, you will first need to extract its clut from the item_clut.bin to its own file (.cl2). To do that:

  1. Extract the the ps2data/image/ff12/myoshiok/in/bin_menu/item_clut.bin file via the VBF Browser.

  2. Download item_gra00.cl2 from the Files section (rename file number if necessary).

  3. Open item_clut.bin and item_gra00.cl2 with a hex editor.

  4. Copy the bytes from 0x0000 to 0x0400 in item_clut.bin (start and end offset depends on file number).

  5. Paste the bytes into item_gra00.cl2, starting at offset 0x40, therefore replacing all 0xFF bytes.

Merge Raw Image & Clut

Now that you have both the raw image and the clut, you can merge them. To do that:

  1. Open item_gra00.raw with an image editor.

  2. Once the image size is requested, provide it based on the calculation from here (e.g. 64x6144).

  3. Save it by setting the file name to item_gra00 and the extension to .png.

  4. Open item_gra00.png with Optpix Image Studio.

  5. Select the color palette right from the image. If its not there, press Ctrl + L.

  6. Right-click on the color palette, select load palette and then open item_gra00.cl2.

  7. Select File -> Save As from the top navigation bar (or use Ctrl + Shift + S).

  8. Set the file name to item_gra00 and the extension to .png.

  9. Click on the Save button (changing file saving options isn't necessary).

Notes

When assembling a .cl2 file, make sure that the file size stays the same. Its always 0x0440 bytes. 0x40 for the header and 0x0400 for the color data.
