The image is in 8 BPP (aka 256 color) format. My tool will extract/insert it, but the color palette for the image is missing so the colors will be off. There is a bit of data at the end of the file which may be a palette of some sort, but the length doesn't match what would be expected for a 256 color image. Example:
OBSOLETE IMAGE REMOVED
You probably already know the following, but I'll mention just in case.
My tool will extract this image to a TIM format (Playstation) and generate a generic color palette. You can then use a tool like TimViewer (available here)
to convert to BMP, or the TIM plugin for Photoshop (available here)
to open the TIM directly in a supported photo editor.
Edit the image and palette as you like in the photo editor, but my tool only re-inserts the image, so any palette changes would only be to make the image easier to edit. Once you're done, just save/convert back to 8-BPP TIM, and my tool will insert it.NANA (available here)
works well as a reference for my tool to determine 'start location' and 'width'. It scans images in various modes 'on the fly'. Just drag the file onto nana.exe. Use the < and > buttons to change image width, 1-6 to set the BPP mode, and left-right arrow keys to slide the image sideways. Nana's 'raw:byte' mode (6 on the keyboard) is 8-BPP.HERE
is my tool. Included is the TIMproject file (just a renamed txt) which has the settings for the file you posted. It's a work in progress and may have some bugs. Any feedback would be appreciated.

I just looked at the image data in a hex editor. While it's technically encoded as 8bpp, it only uses 16 colors (all pixels are in the 00-0F range). The 48 bytes of non-image data at the end of the DAT is indeed a 16 color palette (16 colors x 3 bytes per color = 48 bytes total).
Each entry is standard, but their order is scrambled. In other words, black in the image data is 00, but that is the third entry in the palette (01 01 01). Normally 00 would refer to the first palette entry. Still, you should be able to edit these palettes if needed in your translation.
This image shows the palette data in HxD set to 3 wide rows. Red labels show the expected order. Also, here's 8bpp BMP copy of the image from the DAT file with the 16 colors of the palette edited to match your earlier screenshots. The image data is completely unchanged.
