Looking for help with files extraction for Code Lyoko PS2 game.

[Madiator2011]

Hey guys I plan to upscale textures for this game but I have issues with extracting/repacking game file Code Lyoko: Quest for Infinity PS2 version.
I'm sure that video files are stored in PSS format and graphic for GUI are in .BKG .

I'm adding as attachment sample files and game directory structure.

The .BKG file is an RGB24 raw image - the width is at offset 0x0c, and the height at 0x0e - the .bkg file attached is 512 x 384

The image data starts at offset 0x12 - I'm not sure what the other values in the header signify.

Any ideas if that would be possible to extract and repack again?
I'm not good at reverse engineering

Do any program support that type of images?

It's certainly possible. As long as you keep the same size image, you should be able to use whatever package can create RGB24 images, and just replace the raw image data in the file.

The thing is that I want to upscale textures
