Dynasty Warriors 2 PS2 file help

[NoobGamer]

Hello my friends! I have the files to a 600 mb ps2 game I grabbed from my ps2 disc but when I open them in a hex editor they are layed out in a very strange way. I am not sure how to go about this and need some help. I will upload some files for viewing if anybody wishes to look. I will also include some screenshots. The filenames are visible but at the very end of the file and they don't seem to end with a null value right after the end of the file. I also can't seem to find the magic ID. I am hoping to at least be able to unpack the files so the dynasty warriors community can mod it. Thank you for your time. The BNS file is the main file.

I just added the elf file. I had looked at existing scripts for bns files but they didn't work for it. They used the elf file as well so that may be needed but not sure.
