I think i have these .fff files figured out.
We have been looking for headers all this time but I just realized that these files use footers instead.
At the bottom of each file is an index of what is inside the file, I realized this when looking through arc_000BD2DC_unpacked.fff (which im now fairly sure literally contains the raw code for the file parser, there is a massive block of code which looks like its related to file structures) there was a script somewhere in there that mentioned an endpoint, so I went to check and sure enough these fff files have an index at the very bottom and probably some file type information too.
The thing that is interesting to me is the [ IS-NITRO-DEBUGGER ] line at the top of the text block.
I searched it up and it seems like IS NITRO is a nds debugging emulator, Its definitely not there from the person who dumped the rom because the version is 2006.6.7 making it two years older than the Japanese release of fossil fighters in 2008, the US release was made in 2009 so if we go by US release date then it would be 3 years older.
This looks like it might either be a log file that they didn't remove, or proof that this game has a compatibility library for is nitro built in.
I'm seeing paths to .vtx files and .mdl so its possible whatever this tool is has access to dump the actual raw files in a windows-readable format
