Mighty Flip Champs! help (.anb, .anm, .tex)

[TeridaxXD001]

I have a dump of Mighty Flip Champs! DX for PSP. It seems sprites are stored in the .anb format. However, I can't get any .anb tools to work on them. It also contain's .tex files, and the same goes for them. What do I do?

Here's a .anb file.

Here's a .tex file.

UPDATE: I now have the original DSiWare version. The files in this version have the .anm extension instead of .anb. I still can't extract them with existing tools, however.

Here is the .anm equivalent of the first file.
