Trying to Export the Unity Animation Format to the BrawlBox;BrawlCrate Animation Format

[P0W3]

Using Blender (v2.93.5), I imported the Unity FBX format (the 3DS Pokemon format) into Blender. Here is the skeletal character. When I pushed the "play" button, you will see that the skeletal character does have the animation file.

But, I have to export the skeletal animation format that I saw in Blender to the BrawlBox;BrawlCrate animation format. And, I did export that skeletal animation format to the Blender FBX format.

I put the Blender FBX format in BrawlCrate (v0.37), and it did not work.

You do not see the Blender FBX format. Because, I did put the Blender FBX format in BrawlCrate.

When I looked at the Export format section, it appeared that none of these formats are supported to converting that skeletal Unity FBX format into the BrawlBox;BrawlCrate animation format.

Even when I did export that skeletal Unity FBX format into the BrawlBox;BrawlCrate animation format, it is still no use.

When I did do some research, none of those addons are there for Blender to convert the skeletal Unity FBX format into the BrawlBox;BrawlCrate animation format.
