The Gunstringer: .gr2 files

[JoshuqTheHusk]

Heya, currently trying to figure out how to open these renditions of .gr2 (Granny 3D) Files, I cannot open them in Granny Viewer as I get the error: CRC Check failed, File may be corrupted.

Is there any way to open this?

It's not a standard gr2 file. And may not be a RAD Games gr2 at all. 
It has none of the header information that standard gr2 files have. A quick look tells me it probably has a 3D mesh with it's skeleton followed by a bunch of animations.

Ok. I spent more time with the file and it does appear to be a RAD Games gr2.

It is missing the header stuff as I said before so I might be able to modify some scripts I have to read the 3D mesh stuff.
If you have any more examples those would help.

here's every model I found in the folder.

models.zip

Got the files.
If you have the root files, I believe the header information is stored in one of those.

I'll work on the smaller gr2 files and see if there is a pointer to the 3D model information.

Here's two versions of the .xpr files they are found in:

This is one is uncompressed after turning it into an XPR2 file:

And this one is the original file:
