Has anyone figured out the .cno format?

No, I'm not making a general purpose converter. I'm specifically trying to export your models into obj.

Here's what I found so far.

The file consists of chunks, each chunk has:
4 Byte > chunk-name or chunk-type
4 Byte > chunk-size (little endian)
chunk-size Bytes > chunk data

We have chunk types like:
NCIF - unknown
NCTL - texture file names
NCOB - geometry data
NOF0 - unknown
NFN0 - file name
NEND - end chunk

Number values in chunks seem to be in big endian. I'm working on NCOB currently. It has some unknown data and then the vertex data. The last 576 bytes of this chunk in cube file is vertex data. There are 24 vertices. Each vertex has 576/24=24 bytes. Those 24 bytes are 6 Float values, first 3 are x,y,z coordinates and next 3 are normal x,y,z I think.

I'll go to sleep soon. Are there any other files with the same name? I suspect polygon indices may not be in these. The unknown part in NCOB might be indices and uvs but they don't make sense.
