You are right. That's definitely a binary file.

However, the problem is now understand how data is stored in the file.

In the beginning there is 01 00 02 00, then more 'random' bytes. Does this suggest you anything?

I'd read a limited memory area with a known content and compare it with the file, in order to understand if memory is simply saved as is, without any formatting. I think probably so, since your file is exactly 512KB long, which is probably you sram dimension.
