Homebrew [Rom and save] How can I read the Mega Man Zero Collection .sav file?

[ModelZ]

I’ve imported the .sav file to HxD, yet the hexadecimals alone doesn’t say much. Does the rom help translate the file? If so, how can I use it to read a specific .sav file?

All in all, I want to read the file’s hidden result screen average counter for Zero 1 and 2.

I have the latest version of Desmume and HxD.
