Raw "Save Type" data

[mariomadproductions]

Is the Save Type (as printed in the GM9 cart .txt file) just determined from the save chip ID (also printed in the .txt file), or is it based on additional values. If so, might it be a good idea to print those values in the .txt file too?

GBATEK seems to suggest that the "RDSR" response is also relevant: https://problemkaputt.de/gbatek-ds-cartridge-backup.htm
