fx-9860G f-key files

An fx-9860G f-key file is a data file containing images for function keys (abbreviated f-keys) for internationalization, for fx-9860G and derivatives. It can be identified using the G1N extension, and uses the CASIO container with a subtype to be determined; see By CASIO container subtype for more information.

Note

The calculator skips directly passed the header and only checks the extension of the file, and no example of a legitimate G1N file has been found yet.
