fx-9860G add-ins

An fx-9860G add-in is a native application that can run on fx-9860G and derivatives. It can be identified using the G1A extension, and uses the CASIO container with subtype USBPower\xF3\0\x10\0\x10\0; see By CASIO container subtype for more information.

Past the CASIO container header, such files start with a 480-bytes long header formatted the following way:

Offset	Size	Field name	Description	Values
0 (0x00)	8 B	Internal Name	Internal name starting with @, used for referencing the add-in from another add-in on the calculator.	Zero-padded string, e.g. @APP\0\0\0\0
8 (0x08)	4 B	E-Strip Count		Big endian 32-bit integer.
12 (0x0C)	4 B	Reserved		Should be set to \0.
16 (0x10)	12 B	Add-In Version	Version to be displayed under SYSTEM > VERSION.	NUL-padded MM.mm.dddd, e.g. 01.23.4567\0\0.
