Overwrites your Casio calculator off screen logo
with the content of a BMP image.

Calculators supported:
- fx-7400Gii (Graph 25+Pro)
- fx-9750Gii (Graph 35+USB)
- fx-9860G/fx-9860G SD  (Graph 85/85 SD, fx-9860G Slim, fx-9860G AU)
- fx-9860Gii/fx-9860Gii SD  (Graph 75/95, fx-9860G AU+)

You need a raw OS backup image.
For example, it can be obtainted from a real calculator with the fxRemote dumping/flashing tool:

The BMP has to be in 128 x 64 x 1bit (can be called monochrome BMP or 2-colors indexed BMP).
The Paint tool provided with Windows can save files using this format.

Usage on the command line: 
g2_offbmp_injector <source_rom> <bmp_file> <dest_rom>

Then you can flash the modified OS image with fxRemote for example.


Have fun!
