If the menus and prompts are in French or English, cela ne fait aucune différence pour moi. OK, so I don't write it very well but I can still read it!

I'm afraid the answer is no. I've looked at the download area on the Casio website, and there is only one firmware available for the "fx-CG50 series". The site says:
"applies to the following models:
fx-CG50
GRAPH90+E
fx-CG50 AU"
That would mean that the user cannot choose the firmware.

EDIT : Read the question asked by parrotgeek1, and the answer given by critor here.

I would like to be sure however, because I could be interested in this calculator, but I would prefer the black case of the fx-CG50. On the Graph 90+E, the orange labels on the white background seem to have poor contrast.
