Why are there no action packed programs for fx7700 and cfx-9800?
Since Casio never implemented “Getkey” command it is impossible to feed live data while the program is running, making games such as Tetris or Space Invaders impossible to make. However on the new cfx-9850G and cfx-9950G the “Getkey” command is implemented, so you can expect some action packed game on cfx-9850G model.
