4 months ago, critor released mySpire(http://www.cncalc.org/forum.php?mod=viewthread&tid=9441) which allowed modification of nspire CX/CM’s boot splash screen. Since the image itself is signed, there is no way to change the image except modify its position, size, etc.
However there is still a workaround. It’s possible to use third-party payload to display extra things on the screen. So here it is.
A little bit probe and some experiments, and, it is here.
Greeting from the first day of 2014!
It has been 27 years since the first graphing calculator – CASIO FX-7000G – was invented. Today, all new graphing calculators have color displays. Believe it or not, back to 1993, there is already a color display graphing calculator: CASIO CFX-9800G. The one I am going to review, it the CFX-9850GB Plus released in 2002.
Floating point calculations will produce a wrong result!
