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.
This screen was manufactured much earlier than the last screen, so early that it is an STN screen instead of an FSTN one. But I would say, still a good one, I just like screens.
Just a nice-looking 320×240 controller-less LCD. Got it at a very low price ($0.7 each). I am always thinking about making something around it, but it just doesn't happen.

A great thanks to all ndless/nSDL developers! I got this in less than 5 hours thanks to these libraries available.
I deleted all the musics or voices (as there is no way to play them back). Now the main program is 384KB in size while the resources are 21.9MB total. Monochrome models will run the game, but that would take up all the available space. I am thinking about further compress it. Save/Load not working currently.
