Lol DJ, scanlines are a good idea indeed. Maybe you could do actual vertical interlacing too. That'd make it twice as fast to draw to the screen and you wouldn't lose much quality if the frame rate is high enough. ;)
The issue with vertical interlacing is that this uses 160x240 mode, so the vertical lines would be twice wider, thus, more noticeable.

Also, since the LCD is placed vertically, the extreme flicker that would result from drawing every two line would cause eye cancer.

For those who don't have the real calc, this is how the 84+CSE LCD look like in 160x240 mode:



See what happens in the right screenshot with vertical scanlines added.

I made a few small changes to improve the accuracy of the engine. It is mainly evident when at angles of 90deg intervals as shown below. At 45deg it is still pretty average, but at least its a little better overall.



Also i like the idea of scanline interlacing, its something that i have been thinking about implementing. Such a trick should greatly improve speed, just not sure about image quality.

Spoiler For Flickering Image:

If you think that could cause seizures, you should put it in a spoiler so people don't get seizures from the screenshot  ;)

Nah, I doubt this would be enough to cause seizures. However, on a real calculator, the flickering would be so incredibly annoying and eventually cause some eye strain or something.

calc84 spoke about porting his engine to the CSE as well (well more like added to his todo list). I jokingly made a deal that he can do fzero and i can do mariokart! Though I doubt anything more than a demo will come of this, I would like people to try it (when its in a more usable form).

Here is another screenie without the free rainbow road:



Also as Runer noted, the angles/elevation/scale/distances etc are all out of whack as this is a proof of concept. This can be adjusted and will need to be if its going to be any use to anyone.
