That IS going a bit far.

lol!
When I was a total noob, I used gotos before I learned about while and repeat.

I have two questions about the engine:
A. How does the engine react to non-square textures?
B. Is there a way to disable sprite drawing? (Having nothing in the sprite struct gives an error)

Or better.

Agreed. Open spurce software is less buggy because more people have the opportunity to catch it and fix it.

I just had another idea-256 level grayscale!

Still, actual dithering wouldn't be too hard to implement.

lol that would be epic

I think that dithering was from the screenshot program-it is dithered in the border of the emulator.

Oh, I see. Its too bad the smallest cursor size is 32x32. Also, have we decided what size of display we're going to use? 480 x 320 would be nice.

I took a closer look at the LPC313x, and it doesn't appear to include the PrimeCell PL110. Instead, it seems to have its own LCD controller that requires manual output (unless you set up a DMA to do so). I'm not sure what types of LCDs it supports. But otherwise, the LPC313x looks pretty good. It supports High Speed USB 2.0 OTG and SD/MMC, among other things. It is clockable up to 180MHz. And I just found a site that lists the price at $7. Seems like a pretty good deal 
Edit:
I found what may be even better: The LPC3230. It has the PrimeCell PL111 (which, in addition to the PL110 features, has hardware support for displaying a cursor on top of the frame), and a Vector Floating Point co-processor (perfect for your hardcore floating point math operations!). Of course, it also has the USB and SD/MMC support as well. It is clockable up to 208MHz. It's around the $10 range I believe.
That's great! However, is the LCD controller any better for this one?

For data structures, I think it should have more standard data type support, aka, instead of lists and matrices, have multidimensional arrays. It should also of course have things like strings and numbers, not sure whether it would be advantageous to have separate int types, etc, but I would guess not.
I don't think we should have different number types, rather, just a float that applies to all numbers, like in TI-basic Strings are fine, they could be used in say, a dictionary program. For variables, I think they should be done similar to C, where they are declared, and can have any name, and be any type (number, string, list, matrix, etc.) Control statements: If, Else Elseif, For, While, Break, Try (executes block of code, error code, if any, stored in a variable), Goto, and anything else useful. Operators: +-*/, negative sign, exponent carat, <>=, assignment, not, and, or, xor, not-variants. I/O: Getkey, Link(sends/recieves 1-byte codes on the link port), pixel-commands, line, circle, polygon, draw function, draw sprite, scroll screen, and so on and so forth.

Instead of using TI's linking libraries, why not use TILP's? Then, you can also get permission to distribute those with the installer.

I would rather have a regular SD slot than microSD, they're cheaper, and not all that big.
A backlight would be nice, provided there's variable brightness.
Micro USB is a no-brainer, we can then have the calc act like a USB mass storage device.
I voted for a 3.5mm link port, as the cables are more common, and we won't need an adapter to use headphones. A 3.5 male to 2.5 male should be included if we want to connect with TI calcs.
There shouldn't be a touchscreen, this is a calc after all.
This calc should be powered by AA batteries, they're cheaper and hold more power.
For built in charging, the user should select if they have rechargeable batteries or alkaline, and if they can be charged, the OS can let them be charged from the usb port.
