The OS wouldn't work, because it is designed for different hardware. You would probably get stuck in a reboot loop. If you removed the boot2 like you were supposed to, you should still be able to delete the OS using the reset button or the boot2 menu.

Metroid Prime for $6. Then my parents took away and subsequently lost the game, so I learned how to run Wii/GC games off an SD card.

Did you look at the readme for nLaunch? You have to rename the OS file to phoenix.tns and send it as a document to the calculator, and then send a different, glitched OS file that starts the installation process.

To remove the fisheye effect, you will want to calculate the distance of the walls not from the camera position, but from a line that goes through the camera position and is perpendicular to the view direction.

You should avoid using short variables because it makes the code harder for others to understand. If you still wish to use them because they are easier to type, it would be great if you made a key with the meanings.

Does the dock have USB and charging contacts?
These are not printed, and as he said in a previous post, the dock circuit board (at least the correct dimensions) still remain to do.
According to the TI-Nspire Charging bays, it is possible to charge it via the dock.
Let me rephrase that. Does the dock connector on the calculator have contacts for USB and power? Also, did you design that in Blender?

The reason your code might be going so slow is that you are calling the cosine function 64 (!) times per screen column (twice in line 176, and twice in the for loop starting at either line 177 or 186, times the 31 times the loop runs), or 20480 times per frame. Since viewingangle only changes once per frame, you can compute cos(viewingangle) once for the frame and store it in a variable. j does change throughout the frame, but cos(j) is only called for j from -30 to 30 so you can make a lookup table for those values. You might want to take a look at this tutorial. The rendering is completely vector based, eliminating the need for trig functions during performance critical loops. One last thing, in the future, you should put threads asking for programming help in the C language subforum.

@Levak ; not really a good idea? because I am a poor college student who really needs his calculator to do laplace and inverse laplace for exams, which cannot be done without this OS. I will try it anyway before having to pay an extra $80+ just to run this simple program. Hopefully it will not mess up the calculator before I return it if this does not work
By not really a good idea, he means it won't work at all. The CX and non-CX have different hardware, which means different memory addresses and such so the OSes are incompatible. But do go ahead and try nLaunch, and make sure to install the CAS non-CX OS. Here's a link to the right OS: http://tiplanet.org/forum/archives_voir.php?id=3720

Oh wait I forgot about that Apple restriction junk. Programming languages are against the rules, so since it's possible to use TI-BASIC on the Nspire Student software emulator it would prevent it from being released on the AppStore. However now that this is brought up, I thought emulators were banned from the AppStore althogether? 
Apple bans video game emulators because they don't want to deal with legal issues from console manufacturers. They do allow programming apps now, but everything has to be self contained.

Which generation is this? Clickpad, Touchpad, or CX? If you have a Clickpad or Touchpad, you can just install the CAS version of the operating system on your current calculator using nLaunch.

TBH, we should just move on to another, more modern architecture that has all of these features. Once you know how to structure a program in ASM for one architecture, writing it for a different architecture isn't that hard.

It might be that the batteries in both the calculator and the iPod Touch have a higher rate of self-discharge.

Which program specifically?
