These programs are for the TI-83+ and TI-84+ calculators, including the 83+ SE and 84+ SE. They are mostly not compatible with the color-screen 84+ CSE or CE variants, but some BASIC programs can be run on all of them.

This is an incredible Sim City program, with real 8x8 sprites, a huge board to build on, cool road sprites, autosave of cities and total elimination of memory errors found in other Sim City programs. Also includes the ability to share cities between calculators, and cool real-time movement of people in and out of your city. Create 20 different types of buildings, environments, and transportation for the inhabitants of your city. Get people to move into every house and building and win; lose all your money and start the game over (you can reuse maps). This update of Sim City 2003 eliminates the wait for the city to render, adds a more intelligent simulation mode, and provides a graph of your city's monetary progress. Doors CS v4.0 optimized.

AsmOS is a bare-bones operating system for the TI-73, TI-83+, TI-83+ SE, TI-84+, and TI-84+ SE. It is a great starting point to develop an OS from. AsmOS will initialize hardware, boot up, and enter an infinite loop - it's your job to replace this loop with an awesome OS. It comes with a great build system that uses Spasm and Build8xu on Windows, in addition to a custom build tool.

A classic arcade game that has been reproduced many times on the calculator. Everyone i have talked to have said things about using Eulers number, whatever that is. I couldn't seem to figure out what it was so i came up with my own way to create snake using lists to store the places you've been. there is an easy, medium, and hard mode but they don't change the speed. instead they change how long you grow every time you eat a pixel.

Invalid Tangram can best be described as a cross between Space Invaders and Tetris. Build block combos to gain powerups, then blast the enemies into oblivion while avoiding destruction. Instead of health, you have time: powerups add to your time, but enemy shots can remove it. Run out of time and the game ends. Invalid Tangram DE is based on the PC game by Josh Szepietowski and is available for both Doors CS 6.0 and Ion. Now with source and several user-suggested improvements, plus Nspire support.

This is the second public release of the Doors CS shell as a Flash Application. Taking up a mere single page of archive/ROM space, this program is a complete shell and GUI for TI-83+/TI-84+ graphing calculators. It also contains a complete shell for the TI-83, Doors CS v5.1. Embedded but not yet activated in this version are such amazing features as a full GUI API. Doors CS can recognize and run nearly every type of TI-83/+/SE/84+/SE file available, including Ion and Doors CS ASM programs, TI-OS BASIC and ASM programs, and many others. The interface can be navigated with a mouse-like cursor, and is fully expandable with small modules called Shell Expansions. Manual included. Bugs fixed in this edition include: BASIC running bug, folder paste bug, battery meter bug, memory meter bug, scroll bug, and more.

This program computes the Jury's Stability Criterion table given the polynomial characteristic equation of a digital control system. It both determines whether the system is stable (in other words, if the first term of every odd row is positive) and displays the criterion table used to determine the stability of the system. The basis of the algorithm for this program was found in "Advanced Modern Control System Theory and Design" by Stanley M. Shinners, John Wiley & Sons, 1998. It was originally published in several papers including "A simplified stability criterion for linear discrete systems" (Proc IRE 50, 1493) in 1962.

xLIB xLIB Revolution, an hybrid-TI-BASIC Dance Dance Revolution clone with no music but featuring animated background images and a custom level editor. It was released in October 2005.
Super Mario Smash Dance is another hybrid-TI-BASIC DDR clone with no music featuring Super Mario Bros 3 monochrome sprites and a game mode where Mario power-ups and a classic mode with high speed per hybrid TI-BASIC standards.
Both games require OS 2.43 or lower and xLIB APP, which won't run on MathPrint OSes, and the last time the XXR game was tested with Celtic III and DCS7 it had major display issues.

Very old Metroid fan game for 15 MHz TI-z80 monochrome models. Two versions are included: Evolution and The Last Chozo Expansion Set. The latter includes extra power-ups, new areas and an extra boss fight. Written in TI-BASIC with the help of various ASM libraries. It is heavily inspired from Super Metroid for the SNES. Note that due to its innefficient code and the large amount of files, the game runs a bit slow and has a lot of input lag. Sorry for last upload: It contained the old readme files for some reasons. Hopefully this is solved now.

This is v2.0 of my Sudoku program. Features include randomly generated puzzles, rotational symmetry on puzzles for balance and aesthetics, a scoring system, and four levels of difficulty. Compatible with all major shells including Doors CS, MirageOS, and CrunchyOS. I am currently working on a save system for the next version. Note: the animated screenshot is on a TI-83+, so puzzle generation is much quicker on the 84+.

This program differentiates any explicit additive algebraic expression in the form f(x)=ax^n+bx^n+..., setting f(x) to Y1, f'(x) to Y2, and f"(x) to Y3.
With the 5.1 update, the program now turns x-terms with negative exponents into fractions. For especially long functions, an estimated time (per differentiation) is given. For more information, see my forum post at (http://www.cemetech.net/forum/viewtopic.php?p=225715)

A redesign of my Polynomials All in One math tool. Input is handled using a two-part queue string, separated by a colon. Part one indicates the operators, part two the operands. This program can chain operations, can interrupt normal math to find the zeroes (at that point), and supports derivative and integral as well. Repeated exponents and terms out-of-exponent-order do not confuse the program. Fractional coefficients supported. Negative exponents not supported. Error catching for unsupported features, divide by zero, and algorithm failure implemented. In addition, prepend the input string with "W" or "w" to activate this program's "show work" feature.
2.3 - Zeroes finding algorithm fixed. No longer glitches on non-integer coefficients.
Categorized under:
2.4 - Zeroes algorithm debugged, steamlined, and optimized. MIssing zeroes fixed.
3.1 - Options menu added. Show work moved here. Prepending input with W now turns off show work for individual polynomials. DCS/Celtic3 saving integrated (silently disables if not present).
3.2 - Zeroes finding algorithm now no longer fails when trailing coefficient(s) are zero. Rather if realizes that this means some power of X is factorable, drops the trailing zeroes, adds 0 to the set of zeroes, then proceeds with rational zeroes test as normal -
