  1. Desert Bus II: I Am A Tree (2016)

    A sequel to the Desert Bus game included with the unreleased Penn and Teller's Smoke and Mirror Sega CD package. In this sequel, your bus crashed into a tree midway through the desert and caught fire, so you must wait 8 hours for the towing truck to arrive.

    A grayscale TI-83 Plus version of the game by JWinslow23, which plays similar, is also available at https://www.cemetech.net/downloads/files/1690

  3. Collatz Conjecture

    Collatz conjecture (3x+1) for Ti-Nspire.

    Tells you the number of iterations for the number inputted & shows the calculations.

    Maximum number that can be inputted is 9E999. Any larger and the number will be formatted as infinity.

    Screenshots show older version without the iteration counter.

  9. Complex Matrix Linear Equation Solver

    If you have a known complex matrix times an unknown column vector and you know the result in complex column vector form, you can find the unknown vector. This is a great help for nodal analysis in circuits.

  10. CPU Clock Speed Test

    This program uses the quartz crystals on the TI-83+SE and TI-84s to compute the effective CPU clock speed of the calculator. It does not work on a TI-83+. For the TI-84 Plus C SE version, see https://www.cemetech.net/downloads/files/855

  11. Ghost Tile Map

    This program features a fast tile mapping program using DCS functions to draw sprites from a picture and a matrix. It also demonstrates a fast automated ghost sprite moving around the maze.

    Bear in mind that the emulator is not as fast as on calc.

    I know that Kerm Martian already created a built-in tile mapper in DCS, but (no offense) I found it somewhat confusing so I created my own.

  14. Push The Box!

    Greetings!

    Push the Box - there was a game like this on my old Siemens S45 mobilephone, ca. 20 years ago.
    I can´t remember its name or every details, but the main goal is: fill the the last row with boxes in the Hall,
    then they disappear and you get some points. The Cranes bring boxes continuosly. You must direct the worker.
    He can push, jump up or jump over one box. Don´t let him or any box fall from too high ( 2 unit box ).
    Beware of Cranes!
    The game is end if any Crane hit a box or the Worker. Or the Worker fall from too high.
    Good Luck!

    No need external libs, start as a normal assembler: Asm(prgmPUSH
    Tested and developed for Ti83+
    No warranty for any damage!

  19. RG - Really Good

    a basic game i made while i was bored, dont expect much

    its just basic movement and a a few random numbers

    the game ends when the enemy touches you

    a brief explanation of the screenshots:

    the first is the start menu

    the ones with the + and * is how gameplay looks
    the + is the player and the * is the enemy

    the enemy movement is a random number for x and y, corresponding to the
    player x and y

    the one with game over is the game over screen
    it displays how many cycles of the game you survived

    please excuse the bad description and readme

  20. HomescreenPictures

    HomescreenPictures, in short, is a unique but simple program that allows you to take and recall pictures of the text on the homescreen. That's about it. Just note that the size of the program increases with the number of pictures you want. The current limit is 20, but I'll up it if enough people e-mail me about it. (It's tedious work, lemme tell you.)

    Update: Added some piecewises instead of many if statetments and omitted some unnecessary characters, special thanks to iPhoenix for the tips :)

    Note: The generation of a 20x20 maze takes a fair amount of time (1 to 2 minutes).

    - Calculates Quantiles from grouped dataset, using user input.
    - Draws BoxPlots from grouped dataset
    - Calculates Q1,Q2,Q3 from grouped dataset
    - Uses the basic Menu( function (dunno if that's a feature or not)

    Please read the ReadMe file for instructions on how to use it, and if you're interested in making it smaller or more efficient, I've also shared the SourceCoder3 project inside of it.

  30. Reversi

    The object of the game is to have more of your pieces on the board than the
    other player. The game starts off with two of your and two of the other player's
    pieces in the middle of the board. Each player then takes turns placing their
    pieces. You have to place your tile next to one (or more) of their tiles. All of the pieces that are in between your placement and another of your tiles get
    "flipped," or turned into yours. Once the board is filled, the game ends and
    whoever had the most pieces wins. Sometimes, there might not be an eligible
    move that you can make. In that case, you must pass your turn.

  32. Omnimaga Pack Collection (2001-02)

    Action 52 for TI calculators, but with fewer games... and yes some of them can crash (no RAM clear hopefully, though). There are some "gems" in here, though, such as Bridge Warrior, Dash 3D and Balltrix, though.

  33. zShell: A sleek, small, and powerful shell

    zShell is a shell for easy program management. It allows you to do basic functions for programs; such as archiving, hiding, locking, executing, deleting, copying, and sending to App Vars. You can also sort programs based on their size.

    This can run on the monochrome versions of the TI-83 Plus/SE and TI-84 Plus/SE. The program is less than 3,000 bytes in size and it is loaded with features. Requires Celtic III (included) to be installed. Do not use on OS 0.46.

  37. tihle v0.2.0

    tihle is a TI-83+ emulator that is designed to only use freely distributable materials; you don't need a ROM image to use it!

    This version is only tested for a small amount of functionality, so most programs will not work. A few examples that do work are included.

  39. Key Tester for TI-84+ CE (and TI-84 KE)

    This utility highlights which key was most recently pressed, and the "hold" option keeps all previously pressed keys highlighted.

    The "Normal" layout is what you would find on the front of your calculator
    The "Keyboard" layout corresponds to the TI-84 KE, as shown in this thread:
    https://www.cemetech.net/forum/viewtopic.php?p=289588

    This tool allows you to easily test all the keys on your keypad.
    There is no graceful exit, but pressing "ON" to quit also tests the "ON" button, so maybe that's a feature!

    Disclaimer, this will mess with your window and graphscreen format settings, and turns off all of your plots, and also uses a lot of the alphabetical variables, List1, and MatrixA.

  40. ABACUS CE

  42. Pure TI-BASIC color sprites example

    This is a showcase of hard-coded sprites (as in, using Pt-On and Line commands in different ways for each sprite) in TI-84 Plus CE BASIC. Higher speed can be achieved by using simpler sprites. For those with a slower, older TI-84 Plus CE or TI-83 Premium CE calculator, running DrDnar's FASTER or FASTEST program might help with the speed.

    Since this is for a project, there is also an enemy sprite and map editor included.

    The code is unoptimized since I am still working on this, but feel free to re-use and optimize this.
