  3. TI-84 Plus CE Programs

These files are for the TI-84 Plus CE, 83 Premium CE, and other "CE" calculators with color screens. BASIC programs are compatible with the TI-84 Plus CSE and some BASIC programs written for monochrome 83+/84+ calculators will also work correctly. Assembly and C programs must be written for the CE calculators specifically; running them on calculators with an OS newer than 5.5 requires jailbreaking the calculator.

  1. This program works similar to other dark mode programs for the TI-84 Plus CE,
    with the exception that it will maintain dark mode even after turning the
    calculator off and back on again.

    To enable dark mode, all you need to do is run "prgmDARKINST" from the OS
    programs menu. Keep in mind that shells (like Cesium) will interfere with this
    program, as they use their own hooks which conflict with Always Dark. If for
    whatever reason you reset your calculator, you'll need to run "prgmDARKINST"
    again to re-enable dark mode. If your calculator is in dark mode and you'd like
    to disable it, you can follow the same procedure by simply running
    "prgmDARKINST" and your calculator will be back to normal again.

    I'd like to give a massive thanks to RoccoLox Programs for being a huge help on
    this project and writing a lot of the assembly code. Be sure to check out his
    projects as well!

  2. This software is made by JustinYD88 (cemetech.net). You may distribute this software, provided this notice is included. If the software has been edited in any way, please provide appropriate notice.

    This program simulates gravitational interactions with m1*m2/d^2 and F=ma. The demo is included in the program, but you can make your own gravitational configurations by editing the [H] matrix and loading it with the 'LOAD [H]' option.

    Matrices are used to represent the objects. Each row represents an object (up to 99, the matrix limit) and each column represents a property of that object.

    Column 1: The mass of the object (negative masses work too)

    Column 2: The current X-position of the object
    Column 3: The current Y-position of the object

    Column 4: The current X-velocity of the object
    Column 5: The current Y-velocity of the object

    Column 6: The previous X-position of the object (used for drawing lines, internal use)
    Column 7: The previous Y-position of the object (used for drawing lines, internal use)

    Column 8: If circle drawing is enabled, this is the radius of the circle. (If you leave 0, the radius will be (3*mass/4pi)^1/3).
    Column 9: This is the colour used to render this object's circles and lines.

    This program uses the [G] matrix for internal data manipulation, and the [H] matrix for importing configurations.

    Included in the ZIP is the program file, one custom configuration, and two screenshots.

  3. This is a simple game where you are between
    two walls and tiles fall down from the sky.
    Move around to don`t let the tiles hit you!

    Though the gameplay looks very simple it can
    be very challenging!

    Three difficulty modes and different stats included!

  4. Original game created by students of Bud Valenti. This classic basic game is the first of a series of basic games translated to TI-Basic. The object of the game is to find 4 Mugwumps hiding on a 10x10 grid. After each guess, the program will tell you the distance from each Mugwump.

  5. This Pi Day 2013 tribute program for the TI-84 Plus C Silver Edition teaches trigonometry while you eat pie. You choose the amount of pie to eat, first an amount, then whether that's times pi or not, and finally if the angle is degrees or radians. Along the way, the program will show you the sine, cosine, and tangent, of the angle of pie you have eaten so far. A fun way to visualize angles and trigonometry.

  8. A very useful program that will let you graph equations in terms of X=, instead of the TI-OS Y= graph.
    This program is easy to use and will allow you to change most of the graph settings and window settings
    within the program itself. The program can graph up to 6 equations at a fairly quick speed (the more
    equations the longer it will take)! This program will even let you trace the graphs.

  9. This will NOT work for TI 84-Plus CSE, as the menu bug (seen in the screenshots) will make it very hard to use

    This Program will allow you to take full advantage of the clock, date, and timer features of our caculator, without needing to know any of the tedious syntax for the functions. It allows you to Set the Time and Date, view a real-time clock, use the built in timer, and preform many complex calculations, including:
    -finding the Day of the Week
    -converting a large amount of seconds to Days, Hour, Minutes, and Seconds
    -finding the amount of days between two dates
    -and much more!

  11. Version 1.0
    CEdit is a fast, powerful, and (soon to be) configurable text editor for the TI 84 plus CE.
    It takes the filename to edit in ANS, or you can create untitled files by making ANS empty.
    Unlike other text editors, it allows you to edit arbitrary appvars.
    It also supports selection, copy, and paste. Modifiers work like on computers, i.e. hold key a and press key b.
    Adds bugfixes and support for searching, CEDITRC customization, and more!

  13. V5. Sorry, I didn't upload versions 2,3 and 4 because they were really unstable and barely worked.

    Input a polynomial expression in reverse polish notation (described in readme) such as *+*:(x^2+4)(x^3+x+5)(x+4).
    Output: Simplified polynomial!

    Speed results: 15 sec for (x+1)^6, 12 sec for (x+1)+(x+1)... (3 more times).

    Operators: *,-,+

    New: uses only 3 Lists.
    Amazing Error Checking. In fact, if you can crash this, I will credit you in the Credits (If you want, if you don't want me to I'll remember you in my heart)

    Welp, We're up to 4.7 KBytes. Wut?

    It's basically that.
    The game is written in TI-Basic, for the two
    following calculators:
    TI-84 Plus CE (Physical)
    TI-84 Plus C Silver Edition (Emulated)

    More information in the readme.txt.

  17. With this program you can calculate the day of week of any given date!

    When you try to calculate on what day of the week a date was using the DayofWk( command, you might have noticed that the answer wasn't correct.
    I don't expect you'll have seen that though, but I've tested it with several dates and I can tell you it isn't correct.
    If you want to know more about this, you can read the 'readme' file.

    I've in this program made a settings part, in which you can set everything for your country.

    I really want to thank one of my classmates, who can calculate a day even out of his head, also for the Julian calendar.
    For this release I also want to thank PT_ and Fghsgh for their help.

    Current version: 1.2.1

The color one is found at http://www.cemetech.net/programs/index.php?mode=file&path=/84pcse/basic/programs/ColorTimer.zip. It is almost exactly the same. However, this one will work on both the TI-84+CSE and the TI-84+CE. Enjoy!

With 64 combinations of bases and 20 different amino acids, memorizing what codes for what is impossible and why use a weird, hard-to-read paper chart when you could use your calc! Just use the arrow keys to change the bases and the amino acid abbreviation will appear magically before your eyes! This might work for the Ti 84 Plus but I have not tested it yet.

    (Disclaimer: requires a small amount of understating of how codons work.)

  43. The Texas Instruments Flight Simulator, otherwise known by its acronym as the TiFS, is a Flight Simulator for the Ti-84 Plus CE. It is currently a work in progress. There are physics now but they're not perfect. There is also no landing gear, animations, etc.

    There are currently three planes I've made for the TiFS:
    - Cessna 172 (released for the TiFS v1.0, on March 26, 2024)
    - DHC-6 Twin Otter (released for the TiFS v1.1, on April 3, 2024)
    - Beechcraft King Air (released for the TiFS v1.2, on May 20, 2024)

    The geometry for the planes is pretty rough and wireframe, but I'm not willing to fix it.
    You cannot edit any plane files on the Ti-84 Plus CE alone, you can only do that through Ti Connect CE.

    All the plane models are available for access on Desmos, in case you want to see how the planes were made, or you just want to help me add some planes to the TiFS.
    https://www.desmos.com/calculator/j9xaxo9new

    Again, most of these features - they're a Work-In-Progress.

    CONTROLS:
    Use the Arrow Keys on the top right of the Calculator to pitch and roll the plane.
    Use the MODE Key to yaw to the left, and the DEL key to yaw to the right.
    Use the x,t,θ,n Key or the APPS Key to adjust the altimeter.
    Use the STAT Key to increase speed, and the PRGM key to decrease speed.
    Enjoy!

    TiFS v1.3 MAY EXPERIENCE MANY UPDATES AND PATCHES AS DEVELOPMENT GOES ON. The current (and most recent version) is the most stable as well.
    23/02/2025: New stable release

  46. Super-Sweeper is a MineSweeper Clone for the Ti84plus-CE written in C. Featuring 17 different variants of MineSweeper, a colorful GUI menu, custom games, and a few graphical effects here and there.

    The objective of Super-Sweeper is to safely Flag all of the hidden Mines by using the numbered tiles. The tiles will tell you how many Mines are nearby. Be careful, clicking on a tile with a Mine underneath will cause the game to explode!

    Super-Sweeper also comes with a Windows version that you can run on your computer.

    The game is currently underdevelopment, so not every feature is implemented or finished quite yet. Some of the planned upcoming features include save files, an overlay of the search pattern when chording, an endless MineSweeper game-mode, and a leader-board.

    Categorized under:
  47. A complete and faithful minesweeper clone in 10 KB.
