  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.


Available subcategories:


  1. A collection of pictures and usable backgrounds. This may be updated with more media in the future. When updates come, make sure to read the "CHANGELOG.txt" to see what was added. This version includes Cheetahmen, Mario, Zelda, and Lake Tahoe.

  2. Memory Editor allows you to edit the memory of your calculator easily. To install it, execute Asm(prgmZHEDIT). To display the menu which will enable you to edit AppVars (archived or not) or to begin the edition wherever you want, you just have to press Alpha+VARS.

    KEYS (in the editor) :
    Up/Down/Left/Right : moves the cursor
    Alpha + up/down : scrolls faster
    1/2/6/3/4/5/6/7/8/9/0/A/B/C/D/E/F : inserts a number at the cursor location


    This program is licensed under the WTFPL.
    Memory Editor has been extracted from PHASM.

Now the game can generate the same world from the same seed! v2.13.2: Fixed a game-breaking bug, fixed input problems. v2.13.0: Added gravel hills (in the sky) biome and garbage collect handler.

  6. A033 is a puzzle/exploration game written in pure TI-Basic for the homescreen of TI84SE and TI84CE. The objective of the game is to move the player character (pi) to collect points by earning (+) and (*) items, and avoiding contact with enemies (e), (i), and later in the game (n). By finding a stick (/) you can defeat enemies, and earn more points. When an adventure is ended, your highscore is saved and your moves are counted. There are 4 main worlds to explore, and 4 smaller bonus worlds.

    Please note that this program requires the five included subprograms to function correctly. c:

  11. Abba caving is an event done in Minecraft where the event handler finds a cave that looks like it will span down to level 15 or lower, and has users join them on a caving quest for a limited amount of time. The goal is to gather ores for various types (like diamonds, emeralds, lapis, gold, etc) and when the time limit hits, return back to the start point and the items get dumped into a chest for that player, where it gets counted and points awarded. After several such events that has been held on the Cemetech MC server, and having difficulties getting values sorted, this project was devised to speed getting scores for each player in the event, and to provide an accurate value of such. This program also comes with a timer that you can adjust from 15 minutes to 60 minutes, so you don't have to track time yourself. Happy caving!

  12. Pieman7373; Newton’s Method
    This program was initially created in November 2016 by Kaleb Allinson (My AP Calculus teacher), but i looked at the code and said that i could make it more user friendly to normal (non-calculator savvy) folk, so he let me. This program is for using Newton’s method of finding the x-intercept(s) of a function in Calculus. THis program will work on the TI-84+(SE), TI-84+CSE, and TI-84+CE calculators. Enjoy!! :D

  15. This program is directed towards novice programmers looking for alternate input methods and the use of TextLib. What started out as a simple task of making a high or low game quickly turned into a challenge when my teacher said he could "break" any program. So I whipped this up to show that it is unbreakable. See if you can find any bugs! Aside from wanting to play the high or low game, please look at the code to see how you can learn to make alternate input systems. Try to optimize it! Hopefully you can learn or get some practice from the code (which is my goal ^^) NOTE: You must have a ti-84 CE calc, with OnBlock by MateoConLechuga and TextLib by DrDnar (download separately)

    are coins labeled C you start with 50 of these and collect
    more from bonuses at the end of levels these coins can be spent
    after levels to buy power ups (you start with a drill power up by the way)

  25. Enter a polynomial. Same syntax as PEMS. However, this has one crucial change. One that took weeks of working on the engine...


    While PEMS has support for expressions like *:(x^2+x)(x+45)

    ExpandCE can expand expressions such as *:(x^2+5y^2x^5z^2)(99B^2*54x^3)

    Warning: This is an early release. There will be bugs. If you see one, please PM me.

    Note: This is SSSSLLLLOOOOWWWWW. The engine has a lot more work to do. While I'm working on speeding it up, if you don't need multiple variables don't use it.

Fun stops when a key is pressed. Just something fun I was playing with to learn about the Circle( command and how it uses colors. Plus it's nice to see how it interacts with the other circles already drawn out.

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

    Sorry about the error bug in screenshots,I had to use a TI-84 Plus CSE emulator, and those still have the menu bug. THe program looks fine on the 84 Plus CE, however.
