  6. Polynomial Solver Z

    Update: This program is an experiment, but it is very fast compared to SOLVERY, for most polynomials, and also gives you the integer second degree factors, wether their roots are real or imaginary. Instead of going about to analytically test for second degree factors, it tries to conclude which factor is right by ”looking” at the resulting polynomial and the error list. This version has 608 bytes more than SOLVERY, and fixes several bugs in the previous version. I hope to get some response from you, wether you find it ok or not. Is it worth the extra bytes?

  12. First Fantasy: Mana Force v4.5.3

    First Fantasy is one of the first RPG ever released for the TI-84 Plus C Silver Edition and the first ever one for the TI-84 Plus CE and TI-83 Premium CE! The CSE version uses Doors CSE 8.1 libraries to enhance TI-BASIC language, while the CE version uses CE Textlib and a custom font. This very loose remake of Mana Force for the 83+ brings enhanced graphics, new magic spells and enemies, new cutscenes, expanded storyline and many new challenges. There are 16 magic spells available, 7 character classes, 8 dungeons (12 in the CE version), 49 monsters (77 in the CE version) and several hours of gameplay. If you are a fan of Square-Enix Japanese role-playing games such as Final Fantasy, then you should try it!

  13. First Fantasy II: Pokéwalrus (Magenta Version)

    First Fantasy II: Pokéwalrus is one of the largest TI-84 Plus CE and TI-83 Premium CE calculator game available. It is a RPG inspired by the Pokémon, The Reign of Legends and Illusiat series and serves as an indirect sequel to Darkblasters for the TI-83 Plus and TI-84 Plus monochrome calculators and First Fantasy: Mana Force for the TI-84
    Plus C Silver Edition, TI-83 Premium CE and TI-84 Plus CE (Python models included). Set over 1000 years past two apocalypses, you live in a world where almost everything is a walrus due to radioactive fallout causing widespread mutations over time. Walruses in this world battles as many species for fame and it is now your day. However, a threat also seems nearby and it is possible that the future of this world lies in your hands.

    There are 15 dungeons, a large overworld map, 23 different attack moves, 2 healing spells, 306 playable characters spanning 10 elemental classes and it is generally more like Palworld when it comes to open-world exploration. Battles are 3 against 3 characters instead of 1 on each side.

    Requires Celtic CE library (see links).

    Hangman CE is a TI-Basic program that I created from the ground up. It's PvP, so it requires one person to input a string for the other to guess. I've enjoyed using this program myself and hope you do as well.

    I would appreciate any feedback anyone has to offer about the code itself. I'm always looking to improve so I can share even better programs in the future.

  18. Spriter

    Spriter is a simple, minimalistic sprite and icon creator for the TI-84 Plus CE
    and TI-83 Premium CE written in Hybrid TI-BASIC using the Celtic CE library. It
    features an editor for sprites using both xLibC and BufSprite palettes, along
    with options to export both to string variables and as an icon for a TI-BASIC
    program!

    You need the Celtic CE library to use this! Download it here: https://bit.ly/CelticCE

  19. Synthetic Division

    Update: This is a somewhat improved version of the original SYNDIV, with 1840 bytes, down from 1916. I am including it in the file since you are still downloading it, trying to figure out which version is best. Well, here they are, both of them. As you will see, SYNDIV1 is the better one, faster and with fewer bytes, and with the ability to enter the terms in any order.

    Making a port from TI-Basic to Casio-basic, was a bad idea. Trying to think in TI’s basic and then put it on a Casio does not make Casio justice, as you can see in the previous versions. So, I’ve made a new program from scratch, on my Casio fx CG50. The number of bytes have dropped from 1916 to 1196, and the program is much faster now. As in previous versions, you can only use x as variable, and only integer coefficients, but you can enter the terms in any order, and there can be more than one of the same degree. The lists however, are still presented one by one vertically, and the only limits for the number of polynomials you can enter, is memory and the degree of the first polynomial.

  20. HD Picture Viewer CE v2.0.0

    High Definition Picture Viewer CE is a nifty tool that allows you to utilize the TI-84 Plus CE and TI-83 Premium CE's full screen resolution for viewing images!
    Version 2 dramatically increases the resolution supported! Zoom and pan features allow most images up to 1080p to be viewed on the calculator. A picture converter is included to create calculator-compatible files.

  21. FATHER (Earthbound Inspired RPG)

    In this fan-made prequel to Earthbound Beginnings, you play as an alien the same race as Giygas, with your race's special PSI power. Invaders from other planets are attacking, trying to take it from you! As the father of PSI, it is up to you to defend your power. Use classic Earthbound attacks to defeat them, or use new items to help you.

    NOTE: This game is kind of unfinished, as there is no ending there are some loose ends. However, the core gameplay works great and is fun, trust me.

  24. Opossum Massage Simulator: Abridged Edition

    It is widely known that opossums have the instinct to repel aliens. You can now practice your opossum massaging skills on the TI-84 Plus C Silver Edition, TI-84 Plus CE and HP Prime calculators! There are three CE versions, sort-of: One of which uses Celtic CE but runs slower, an older one using ICE Compiler which no longer works with newer C library versions, a Game Boy ROM converted to appvar for use in TI-Boy CE emulator and the ROM file itself for use in a PC Game Boy emulator or on original hardware. The Game Boy version is included for use in TI-Boy CE because it runs smoother despite being emulated.

  26. The CE Casino [CC26] - Can you get all the endings?

    CURRENT VERSION (v1.0.2): Added changelog and edited readme and this description (you can now find the controls)

    The CE Casino (read me pls)
    The CE Casino was originally made as a screensaver for CC26, but I thought, this was my best code yet. So here we are, me writing this readme to send to Cemetech.
    The CE Casino (from now on referred to as CEC) minimizes user input and increases power efficiency. After all, isn’t that the purpose of a screensaver? CEC does this by only
    using wait commands and running in TI-Basic.

    What CEC is about
    CEC is about a certain man going into a casino to gamble and make more money, as he is a puny millionaire compared to the billionaires and trillionaires of the world.
    When the man either goes in debt $2.5 million dollars or gains $5 million, different story lines commence.
    5 Million Storyline: 1: Gamble; 2: Criminal Empire; 3: Invest;
    1: Lose money; 2: Get Caught/Die; 3: Lead a long, peaceful life.
    1: Merge storylines

    -2.5 Million Storyline: 1: Homeless
    1: Die in rocket crash 1: Riches to rags to riches.

    Events that can happen while gambling
    Jackpot - 10%: +550,000
    Grandpa TImmy’s Illness - 10%: -350,000
    I. A. N. Effect - 1/110: Instant death
    Grandpa’s Extreme Illness (getting Jackpot and Grandpa TImmy’s illness) - 1%: -500,000

    Controls
    [on]: To “break the program”
    * I might add [clear] to exit the program. *

    Trivia
    Grandpa TI-mmy. TI. Get it? Bad pun…
    The reason why the story’s not set in Texas is because casinos are outlawed there.

    What’s next?
    Well, I have an idea to build a collection of games based on The CE Casino. I’m also expecting to have time to expand the CEC or just take the source code and make an interactive version.

  31. Celtic CE

    Celtic CE is a library for TI-BASIC programs, which allows programmers to use many powerful commands and tools otherwise not possible with TI-BASIC. These include graphical commands, such as drawing sprites, shapes, and text, along with commands for running programs and hex code, creating and manipulating files, and more! As a successor to libraries such as Celtic 2 CSE and Celtic III on older calculator models, Celtic CE brings many commands over from past TI-BASIC libraries, along with offering full compatibility for TI-BASIC programs written to use Celtic 2 CSE. All information for commands and general usage can be found in the official documentation, which is linked in the README. Enjoy!

  32. Super Sweeper v0.80.1

    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.

  34. IGRAPHER

    this is a quick thing I made to make graphing with i easier, to use it send the file "IGRAPHER CE.8xg" to the ti-84+CE
    (or send the file "IGRAPHER SCE.8xg" to the ti-84+CSE calculator),
    then ungroup it and run the program "IGRAPHER"*, and you're done.

    meaning of what you are seeing:
    Y1:the input
    Y7:a poor implementation of a way to see X and iX of Y1 added to each other without changing the scale
    Y8:the real component of Y1
    Y9:the imaginary component of Y1
    Y0:the real added to the imaginary via nothing more than addition

    *NOTE:The "IGROUPER SCE.8xg" is only different from "IGRAPHER CE.8xg" in the way Y7 is implemented.

    updates:
    V0.1: Y7 implementation for SCE is made more consistent with the CE
    v0: first release

  35. ROOTS

    Update of the text file. The programs are the same.This file contains five programs about roots. QUADRA gives the roots of the second degree equation, plus the Discriminant and the formulas involved. A3 gives the numerical solution to the third degree equation. RADICAL gives the reduced integer roots of a number. It is fairly simple, but no slouch. RADICAL1 has all the bells and whistles. For example, to reduce the square root of 1234567890, takes 26 seconds for RADICAL, while RADICAL1 does it in about a second. ROOT gives you the numerical value for positive roots of a number. It’s algorithm is very quick and exact.

  37. BOUNCE

    A peggle-like game for the TI-84+CE.

    How to play:

    Move around the "Spitter" (the thing in the top center of the screen) using the arrow keys. This is how you aim it. You can throw from it using the "2nd" key. Hitting the pins on the screen increases your score and also the more you hit in a row, the higher the score increases for each next one you hit. You start with 20 pinballs, your pinballs increase by 3 for each level you complete. You can view the 'guidance' for the ball by pressing the "Mode" button. This will show you where your pinball will go and what pins will be hit without wasting a ball. You use up one guide, which is shown in the bottom right, for each time you use the power. You can get more guides by getting a streak of 5, then for each successive hit, you gain one guide.

  47. WEB1999: an Internet simulator

    Relive the glory days of yesteryear with WEB1999: a simulation of the Web browsing experience circa the turn of the third millennium in the palm of your hand on your TI-83 Premium CE, or TI-84+ CE calculator!

    This is a non-interactive screensaver-style program wherein assorted pop-up advertisements appear onscreen and the computer autonomously fights a battle to keep the screen uncluttered, similar to the "Realistic Internet Simulator" Flash game from 2002 (sometimes also known as "kill the popups"). Older users with firsthand knowledge of the Web around the year 2000 will find nostalgic reminder while others will receive an impromptu lesson in history, and everybody should find the results fun to watch.

    This is version 0.1c.

  48. Supersonic Ball v1.2.0

    Supersonic Ball is a simple side-scrolling platformer/tunnel hybrid where you control a bouncing ball, guiding it to the end of each level. Challenge lies in getting through narrow areas or climbing stuff without bouncing back, and it gets progressively harder to do so as the game progresses. The game features physics, randomized levels, animated graphics (or sometimes grayscale), smooth scrolling and parallax backgrounds. Try to get as far as possible as fast as you can without running out of time to get the highest score! Written in Axe Parser language. A version that runs twice faster on 15 MHz calculators is also included

  50. The Legend of Zelda: Dark Link Quest

    Ancient Zelda game made with TI-BASIC using various ASM libraries, now updated for modern linking softwares and TI-84 Plus compatibility. Since the game has dated code and predates xLIB APP, Celtic III and Doors CS 7, it has hundreds of sub-programs and a 15 MHz calculator is recommended for speed reasons.

    With the exception of games made with the Action-RPG Construction Set, Zelda DLQ is the only Zelda game project ever completed for TI-83+SE and TI-84+/SE calculators. It is semi-open-world, there are three dungeons, various items from the original games and various monsters. It is incredibly hard, though (even moreso than Breath of the Wild and the first NES Zelda), especially near Death Mountain and Zora Palace. I am no longer able to locate the code that dealt with how much damage each you take from enemy hits, so the difficulty will have to remain as-is.
