  1. MORSE ENCODER/DECODER for TI-84 Plus CE

    This is a group of TI-Basic programs and subroutines to encode/decode Morse code.

  2. HEX TOOLS for TI-84 Plus CE

    This is a group of TI-Basic programs and subroutines dedicated to base manipulation between binary/decimal/hex including a coders' calculator (supports and/or/xor), jmp calculator, and flashcards to help you to learn how to (practice) convert binary or hex to decimal in your head.

  3. HACK*MATCH

    HACK*MATCH is a fast-paced match-4 game in the vein of Candy Crush, but (hopefully!) better. Move matching files into groups of 4 to remove them and score points. Files will continue to be added from the top; if they reach the bottom, it's game over!

    Groups larger than 4 score bonus points. Two stars placed next to each other will destroy all matching files, but score no points. The higher your score gets, the faster the files will come!

    This is an ASM program written in C. It uses 8 kB of RAM and 26 kB of ARC. If upgrading from a previous version, please pay attention to the installation instructions in the readme!

  5. BaseConv 1.2

    This program can convert to and from any base between base 2 and base 36, using the appropriate alphanumeric notation. Uses a custom algorithm that should be relatively fast, and can handle numbers up to 10^99. Versions 1.1 and 1.2 are bug-fix releases.

  6. Kabufuda Solitaire

    This is a variant of solitaire based on that in the Zachtronics game *Last Call BBS*. The game is played by stacking matching cards on top of each other. Stacks of matching cards may be moved as a unit. By stacking all four of a set of matching cards directly on the table (i.e. with no other cards on top of them), they are collapsed into an immovable unit. There are also four free cells, though three start locked and are only unlocked one by one as sets of cards are collapsed on the tableau. The game is won when all cards are collapsed.

  8. RPN83P: RPN calculator for TI-83+ TI-84+ inspired by HP-42S

    RPN83P is an RPN calculator app for the TI-83 Plus and the TI-84 Plus. The app is inspired mostly by the HP-42S calculator, with significant features from the HP-12C and the HP-16C. The RPN83P is a flash application that consumes 3 pages (48 kiB) of flash memory.

    Features:

    * traditional 4-level RPN stack (X, Y, Z, T) with LastX register
    * 8-line display showing all stack registers
    * 25 storage registers (STO 00, RCL 00, ..., STO 24, RCL 24)

    * base conversions and bitwise operations (BASE)
    * 1 or 2 variable statistics (STAT)
    * curve fitting (CFIT, linear, logarithmic, exponential, power)
    * time value of money (TVM)
    * complex numbers (CPLX)
    * date, time, datetime, timezone, and real-time clock (DATE)

    * Press ENTER.

    Exiting:

    * Quit app: 2ND QUIT
    * Turn off device: 2ND OFF

    Version: 0.10.0 (2024-03-31)

    Major Changes from 0.9.0:

    * add date, time, datetime, timezone, and real-time clock functions

  13. Brainfoo - A brain**** interpreter in TI - Basic

    Brainfoo can run brain**** code on the CE. As it runs in TI Basic, it is pretty slow, but some speed improvements have been made since the previous version.

    How assembling works: The assembler reads through the string and turns each character into a number. It also searches for the loop commands so that the assembly runner doesn't have to. This makes programs easier to store and faster to run.

    Please view the BFreadme.txt file in the archive and make sure to copy ALL the programs and lists to the calculator.

    V1.2 - Made the settings menu easier to use, removed interpreted code, and added an external python compiler.
    V1.1 - Bug fixes and code cleanup
    v1.0 - Release

  16. Adds to Multiplies To

    Update: Fixed a bug in ADDMULT1. ADDMULT uses CFRAC, and ADDMULT1 uses Euclid’s algorithm to find the divisors. These programs are built on the fact that second degree equations with rational roots can be solved by dividing the coefficients in Ax^2+Bx+C=0, with A, and then select a pair of divisors in C/A that multiply to C/A and add up to B/A, then it follows that those divisors are the (rational) roots of the equation. The condition for that is of course that the root of the Discriminant is rational, as well as the coefficients. The programs are therefore showing the Discriminant and its root, as well as B/A and C/A for your convenience.

    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?

    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!

    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).

    To Hapara someone successfully, try some of these inputs: 7410, 2563, and 5978.
    To Hapara someone UNsuccessfully, try any of these inputs except for 0.
    Wonder what 0 does? You try!

    Controls:
    [<^v>] = Navigate menu
    [0][1][2][3][4][5][6][7][8][9]: Input
    [enter]: Proceed in areas possible
    [on]: Exit the program
