  7. Prizoop is a Game Boy and Game Boy Color emulator that is compatible with most popular titles. To install, just copy prizoop.g3a to the root of your Prizm, and any rom files you would like to play in the emulator the root as well (as .gb or .gbc files, with simple 8 character names).

    You can also compress files using the included Windows tool as .gbz and save a bit of space in exchange for slightly slower emulation.

    An embedded FAQ viewer is available that maintains your position in a text FAQ for each game. FAQ's are very readable thanks to calctype and sub-pixel text rendering. Simply include the FAQ as a ASCII encoded text file with the same name as your rom file but with a .txt extension.

    Includes full sound support (using a 2.5 mm to 3.5 mm adaptor), and can run almost all games at full speed.

  9. You love the game of Tetris on every platform, from your computer to your GameBoy to your TI calculator, so why not enjoy it in brilliant color on your Casio Prizm calculator? Featuring fast-paced gameplay, four play modes, high score tracking, and much more, this game is sure to be a permanent addition to your Prizm. In Marathon mode, try to complete lines for as long as possible as your score and the speed increase. High Speed mode ups the ante with faster drops at lower levels. If you want to start out in a bad situation, try Touchdown mode. With Collapse mode, you can set up giant stacks of tetrominos to score many lines at once. And to really torture yourself, see how long you can last with no line pieces in Sadistic mode.

    I'm sorry there's no topic for Geometry Dash on cemetech for now. For more information, take a look there :

  12. Portal. Enjoy blasting through space at breakneck speeds and almost being fried, crushed, and insulted all for the hope of cake at the end. With 78 total levels, the fun will probably end at some point. But that is why there is a level editor to make even more mind boggling puzzles. So, good luck, and remember that GLaDOS is always watching...

  19. Hello,
    I would like to introduce you my attempt to port Doom to Casio Prizm. Standard Doom requires about 8 MB RAM, so do not expect anything :-)
    It is in a very early stage, slow and it will probably crash due to failed malloc.

    arrows - movement
    [alpha] - fire
    [exe] - use (open the door,...)
    [^] - iddqd + idkfa :-)
    [F1] ~ [F5] - weapon select
    [Menu] - exit (the calculator will be in somehow wrong state, if menu is not working, try to turn it off and on)

    Uploading here on KermMartian request.

  23. Pokemon + add-in is functional and very Casio OS looking interface to view and calculate evolution of your Pokemon for Casio Prizm/FX-CG calculators.

    It's current functionality in 3 different languages (English, German and French) is:
    * display Pokedex with numbers and localised names,
    * view types, required eggs, candies or legendary attribute,
    * record your CP and HP values,
    * display maximum and evolvable ranges of CP and HP both from and to your Pokemon (i.e. reverse and not).

    I kept everything as close to Casio's OS style as I could making navigation intuitive but a few key shortcuts worth mentioning:
    UP/DOWN - increases/decreases Pokemon value by 1
    PLUS/MINUS - increases/decreases Pokemon value by 10
    MULTIPLY/DIVIDE - increases/decreases Pokemon value by 100
    DEL/UNDO - toggles between minimum (Pokemon shade view) and medium of the range value of your Pokemon

    Please leave your comments on or on any other relevant post here.

  29. I present to you, the laurels of about... maybe an hour of work... PONG!

    This version of PONG is for the Casio Prizm, very true to the original, and meeting the goals of development I planned for it:

    - under 50KB total for the entire Add-in
    - achieves over 15 FPS with decent video effects
    - entirely developed in under an hour
    - uses only routines available in the Useful Prizm Routines and libfxcg

    I did this as a proof that native development on the Prizm is very easy to do now, even without an abstraction layer like SDL. It also is meant for beginning C for the Prizm programmers to tear apart as a very easy game example, from which they can learn to make their own Add-ins.

    That being said, I also took my spare time to add in some small video noise effects to make it look cooler, and both an AI and 2 Player mode. Controls are:

    F1/F2 - menu choices
    Shift/Alpha - Player 1 Up/down
    Up/Down - Player 2 up/down
    Exit - exit to title screen

    Tear it apart and enjoy it! It's far from perfect, but it's still fun to play. If you do try to learn by improving upon it, and re-releasing it, give me some credit, s'il vous plait. And now, with comments!

  36. This game is an homage to (some might say port of) the popular smartphone game named "Flappy Bird", which through a combination of addicting frustration and word-of-mouth has achieved great notoriety. You pilot a bird through a narrow tunnel of Mario warp pipe-like obstacles, telling the bird when to fly upwards and when to fall with gravity. Although the concept is simple, playing the game is table-poundingly annoying. While I tried to make this game equally frustrating to pay tribute to its inspiration, please don't smash or damage your calculator, as there are plenty of less frustrating things you could be using your calculator for. Requires Doors CSE 8.0 or higher. See the Readme for more information and disclaimers.

  38. ADVENTUR is a game originally created in TI-BASIC for the 84+ C Silver Edition.
    It was then rewritten in AutoHotkey and expanded to have more than five times the original content.
    Once I got a TI 84+ CE, I ported the original basic code to my new calculator.
    And now, I bring to you ADVENTUR Update 4 Preview written in Assembly for the TI 84+ CE!

    This game was inspired partially by the Stanley Parable. Like the Stanley Parable, it is a game
    about choice. If you play this game with the sole intention of beating it, you are missing out. Just
    play through the game and appreciate all the content. Play it multiple times. Have fun. ツ

    Also stay tuned for the official sequel, HOARSE! (

    DISCLAIMER: I am not responsible if this game causes you to go insane. It contains several logical
    fallacies and fanciful circumstances. Do not take this game too seriously. This game is also not very extensively tested.
