  1. Core War

    This is a proof of concept of a Core War VM for the X16.
    It implements all ICWS'88 opcodes (plus a couple extra); as proof of concept it runs many of the "historical" redcode programs from that period.  It has a PETSCII arena view which follows colorized redcode programs.  Up to 8 programs may run at a time, and each may have up to 8 processes.
    It does not handle operand expression math.
    The project is here: https://github.com/bobbyjim/x16-corewar

  2. Petaxian

    I had been lurking on the forums for a few months when I found Prog8 and though this looked interesting. I.e. I could learn a new language and test out the emulator.
    I recently saw some good demos using C64 emulator but just based on PETSCII graphics and I though this looked surprisingly cool. Then I remembered the old Galaga game on the C64, the one using just (a few) petscii chars. I thought making something similar would be a nice challenge.
    The game is continuing to move toward what I consider a complete (but short) game. There are now 12 levels at which point the game will end in victory (bonus points for lives remaning). I am currently inclined to thinking that it's ok to end up with a fairly short and "completable" game. I still need to add some sort of simple high score handling. And there are always places that could use a bit of extra polishing but perhaps it would be better to spend that effort on another game.

  3. Flappy X16

    FlappyX16 is a complete port of the original 2013 iOS Flappy Bird game by .GEARS Studios, using my own assets from scratch.
    While the main reason I made this game was to get experience in C programming for X16 using a real multi-file Makefile project, I also wanted to produce a completely finished, polished game for the X16 community to enjoy. I've learned a lot about using the various subsystems of the Commander X16.
    Features:
    Four selectible difficulty levels of play Fun, addictive gameplay - Always "just one more" point to earn Keyboard and joystick support FM sound effects Bright 4bpp graphics Secret "Dark Souls" difficulty level I have not yet tested the final version using SD card images, and will update the download file if I need to patch the game. Also, my project support R39 but I have not built that against the latest versions of the master repo on Github. I will upload an R39-compatible version once I update my copy of R39 and test the build.
    I've really enjoyed making this game, and I hope the community enjoys playing it. It's a VERY addictive game. Trust me, I've spent HOURS just playing it when I should be adding features / fixing up my code

  4. Falling Snake (C)

    Simon Snake has fallen down a hole, you must rescue him, by avoiding obstacles on his way down.
    Controls: Cursor Keys, for left and right. Space to start or continue the game.

     
    Falling snake was a game that I wrote on the C64 in Basic, but now converted to KickC, because I want to add more features to it, and was
    running on the limits of what I wanted to squeeze into Basic.   All graphics, except player sprite are Petscii.  "Cut Scenes", are in "Lores Double Petscii". 
     
     
    The Basic version you can also find below as a tutorial "How to create a simple game in basic on the X16"


    This time the game is written in Kickc, allowing more features to be added.
    Current status:
    90% of all Basic features have been converted to C.
    Extra features have been added that were easier to add in C, like "cut scenes".
    Sound and more game play elements are to be added still.
    Video below.
    (music added in post production)

  5. MineX16

    This is a minesweeper clone for the Commander X16. It allows custom minefield sizes up to 38x24, with almost any amount of mines.
    To start, load and run MINEX16.PRG.
    Controls:
    Main Game Left click to reveal a tile Right click to flag a tile Click on the face to reset Press space to open the configuration screen (will reset the minefield) To exit, reset the machine (Ctrl-R on the emulator) Configuration Space to open and close Use the + and - buttons next to each digit to change the width, height, and number of mines Numbers are capped to a specific range; attempting to select an invalid value will set the number to its maximum or minimum value Click any of the presets to set all of the numbers at once Note: The game uses kernal functions to handle the mouse, so any weirdness is most likely caused by the emulator.

  6. Lemonade Stand

    I played this game with my friends in grade school on the PET.  
    Though unable to find the original, I found a stripped-down VIC-20 version -- which showed me the program's essential structure -- and the later 1986 version by Commodore, mainly designed for the Commodore 64.  I used both to create this version, which retains the original algorithms, and tries to emulate the older PET version.
    It uses very little X16-specific code -- exactly, SCREEN and COLOR.  It relies on the 40 x 25 screen, and it uses just about all 25 of those rows.
    The rest is all PETSCII and BASIC 2.

  8. Brixx

    This is a Breakout/Blockout/Arkanoid inspired game. 😀. It is my very first try on the X16.
    You have to use a mouse or a joystick (cursor keys + enter on the emulator)
    It's only tested it on the emulator (R37, R38), so if anyone of the few with real hardware can give it a go, I'm eager to know the result.
    Available power ups (no keycodes, you have to catch the dropping badges):
    [L]: adds one live to player [M]: paddle is magnetic for 30 seconds. Can only hold one ball at a time. [C]: twin laser cannon for 15 seconds, 16 rounds in a row (if you are quick). [D]: Duplicates ball, so now you can have fun with 2... Keyboard commands:
    's': sound on/off. 'p': pause game 'q': quit game. How to use with the local emulator:
    Unpack ZIP file into the same directory as the emulator. Start the emulator, then enter LOAD"BRIXX.PRG" RUN Or use the "Try now" button.
    Let me know what you think...

  11. x16Sokoban

    A Sokoban clone for the Commander x16.
    This started out, mainly to see if I could grasp the concepts behind the x16. No sounds or music, since this is a pure puzzle game.
    I have put in a fun level set called 'Sasquatch IV', publicly available at http://sneezingtiger.com/sokoban/levels.html.
    The code for this game can be found at https://github.com/envenomator/x16Sokoban.git
    Have fun!

  12. Vixx

    The project : https://github.com/VincentFoulon80/vixx
    Vixx: A bullet-hell game for the X16
    Story:
    Your Commander X16 got a virus ! Thankfully you have an antivirus called Vix that'll get rid of the evil software. You play as the Vix Antivirus, scanning the computer trying to locate and destroy the virus.
     
    How to play :
    Joystick / Arrow keys : move the player
    Start / Enter : start the game, pause
    B button / Ctrl key : Panic!
    Your score increase over time, and also when you move near the bullets.
    You score points when defeating bosses and also when panicking ( 100 points per bullets on panics)
     
    Project status :
    The game is still in its alpha phase. I'm implementing new features and do not focus on the content.
    The first level is not final, and the second is just an infinite loop. It's more to give an idea of how the game will look.

  13. Attack of the Petscii Robots (Shareware)

    This is a shareware version of Petscii Robots.  It only includes 2 maps.  It also lacks SNES controls and the cheat-code.   It is also only presented in "color PETSCII" mode, as there hasn't been a version made yet with custom graphics and sound.  The music routine is a direct port from the PET, which only uses 1 square-wave voice.

  14. Animal guessing game

    After seeing others post conversions of classic basic programs, I remembered this one where the computer plays an animal guessing game with you.
    It tries to guess your secret animal by asking questions about it, and if it doesn't know the animal, it asks about your chosen animal so it knows about it the next round!
    (It's basically building a binary search tree)
    note: all knowledge is lost when the program exits. (maybe I'll make a future version where it can save/load the animals and questions)
    Source code is here: https://github.com/irmen/prog8/blob/master/examples/animals.p8

  15. Tehtriz

    I've recompiled my tetris clone to the Commander X16!  Features:  holding area,  wall kick rotations,  shows next piece,  staged speed increase
    It is functionally equivalent to the original C64 version except the sound effects are a bit simpler.
    Controls are printed in the screen, note that you can also use the cursor keys for movement if that's more convenient for you (not printed)

  16. GRIDGAME

    (full source available https://github.com/mparson/gridgame)
    GridGame
    A game for the Commander X-16!
    A 'C' implementation of a Flash game I used to play a lot of back in the days of Flash games.
    Read about the original game here: https://jayisgames.com/review/gridgame.php
    I'd say this game is ~95% faithful to that original game.  Some of the limitations are due to my use of the so-called PETSCII character set for the graphics instead of custom graphics, which means there is no smooth animation of the pieces as they are activated.  I've also not included any sounds, but that might come in a future version.
    This is original code that implements the gameplay, I did not port the embedded ActionScript of the original SWF game.
    New feature in v0.9.5:
    Replayable boards, the "REPLAY" button will reset the board to where it was after the last "RESET", "EDIT" or "LOAD".  Try it again, see if you can get a better score from the same starting board.
    New feature in v0.9.
    Click on the 'EDIT' button and you can edit the board.
    Congratulations, you are now in the most frustrating and feature limited PETSCII drawing program ever.
    The boarder changes to '*' from the line-drawing characters. You can now click on a piece to rotate it without triggering a chain reaction. If you click on one of the '*' on the boarder, it will change the entire row or column to match the adjacent piece.
    When you 'SAVE' a board, it will not check for a previous file, it will silently overwrite it. Similarly, attempting to 'LOAD' a non-existent board will silently not load a board and return you to the editor.
    Click on 'DONE' to play the board.
    Why?
    Why write this game?  
    Well, two basic reasons.  
    First, I decided to take another run at picking up the C programming language, and like learning any new language, it helps if you have a project in mind that you want to implement.
    Why write for this platform?  Being a fan of the Commodore 8-bit computers and following the development of the Commander-X16, I thought it would be a fun platform to target.
    Compiling the code
    This was developed with the  cc65 compiler, so, you'll need it installed.  I tend to work with the latest version out of git rather than one of the binary packages, so, YMMV with getting it compile if you use a potentially older version of the compiler suite.
    Edit the `Makefile` and fix the paths to the various binaries at the top.
    A simple `make` should give you a `GRIDGAME` that you can now load up on an X-16.
    It should be a minimal effort to make a C-64 and C-128 version as well, probably coming soon.
    Notes on the kwalitee of my code
    Yeah, very intentional bad spelling there.  I make no claims to my skills as a C programmer.  This is probably not "good" C code and most definitely not optimized in the suggested ways you should when writing for `cc65` compiler and the 6502 CPU.
    Potential features for future versions:
    * Versions for the C-64 & C-128
    * Sound - I'll need to read up on how to make cc65 generate sounds.  It's documented, but I've not tried that yet.  Step 1 was to get the basic game working.
    * See if it will compile with KickC, then all dev work could even be done on the system it is played on!

  19. TextElite

    Imagine yourself, commander Jameson, in the cockpit of the Cobra MK-III with 100 Cr. in your bank and stationed on Lave, one of the more well known colonized planets. You're setting out to be a master trader and to get rich by exploiting commodity markets across the galaxy!
    This simulation engine is very faithful to the original procedural universe algorithms found in the actual Elite game.
    There are 8 galaxies to explore, each containing 256 totally different inhabited planets that you can travel to. Each planet is named, has certain government types and inhabiting species, and you can read a short description that characterizes the planet and what it is famous or notorious for.  Of course every planet has a commodity trade market, and you have to exploit the various supplies or shortages and price differences to make your fortune!  
    A simple navigation star map of the local cluster and full galaxy is also available.  You can save and  reload your progress to continue at a later time. 
    Source code here https://github.com/irmen/prog8/blob/master/examples/textelite.p8  Written in Prog8, converted from original C source code obtained from http://www.elitehomepage.org/text/index.htm
    (this game can also run on the C-64 if you recompile it for that machine target)

  25. Rogue Forest

    This is a work in progress, which means there's lots of missing functionality, the UI is rough, there are unfinished bits, and there's no "win" or "lose" condition, yet.
    The map is revealed as you explore.  There are two kinds of treasures -- weapons and armor -- and one special treasure: the Amulet of Yendor.  The goal of the game *will* be to find the Amulet of Yendor and exit the forest with it.
    There are 31 monsters in the forest.  They (currently) are not differentiated, except by name.
    Movement is via the cursor keys.  Trees are impassable.  "Bump" a monster to attack it.
    There are no special commands, yet.
     
    I will add some sound effects before promoting it to 1.0
