Welcome to CodeWalrus: A software development community with a focus on retro-gaming, music and pixel art on various mobile platforms, including graphing calculators, as well as game consoles and PC.

Since October 2014, our active members and staff have released several new games for the Sega Dreamcast, Panasonic 3DO, Atari 2600, TI-84 Plus, TI-84 Plus C Silver Edition, TI-84 Plus CE, TI-Nspire CX, TI-89, TI-92, TI Voyage 200, HP Prime, Casio fx-9860G, Android phones and computers. This includes First Fantasy: Mana Force, Sorcery of Uvutu, Reuben Quest: Lost Between Times, Oiram CE (a Super Mario clone), SQRXZ CE, KillMinds, VVSSV, Line++, Lazer 2, GalagACE and Wal-Rush! Various existing games, such as This is the Only Level, Androides, Billybox, Mandragore, Bejeweled, Flappy Bird, Pac-Man and Pac-Attack, were also ported to TI calculators by our users and various retro gaming console emulators (SNES, Turbografx-16, Sega Genesis, Master System, etc) were released for the TI-Nspire CX.

Aside from game development, our participating forum users have released notable tools such as ICE Compiler, Houstontracker 2, CEmu, the C SDK and Libraries for the CE. We also have our share of musicians and pixel artists as well, along with a massive database of MTV Music Generator series songs from the remains of TIMGUL. A lot of new projects are also active in the development section, ranging from new games to programming utilities and 3D engines, so expect new releases at any moment. Make sure to visit the authors' topics to voice your suggestions and encouragements!

We intend to provide a friendly place to discuss your favorite topics, to hang out and to showcase your projects and releases, so hopefully you feel at home here. Registration is free and only takes a few seconds!

Due to lack of users and the fact that almost everybody who use #CodeWalrus IRC channel are already on EFnet,  Omninet or using one of the two forum shoutboxes, we have come to the decision to discontinue Freenode support and linking for #CodeWalrus. From now on, in order to use the #CodeWalrus IRC channel, you will have to use one of the following method:

-Connect to EFnet then join #CodeWalrus
-Connect to Omninet then join #CodeWalrus
-WalrusIRC (main website IRC shoutbox)
-OmnomIRC (alternate one available via your profile group membership settings)

The IRC relay bot that links all the four above will also be renamed to something shorter to improve readability of IRC conversations when chatting from an IRC client. But it will no longer connect to the Freenode network, so anybody who joins #CodeWalrus from Freenode from now on will not be able to chat with us anymore.

We invite everyone who idles in the Freenode #CodeWalrus channel to switch over to one of the EFnet or Omninet servers (although this should not be a serious issue since almost all of you already use other IRC channels on those networks or are using WalrusIRC).

Tonight marks the arrival of the CodeWalrus Programming Newsletter! Those will summarize some of our big happenings, as well as some other major community material such as new calculator releases. The first edition that just came out covers the Winter season that just ended and there will be a newsletter at the end of every season, meaning that the 2nd edition will come out at the end of June.

The CodeWalrus Programming Newsletter - Winter 2015 Edition

A new sub-forum that will contain all newsletter editions was created here: http://codewalr.us/index.php?board=32.0
Link to the Winter 2015 edition of the CWPN: http://codewalr.us/index.php?topic=358.0

(Due to how the site was setup before, members who have signed up prior a certain date were subscribed by default. If you do not wish to receive such newsletter via e-mail, go to your profile, click Notifications then uncheck the forum announcement options. Thanks to a SMF plugin, people who sign up normally now have the option to disable announcements from the start.)

Calculators in General
The TI-84 Plus CE, which replaces the TI-84 Plus C Silver Edition, has been released and various TI community members such as tr1p1ea, author of xLIBC, have finally gotten their calculator in the mail!


This means that other stores will most likely have it in stock soon and eventually the new school device will make its way to brick and mortar stores. The MSRP is $129.99 and the calculator features the following:

-eZ80 processor
-150 KB of RAM (huge improvement over previous TI-84 Plus series calculators)
-3 MB of Flash
-320x240 color LCD that supports 16bpp, 8bpp and more
-OS with more features
-Considerably faster screen refreshing (especially in menus and the program editor)
-BASIC, C and ASM support (a third-party language called ICE is also available and is similar to Axe on monochrome models)

However, no SDK yet and some ASM functionalities are rumored to not be available. The biggest advantage of this new calculator model will lie in the much faster screen and larger user RAM, so pure TI-BASIC and pure ASM programmers will benefit the most. UPDATE (November 11th 2016): The calculator supports BASIC, ASM, C and a third-party language called ICE, all in 8xp program format. Flash APPs are not available, as TI has decided to not release the 2048 bits RSA key and current technology makes it impossible to factor a key this large. But this should not be a problem, as people managed to find workarounds, such as for parser hooks.

-TI-BASIC: TI-83/84+/CE Basic documentation
-Hybrid TI-BASIC: Sprites v3.3 | CE Textlib
-ASM: eZ80 assembly documentation for the CE
-C: C Programming Toolchain, libraries and resources for the TI-84 Plus CE
-ICE: ICE Compiler and its documentation

-Sprite graphics converters: ConvPNG (for use in ASM/C/ICE) | Sprite Ripper (for use in TI-BASIC with Sprites v3.3)
-Emulation: CEmu emulator (requires a ROM dump from a real calculator)

I invite owners of the TI-84 Plus CE (as well as owners of the TI-83 Premium CE when it comes out) to share their discoveries about this new calculator series in this topic or on the forums, be it ASM tricks, bugs or other useful information.

Notable Game and Software Releases
I just saw this a few minutes ago: https://play.google.com/store/apps/details?id=com.hp.primecalculator

Basically, you can now "emulate" the HP Prime on Android devices, courtesy of HP!  :thumbsup:

Hello again! We haven't posted any updates since November so there is a lot of news for you:
  • New contributors! We now extend thanks to kedarbramhe, Hugo "s0r00t" Courtial, Francis Lewis, Noah "Ivoah" Rosamilia, Kevin Lange, altbdoor, Justin "Jnesselr" Nesselrotte, Bjorn Neergaard, Willem "willem3141" Sonke, and Andrew Boos!
  • New games have been ported: ports/ztetris (thanks unlimitedbacon!) and ports/rubik (thanks Ivoah!)
  • New software from boos1993: community/progcalc is a programming calculator app that lets you do integer math on KnightOS (thanks boos1993!)
  • community/calendar has been added to the default distribution (thanks willem3141!)
  • We have redesigned knightos.org to be prettier and such (thanks altbdoor!)
  • There is a KnightOS wiki now (thanks boos1993!)
  • Users can upgrade their OS through the settings tool without pulling a battery (thanks, SirCmpwn!)
  • Lots of improvements have been made to PKO (packages.knightos.org) (thanks boos1993!)
  • Date/time support in the kernel is nearing completion, settings has been updated to support it as well (thanks willem3141!)
  • We've started working on calcsys (thanks, SirCmpwn!)
  • Our new assembler/linker, scas, is nearing completion. It will be released as independent software when it matures. (thanks, lots of people!)
  • The castle is maturing, and now lists app manifests from /var/applications/ so you can run any installed app. We've also made /var/castle/pin-{0-9} symbolic links to app manifests, which defines the apps pinned to the home screen. (thanks, SirCmpwn!)
  • We have partially implemented the KIMG format and produced a tool to convert most image formats into KIMG files. (thanks, neersighted!)
  • We have started work on a text editor called "bed" - Basic EDitor. (thanks, lots of people!)
Pretty pictures:

This time around, I'm pretty sure most of the work was NOT done by me, which is a first :) Thanks everyone!
