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!

Notable Game and Software Releases

I have been very busy lately, developing a complete replacement main board that will fit into the empty shell of a TI-84+. This will enable you to build your completely own, Linux powered, TI-84+
You almost can't differenciate the original from a modded one.

It features an ATmega328P-AU Arduino Uno compatible keyboard processor and power management controller and real time clock (to keep the time running, while the Pi is turned off).
This will be a two board solution. There will be an upper and a lower board.
On the upper board, there is space for fitting a Raspberry Pi Zero (W) and a 128x64 monochrome/grayscale LCD that I would provide. The bottom half of the board (including keypad matrix, RTC, Uno and the Adafruit PowerBoost500 for LiPo operation) will be attachable to the upper board through a few solder links. Therefore you can decide whether you want to provide your own single board computer or if you want to go for a Pi Zero and my preferred, matching LCD.
The headphone/Link jack will either expose the Pi Zero's analog video signal plus one GPIO pin or the  I2C bus, depending on solder jumper configuration. The Uno is connected to the Pi via SPI and UART. You should be able to reflash the Uno from the Pi, if you disable the Linux console on the serial port.
Otherwise, the serial console will be displayed on boot in a serial terminal mode of the Uno.
The Uno is also connected to the 128x64 screen and will go into high impendance mode to let the Pi access the screen, once the Pi is booted and ready.

I guess I can already warrant a sneak peak at the keypad matrix ;)

I hope there is demand, and if there is I may offer a kit or the bare PCBs.
If someone does not like to solder SMD, I could also offer individual assembly of the boards.
There is also need for a good name. Currently I have settled for "Pi84--", but feel free to post any suggestions if don't like the name.

From a price perspective, the bottom board with all components (except for the Adafruit PowerBoost 500) may end up costing around 12€. The power boost is available for about 15€ and a matching battery will cost under 10€.
The top board may probably cost around 18€ (not including the Pi Zero (W), but including the screen).

Dead TI-84+'es are often available at your school/uni for free or just a tiny fee, if there is a renting program available. On eBay, used TI-84+'s with a broken screen can be bought for as little as 10€.

So, in total, you will probably be paying about 65€ for your own, Linux enabled, fully hackable, state of the art, calculator.

And of course could you run one of the TI-84+ emulators on there if you wanted to ;)

Note, that this is the actual, project releated topic, while my original post was posted in another topic here.

Well, you might have noticed the pink notice at the top of the page.

Quote from: xlibman
Dear visitors and members, with the staff having moved on to other life interests and as a result of changes in people's internet usage habits, the CodeWalrus community have migrated almost entirely to Discord, IRC and WalrusIRC and is now essentially a place where to hang out, chat about gaming, programming, music, anime, and chill. As a result, even though the CW forums will remain open for posting, for faster TI, Casio or HP calculator help and news we recommend using the bilingual TI-Planet forums instead.

We encourage everyone to join our Discord server now.

Yeah. Let's face it, posting is quite low these days and none of the admins have motivation nor time to even write this post to manage and improve this site other than the minimal moderation and maintainance, so yeah, we'll still give it minimal maintainance for the time being until things get better or it just becomes a ghost town. (Which we hope not.)

Don't panic, though. It's still going to be the fun place to hang around and share your projects as long as there's any people here, on the forums or on IRC/Discord. It's just that, if you have a question, don't expect an answer right now, if you don't get it you might as well try again on TI-Planet. (Yes, they speak English, don't worry.)

Of course, that doesn't mean we won't throw some events once in a while, we might do that actually, so stay tuned for further announcements! Until then, I dunno, invite your friends, and feel free to give us some suggestions, we might actually consider them :)

Art and Music
After 3 years of wait, Hardcore Spectrum Disorder is finally out!

It contains mostly tracks created last spring and this fall, including the two major tracks Hardcore Spectrum Disorder and Rejection, which came out on September 27th 2017 and December 1st, respectively. But also it contains some older tracks, including the power metal songs Destination 1999 A.D and Elemental Cross.

The album can be purchased or streamed on Bandcamp and you can get the entire discography at once for 50% off.


I hope you enjoy this blend of power metal, retro gaming music and electronic dance music and I encourage you, like the backcover says, to donate to Fédération québécoise de l'autisme to improve support and knowledge about autistic people in Quebec!
