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!

Calculators in General
People on Cemetech have analyzed TI-84 Plus CE Flash applications that Texas Instruments released a few days before. It appears that they contains a 2048-bits signature. The signature key is required to sign APPs and make them valid for use on the new ez80 calculator, and there is no sign that Texas Instruments have any plans to release a SDK to develop such software.

Since factoring an key this large is impossible with today's technology, could this mean that the TI-83 Premium CE and TI-84 Plus CE will be locked down against third-party Flash APPs and be restricted to only a few developers such as TI themselves? ASM programs are possible to write no matter the outcome of this, so 3rd-party ASM development on those new calculators is perfectly safe, but in some cases, choosing a 8xp ASM file over a Flash  APP is not the ideal situation, especially if TI decides also to add an executable code limit to that new calculator line, like the 8 KB limit on the TI-83+. Or could TI be planning a paid SDK? After all, back in the early 2000's, Flash APP development costed money before TI finally decided to make the SDK free of charge.

In conclusions, there is a possibility that for the TI-83 Premium CE and TI-84 Plus CE, we might be limited to the Asm() command to launch native language softwares.

Normally, as soon as a new version of Ndless comes out, a new TI-Nspire OS is announced shortly afterward. This is the case again after Ndless 3.9 release :P


It apparently comes out on March 26th 2015. Note that this OS drops compatibility with the grayscale TI-Nspire handhelds. However, the writing was on the wall for many years, as newer OSes kept growing in size, to the point where those using OS 3.9.1 would only have about 2 or 3 MB of free memory available for their programs once Ndless was installed. This means, on the other hand, that Nspire Clickpad/Touchpad users will be able to stick to an Ndlessable OS as long as their school allows grayscale TI-Nspire models!

The OS 4.0 announcement page advertises the usual anti-downgrade protection, although it also comes with many new features. Ideally, you should wait before upgrading until a new tool such as DowngradeFix is released, in case you want to downgrade back to OS 3.9.1.

According to a post on the HP Prime blog, it appears that this is the end of the line for the HP 50g calculator. Should the post reveal to be true, then HP will cease production of the HP 50g this year, to focus on the HP Prime. So after 15 years, the reign of the HP 49/50g series seems to be over.

This could probably have explained why there have been quite a few hot deals on the HP 50g lately, sometimes being offered for as low as $50. In any case, there will most likely be much more. It's a shame that the calculator has not taken off more than it did among developers, though, although it was very popular among engineers. Hopefully HP adds more engineering tool to the HP Prime firmware in the near future as a compromise to this loss.

Well, that was quick. As we said, we had some staff departures today:

- aeTIos lacks the time to do any admining, he therefore resigns;
- Streetwalrus don't have any time either, he takes a hiatus and may come back to the position at a later date.

So we're now in severe understaffing, as a result, we decided to close the site and made a closing post. However, as we decided the fate of the website, we concluded the best course of action would actually to leave it open for as long as I can afford hosting it... So it is my pleasure to welcome you back to CodeWalrus, but it's not without some changes:

- Juju is appointed Supreme Overlord of CodeWalrus (er, wait, that sound's a little scary... Let's just say I'm the head honcho here). I takeover the website and I'll pay for it with my economies and the free credits I have left in my account. If you feel generous enough to help, I take Paypal and credit over here :P

On the goal of the site, CodeWalrus gives programmers, artists, hardware and software hackers and the like a fun hangout to discuss together between geeks of projects in progress or just whatever, not just about TI, but yeah pretty much everything. The same rules applies under what's left of the administration, so nothing illegal, although I advise crossposting your projects on our friends at Omnimaga and Cemetech.

So, welcome back on CodeWalrus!

Notable Game and Software Releases
17 years after Texas Instruments released it, the TI-89 finally got a fully complete Zelda clone, playable from the beginning to the end!  :w00t:


You can download it here: http://www.ticalc.org/archives/files/fileinfo/463/46319.html

Only two finished Zelda games exist for the TI-83 Plus series, which are Zelda: The Hero of Hyrule and Dark Link Quest, and they came out in 2004, after many people failed to complete a Zelda project for the TI-83 Plus series. The former uses the ARPGCS engine, is written in French and lacks many elements from Zelda (such as hearts, items, etc), but has very great graphics, Ys-like gameplay and fast speed. The latter was written by me and uses hybrid BASIC language with very old ASM libraries resulting in slowdowns and lower quality graphics, but has most features from older games. This new TI-89 Zelda game is also one of very few 68K game to get released in many years.
