Notable Game and Software Releases
A bit less than a year ago, on February 19th, 2016, Ndless 4.2 was released. This version added compatbility with the then-latest TI-Nspire CX OS version, OS 4.2.

Ndless is the TI-Nspire's "jailbreak", which makes it possible to run programs much more powerful than those allowed by TI's approved tools (Basic, Lua), by taking advantage of native code (C/C++/ASM/etc.).

Unfortunately, on August 18th, 2016, Texas Instruments released the OS 4.3 version, which blocked the ability to install Ndless 4.2 and additionally forbade going back to OS 4.2.
That was a very unwelcome gift for users who accepted the update without being aware of the consequences, as well as a growing proportion of users since then, given that brand-new TI-Nspire CX calculators started coming preloaded with OS 4.3 months ago.

In fact, it's the usual scandal, going in dramatic ways against users' interests, because it forbids programming with Python for their school needs (multiple French high school classes / projects, etc.), or protecting their private data contained in their calculators from some exam watchers illegally allowing upon themselves to go through the calculators' contents, making snapshots and adding them as proof in their fraud reports, as reported over the past few years.

Three days ago, the OS 4.4 version was released, still based on the same philosophy of forbidding valid and legal usages :(
This version created a hearbreaking dilemma, as for once in a while, the new version brought multiple new, really useful features ! :'(

However, clearly, a vulnerability was found, and it took the Ndless team only 3 days to release the retaliation to Texas Instruments, the new Ndless 4.4 version !  :thumbsup:

As indicated by its version number, the install program targets OS 4.4, with this time, lots of humor and references aimed at poking fun at and taunting Texas Instruments :P

nSonic2MS, the program making it possible to prevent exam watchers browsing the machine to find stuff, was also updated for OS 4.4 compatibility.  :thumbsup:

For those fortunate enough to own TI-Nspire CX calculators with hardware revision V or older (assembled until October 2015), the ControlX boot manager was also upgraded for compatibility with OS 4.4 et Ndless 4.4. It's executed at Boot1 level, i.e. long before Ndless, and offers
  • in theory, full control over the calculator - everything is imaginable  :love:
  • in pratice:
    • automated reinstall of Ndless 4.4 upon every calculator reboot  :love:
    • the ability to reinstall an older OS version, and therefore fix the calculator, even if you updated by mistake the calculator to a future OS version preventing Ndless 4.4 from working and getting back to OS  :love:
    • many other things - ControlX 4.4 is a major version bringing new abilities, too many and too rich to list in this article - they will be detailed later in a news item dedicated to ControlX 4.4  ;)
Don't miss your chance - if you have a TI-Nspire CX, take advantage of the fact Ndless 4.4 can, at the time of this writing, be installed on all TI-Nspire CX calculators worldwide, to install ControlX, and nSonic2MS while you're at it (don't make a gamble on exam watchers not doing illegal stuff) !

In 2017, for the last French exam session where the unfair exam testing mode won't be used, you'll be able to take advantage of Ndless like your older peers - on the condition of not accepting a possible future OS update, should Texas Instruments produce one in the meantime.  :thumbsup:

Notable Game and Software Releases
A few years ago, @Vogtinator released crafti, a 3D Minecraft clone for the TI-Nspire CX featuring many elements from the original game. Then last year, it was ported to the GCW0 by @gameblabla . However, after the GCW0, he has now ported it to the Sega Dreamcast console, which has quite a following among homebrew developers. His DC port of the game has recently received a lot of following and made the headline on various Sega Dreamcast news websites and communities:


As you can see in the video above, despite this game console featuring only 16 MB of RAM, crafti Dreamcast edition runs fairly smoothly. Good job to gameblabla for the port and of course Vogtinator for the original version of crafti!

Notable Game and Software Releases
For the last few years, @123outerme has developed various pure and hybrid TI-BASIC calculator games for the TI-83 Plus and later the TI-84 Plus C Silver Edition. Among those, there were many games with various role-playing game elements. Source Seekers, Solius and Dragonsglid were some of his most prominent titles around that genre. While simple in general, they still managed to provide a lot of entertainment while they lasted. Today, the author has released another RPG, this time using xLIBC, called Sorcery of Uvutu, for the TI-84+CSE!

Initially developed as a direct sequel or remake of Dragonsglid, Sorcery of Uvutu later evolved into a full game of its own (although still tied to the Dragonsglid and Source Seekers universe), using nice-looking graphics, sprites, tilemaps and featuring even more elements from Final Fantasy, Dragon Quest and proving once more that such game is feasible within the limitations of the 21.7 KB of user RAM on this calculator. While the story is simple and the game relatively short (about two hours of gameplay), the world to explore is still quite large per calculator RPG standards and the game should be simple to get into. In addition to that, calculator RPG projects usually tend to never get close to finished, so props to the author for making this game one of the exceptions.

A welcome addition to this calculator RPG library!

Calculators in General
Casio has recently announced that a new Casio PRIZM calculator, under the fx-CG50 model number, will be released this Spring. Amidst speculation from community members that this calculator will ditch support for third-party ASM and C development (which was unnoficial to begin with on the fx-CG10/20, but Casio left the door open on those calculators, while locking it down on the fx-CP400) and that the BASIC language will not see any significant speed improvements, here are some of the announced improvements:

-New case design, more rectangular than round
-3D graphing with many features, including zooming and rotating
-Improved catalog so that users can use commands more easily

It is unknown if the CPU will be the same as the PRIZM or if it will be upgraded to the one used in the ClassPad II, which is twice faster.  The memory capacities and whether the 2.5mm jack remains or not are also still unknown. The MSRP will be around $100 USD and many features from those calculators, such as picture plotting (graphing lines over a real life photo) will return in the new calculator. Let's hope that the door will still be open for third-party add-in development and that the BASIC language speed during drawing will be improved (for example, the 58 MHz fx-CG10/20 took 300 milliseconds to draw a pixel or horizontal line, while the 15 MHz TI-84 Plus C Silver Edition took about 10).

Hey, so I've heard you like VVVVVV ? I bet you loved Veni Vidi Vici. No ? Well here is a game consisting of 10 levels based on that singular part, named Veni Vidi still struggling to Vici ! Have fun !


VVSSV is programmed in Haxe with HaxePunk, and is a little side project I did to take a break from nKaruga. I should be back on that now.
