Notable Game and Software Releases
A Mega Man PC fan game called Mega Man 2.5D has just been released, after 7 years of development!

As you'll notice in the video, it features old-school graphics like the NES games, but with a twist: The game is in 3D, with rotating camera, for a new take on the classics. In addition to that, the game features co-op and versus modes. An amazing effort by the development team!

Calculators in General
A few weeks ago, Casio unveiled their upcoming successor to the fx-CG10/20 calculators: The fx-CG50. Now they have just unveiled its French counterpart: the Graph 90+E:

Casio has thus reverted back to their old ways of renaming their calculators for the France market, with only the Classpad series and the original PRIZM models not being renamed (although the fx-CG10 was released as the fx-CG20 in all of Europe, with extra image capabilities):

fx-7400G: Graph 20
fx-9750G: Graph 30
fx-9750G PLUS: Graph 35+ (French model has more RAM)
fx-9750gII: Graph 35+ USB
CFX-9850G: Graph 60
CFX-9950G: Graph 65
fx-9860g: Graph 85
fx-9860g SD: Graph 85 SD
fx-9860gII: Graph 75
fx-9860gII SD: Graph 95
Algebra FX 2.0: Graph 100

It is widely speculated from the name that this new calculator will have an exam mode or restrictions allowing its use in French exams after the 2018 rule changes, unlike the fx-CG20, which lacked one despite OS updates.

Regarding the technical specifications of both the Casio fx-CG50 and Graph 90+E, it appears that they will feature the following:

61 KB of user RAM
16 MB of Flash
Add-in support (that can be installed by the user, but it's unclear if extra protections against third-party add-ins have been added)
4xAAA batteries required
USB and 3-pin cable support

Exact CPU specs are unknown, but the info page states something about high-speed calculations. It is unknown if any improvements were done in terms of LCD speed and especially BASIC drawing commands, which are notorious for being incredibly slow on the fx-CG10/20. The MSRP is 130 euros, approximately $30 higher than its American counterpart.

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!
