In conclusion, jsTIfied is safe, Wabbitemu is safe, VirtualTI is safe, TiEmu might be safe, but TI8xemu is not (since ROMs are included in it). TI8XEmu doesn't include any rom. It's just that the app can be given URLs to load a ROM and a RAM backup to start with.

Is this really a new addition to TI's legal agreement? I could have sworn I read that same line like 8 years ago when I downloaded an OS for my TI-89.
Was a little harder, but this time I found back the old english EULA on the web archives. June 2012: TEXAS INSTRUMENTS APP SOFTWARE LICENSE AGREEMENT
By downloading the software and/or documentation you agree to abide by the following provisions.
License: Subject to your payment of any applicable license fee, Texas Instruments Incorporated ("TI") grants you a license to copy and use the software program(s) and documentation from the linked web page or CD ROM ("Licensed Materials").

Restrictions: You may not reverse-assemble or reverse-compile the software program portion of the Licensed Materials that are provided in object code format. You may not sell, rent or lease copies of the Licensed Materials.
[...] No mention of emulators. Complete EULA here -> http://web.archive.org/web/20120626143305/http://education.ti.com/calculators/downloads/US/Software/Detail?id=6014&ref=/calculators/downloads/US/Software/Search/Results?cp%3D2%23view-1So they did change this in the last 6 months.

Not sure if they changed this last week, last month or last year, but they did change this recently.

It is commonly held, and explained on many sites distributing ROM images (for instance for gaming consoles), that downloading them for emulation purposes is legal if one has the hardware containing said ROM image. Actually, the problem is much more complicated, and this "rule" is not legal, in the sense that it's not part of any piece of law. At the end of the previous century, the TI calculators community spent significant effort on producing TI graphing calculator emulators, in which each user had to manually enter a ROM or OS image retrieved by his/her own means. That way, emulator authors passed legal problems (if any) on to their users. Over the last few years, many changes have occurred in the emulation field: - many community emulators of various quality and completeness have blossomed for smartphones and tablets
- the community now provides online emulators, which largely free users from compatibility headaches between computer types or installation procedures (let's mention TI8XEmu on TI-Planet or jsTIfied on Cemetech)
However, things also evolved on TI's side: - TI started to take seriously the simulation (less advanced than emulation) of their machines, through the Nspire software (or TI-SmartView for pour TI-83+, TI-84, TI-73, TI-Collège Plus, TI-30X MultiView, TI-30X Pro MultiView, TI-34 MultiView, which are quality software)
- TI offers some sort of online Nspire simulator, through the TI-Nspire Document Player
- TI recently started to sell a Nspire simulator for the iPad
In this context, as mentioned on #cemetech, a "small" change has just been introduced in the TI-Software/App license, presented to users when downloading an OS from TI's site: TEXAS INSTRUMENTS APP SOFTWARE LICENSE AGREEMENT
By downloading the software and/or documentation you agree to abide by the following provisions.
Licence: Subject to your payment of any applicable license fee, Texas Instruments Incorporated ("TI") grants you a license to copy and use the software program(s) on a TI calculator and copy and use the documentation from the linked web page or CD ROM (both software programs and documentation being "Licensed Materials"). In addition to the copy resident on your calculator, you may keep a copy on your computer for backup / archive purposes only.
Restrictions: [..]: You may not use the Licensed Materials on any emulator of a TI calculator unless the emulator is obtained from TI. Yup, from now on, using TI's OS images with community TI calculator emulators is forbidden, which is in complete contradiction with the simplistic rule mentioned at the beginning of this post. :'( Of course, we can think of the fact that no-fee virtual calculators that emulators provide conflict with calculator sales: why buy a physical calculator when one can have a virtual calculator on the computer for no fee ? Several years ago, the "problem" didn't exist, but nowadays, smartphone or tablet are computers with a form factor not larger than calculators (and they're much more powerful !), so the situation changed... Some persons will say that TI needs to evolve instead of taking part in downhill battles... But however, let's try to look beyond the facts, as there might be even more important issues at stake. So, as we're now allowed to use ROM and OS images only with emulators provided by TI... would this mean that TI intends on investing even further in the area of simulation and emulation of their products? We're impatiently and excitingly awaiting: - an online TI-84+ emulator, in order to replace TI8XEmu (TI-Planet) and jsTIfied (Cemetech) which we seemingly no longer have the right to use
- a 89/92+/V200/89T emulator
But we can also wish that TI removes such clauses... Situation to be watched... Source:#cemetech via http://tiplanet.org/forum/viewtopic.php?f=49&t=11296&p=135986Edit: Indeed, TI is planning an online TI-84 emulator for the PARCC mathematics assessments for High School as you can read here (in french):

Thank you DJ_O for adapting and posting the news here. Note that unlike the TI-84+CSE, the TI-83+.fr keeps using the new TA1 ASIC with only 48KB RAM instead of 128KB on the older TA2/TA3 ASIC.  Order your calculators from France: You'll get a TI-84+ at the price of a TI-83+

The processor is definately 15MHz.

The light turns on when the calculator is powered through USB.
It's:
- red when the battery is charging
- green when the battery is fully charged
I don't know about the PTT mode as I didn't get that App with the calculator.

Hello, After a first flance at our new TI-84 Plus C Silver Edition in a previous news, you may have expected the software test ? Well, no, there would ave been so many things to say and to test on the OS if we want to make something good, that you'll have to wait a little bit, and meanwhile, here's a hardware test ;-)  The motherboard reveals an architecture based around 2 main chips, very usual on the latest TI-82 Stats, TI-83 Plus et TI-84: - the ASIC
- The Flash ROM memory
As supposed, the Flash ROM memory is a MX29LV320ETTI-70G from MXIO, with a capacity of 4MB ! Once the OS installed, 3.5MB of archive memory is coherent. The size of the OS would be similar to the 84+'s one. We have already met this manufacturer recently with the external Flash-NOR chip in the prototype TI-Nspire Color.But the most important with a historical evolution, it's the ASIC, the chip that contains the processor and the RAM!  Nothing comes to mind ? Let's clean its surface:  The ASIC chip is TI-REF 84PLUSB/TA3! :~o We are talking about the 4x36 ping ASIC chip that equips the TI-84 Plus with HW rev. G and below, as explained in a previous news, and that featured 128KB of RAM! On the TI-84 Plus with HW rev. H and later, which is the majority of them right now and those on the 84 Pocket, TI used an ASIC called TI-84PLCR/TA1, smaller with 4x25 pins, but which only featured 48KB of RAM. :(   Even if it hasn't been tested yet, we can bet on having 128KB of RAM for the TI-84 Plus C Silver Edition, and a 15MHz z80 processor. Having 128KB of RAM is a great news for resources-hungry apps developers (which will be even more with the color....) The use of the same ASIC chip that on the old 84+ is probably a very good omen for the updates of actual TI-z80 emulators Let's just hope that the supposed 15MHz will be enough to handle a display color depth of 8 or 16-bits, requiring 4 to 8 times more processing power on screen output operations.
But for the 128KB of RAM, a big thanks to TI which not only proved listening its users asking for it for years, but also by making, I think, an ambitious choice towards the future, opening the gates to a number of community programs and applications that will make this model a success !Source:http://tiplanet.org/forum/viewtopic.php?t=11268&lang=en

 This might look like, to you, a TI-84 Plus cover ? But actually, tonight, that cover hides your dreams' calculator, the latest member of the TI-Z80 family: the new TI-84 Plus Color Silver Edition !  The time has now come to discover every aspect of this treasure!     Let's see the backside:  The calculator shows a large "Marketing" sticker. Right below, no list of patent numbers, but the Patent pending mention instead, indicating that patents relevant to this model are still pending at the time the device was manufactured. Instead of the classic battery removable cover is a cover locked by two screws. Indeed, a rechargeable battery has replaced the non-rechargeable batteries!   The rechargeable battery is a 3.7L0800SP, which is contained in the cheap rechargeable batteries of the chinese TI-Nspire CM. It packs 800 mAh under 3.7V, i.e. 2.96 Wh. The rechargeable battery is therefore fully compatible with the Nspire series', and should the need arise, could be replaced by the CX or Touchpad rechargeable batteries, for higher duration. Also noticeable is the first appearance in the TI-Z80 series of a 'reset' button on the back. Users are accustomed to remove a battery in order to perform a reset; of course, on this model, no joy. Unplugging the rechargeable battery requires unscrewing, because as mentioned above, the cover has screws. It's therefore pretty logical that a 'reset' button appears, TI thought about it! Let's have a glance at the serial number:  The "K-1212" letters behind the serial number indicate that this calculator was recently manufactured in the K (China) factory, in December 2012. Actually, besides minor modifications, the TI-84 Plus C Silver Edition's cover is based on the TI-84 Plus cover. It's therefore no wonder that we can use it with existing TI-84 PLus stands   On the top side of the calculator, the usual 84+ connectivity: mini-jack serial port, mini-USB plug:  On the calculator's sides, at the bottom, we can see a couple metal contacts:   They're suitable for charging bays, for instance in classroom environments, when one has multiple calculators of the same model  On the top right side, there's another small difference from the original 84+ cover. It's a LED indicating the battery charging process, lighting up when the calculator is connected to a powered USB host:  On the bottom, the keyboard's faceplate is removable, just like on the 84+ Silver Edition:   The 84+ C Silver Edition therefore has the same customization possibilities as the 84+ Silver Edition!   In other words, a great model that we're very eager to boot up for you, in the next episode! Source:http://tiplanet.org/forum/viewtopic.php?t=11266

Thanks for the news and the links DJ_O - I'm quite busy this week-end. Two more TI-84 Plus C Silver Edition news today, but not yet translated into english: http://tiplanet.org/forum/viewtopic.php?t=11276 (about the colors and TI-Basic)http://tiplanet.org/forum/viewtopic.php?t=11278 (about a math bug fix I reported in 2008)In TI-Basic you can draw in 15 different colors on the graph screen:   Color 0 (in asm) on the graph screen is transparency for displaying the background, which is assumed to be encoded in 256 colors - but you won't be able to control this directly from a TI-Basic program. Let's sum up things - the graph screen has: - a 16 colors foreground you can deal with in TI-Basic - a 256 colors background you cannot deal with in TI-Basic

Pictures vars are archived automatically upon creation, yes. DJ_O, could you please duplicate the 1st TI-Planet news link with in source or reference section at the end of your news? Could you please add a link to the 2nd TI-Planet news about the TI-84C hardware too? http://tiplanet.org/forum/viewtopic.php?f=41&t=11268Both content are going to be available in english soon. In this latest news, you got the answer to your questions about the hardware. Very goog news: TI didn't use a new ASIC, but the old TA3 ASIC from TI-84 Plus hardware revision G and older!  Meaning that the 128KB RAM are back at last!

In a previous news, we discovered the launch of a new black TI-82 STATS in Germany for back to school 2012. Let's have a quick look at the TI-82 STATS history: - For back to school 2001 the latest TI-83 adopts a 'Parcus' case and is equipped with ROM 1.10001.
- For back to school 2004, you get the blue TI-82 STATS. From both software and hardware points of view, it's a basic TI-83. The ROM is still the 1.10001. Presumably this name was chosen in order to keep a "TI-82" model, as they were quite popular.
- For back to school 2006, the blue TI-82 STATS disappears in France while still being available in other countries, and is replaced by a purple TI-82 Stats.fr. The latter has a keyboard in French and runs a new basic TI-83 ROM translated into french, the 1.11fr7. But from the hardware point of view, it's a TI-83 Plus motherboard, modified to run only basic 256KB TI-83 ROMs. Known hardware revisions vary from E to G.
- For back to school 2009, the purple TI-82 Stats.fr is replaced by a black TI-82 Stats.fr. It keeps the same ROM version 1.11fr7, and the same modified TI-83 Plus hardware revision G.
- For back to school 2009 again, you get in France the TI-76.fr. It comes with a basic french TI-83 ROM, 1.00fr5, which combines features from the TI-83 and the TI-73. It still uses the previous modified TI-83 Plus hardware.
Despite the similarities of the motherboards, it has never been possible up to date to turn a TI-82 Stats.fr or TI-76.fr into a TI-83 Plus, unlike what is possible with the Casio fx-9750Gii which can be turned into an fx-9860Gii. The difference is that we've never been able to access any boot code on the TI-82 Stats.fr and TI-76.fr. But after seeing this, a new TI-83 Plus.fr using TI-84 Plus hardware wouldn't be surprising... So for back to school 2012, TI-Germany offers us a new black TI-82 STATS, and here is it allready for you! It comes with 4 AAA batteries, the manual, the warranty card and the calculator link cable. The serial number on the back shows us the hardware revision G. It can be assumed that it will be the same modified TI-83 Plus hardware as for the TI-82 Stats.fr and TI-76.fr, a hardware which then wouldn't have changed since 2009.It's exactly the same 'Parcus case reused since 2001, and the color design is the same one as on the back TI-82 Stats.fr, except that the keys are of course in english this time. The memory chip seems to be 32K, and there is no mention of archive memory. It would therefore still be a basic TI-83 ROM.Let's check the last two assumptions by opening the beast: The electronic circuit is organized around two chips: - ASIC REF TI TI-738X, with processor and RAM, which is the chip powering the TI-83 Plus and TI-73, reused for the TI-82 Stats.fr and TI-76.fr
- 512KB Flash ROM chip EN29LV400AT-70TCP from cFeon, with the same capacity as the TI-83 Plus and TI-73
It is therefore exactly the same modified TI-83 Plus hardware than on the TI-82 Stats.fr and TI-76.fr. Now to the ROM: It is a basic TI-83 1.11 ROM, in english of course this time, a ROM version which was unknown to us until now, and we now understand a little better where the ROM 1.11fr7 from the TI-82 Stats.fr did come from. Like other TI-82 STATS ROMs, it can be used on TI-z80 emulators in basic TI-83 mode. On the real TI-82 STATS hardware, this ROM only allows you read-only access to the first 256KB of the 512KB Flash ROM chip. It would seem odd for the TI-82 STATS to suddenly skip several years of development like this. So, I think that the blue TI-82 STATS sold out of France from 2009 underwent exactly the same hardware / software modifications than the ones introduced by the TI-82 Stats.fr. It just remained undiscovered until now because the TI-82 STATS is not available in all countries, and because it usually don't interest the TI community enthousiasts Got a TI-82 STATS with hardware revision A to D? Please reply and help us completing the history of this strange model. Source:http://tiplanet.org/forum/viewtopic.php?t=11215&lang=en

EDIT :
Got this from TI : "The App has been temporarily pulled this morning due to a security issue in the final build. We are working to get it fixed, but we don’t have an ETA on when it will be back up for download – might be a few days. It was just pulled in the past 30 minutes."
There was a way to install Ndless 3.1 ?
