EDIT: Current version attached to this post.

Hi everyone !

You may have heard about one of my best programs, the RPG Herssahe, in several versions for each calculator model.
The version 4.2 (full Basic) is still one of the best graphicals RPGs for TI-82 Stats/TI-83.

A bit later, but I was still a young child, I made the 5th version of Herssahe with Xlib, when Axe and Grammer did not exist yet
But now, I think it is too old, crap, and I wanted to make a great program with Grammer

So I announce the sixth version, made with Grammer, with grayscale graphics

Notable changes (in project ) from the 5th version:

• better AI in battles
• better names of items, attacks and spells
• items to retrieve and a true SCENARIO  
  
• Grayscale and abuse of the particles to make beautiful graphics and animations
• Cheatcodes  :P and maybe texturepacks :)
• weight halved

Please give me all your ideas, especially if you know stylish names for attacks, I have 9 different attacks to name and no imagination

Thank you !!

Progress of the program: 12%
The program ZDATA will be compressed when I will have finished to draw all the sprites I need, don't worry.

Yes, sorry. Critor thought it was a "School Property" model, the first time he has seen it. It's a regular model, but painted.

Yeah, like Sauron

Yes. Excuse me.

Except the fact that this anti-downgrade protection "surprised" us by coming on a "rare" 3.2.4 and not on 3.6 as expected, granted.

I think that what hapened with portuguese exams made emergency to block nlaunch. The OS 3.6 is not ready yet, so, it's a fast reaction step.

OS 3.2.4. It is not available yet on Texas Instruments' website, but the latest TI-Nspire CX made ​​come with a new OS, the 3.2.4.1237 (source).

The TI-OSes include an "anti-downgrade" protection, a minimal installable OS version that they write in the NAND memory between the Boot2 and the Diags, an inaccessible area to different official reset procedures.

When installing, the OS 3.1.0.392 increases this minimum version to 3.0.2.1785 if the number was lower.
Similarly, the OSes 3.2.0/3.2.2/3.2.3 increase it to 3.1.0.392.

It officially becomes impossible to reinstall an OS version prior to the programmed number.
In practice, it was possible via two methods:

• using a Ndless utility reprogramming itself this version number
• using the nLaunch OS-pitcher who installs and launches the OS completely ignoring that version number

According to  a report this morning on TI-Planet, it seems that the OS 3.2.4.1237 greatly increases the minimum number of installable version that ... to a value which now refuses to install any previous OS to date, including OS 3.1, 3.2.0 or even 3.2.3!  D:

Therefore, if your new TI-Nspire comes with OS 3.2.4 or if you update your calculator with this OS, it officially becomes impossible for you to use Ndless because requiring the OS 3.1 and this just a few days of the exams. :(

The added bonus, the CAS-engine bugs introduced with OS 3.2 and not present on the OS 3.1 such as roots quotients are still here, and the prohibition to return to a version with CAS that worked better is simply incomprehensible from the point of view of users, even just a few days of the exams.

But does it remains always possible to override the anti-downgrade protection with nLaunch?

The OS 3.2.4 contains as added bonus a new version of the boot2: 3.2.4.4 against 3.1.0.16 since the OS 3.1.0.392.

nLaunch exploited a flaw in the boot2 3.1.0.16, and you can bet, I think, that it has been corrected.

Therefore it also becomes officially impossible to use nLaunch and number of legitimate applications like:

• make cohabit the OS 3.1 and 3.2 on the same calculator to enjoy the best of both worlds with both Ndless programs (3.1) and Lua programs (3.2)
  
• Launch a Linux OS

It can be assumed that this OS 3.2.4.1237 is a response to the recent use of TI-Nspire CX launching TI-Nspire CX CAS OSes to the Portuguese exams that prohibit CAS, possibility that allows nLaunch although this has never been the goal of the authors (not mentioned in the ReadMe).

The only feasible and untested bypass to date would be the reprogramming of the boot2 3.1.0.16 via a TTL / USB adapter (called RS232) to connect to the Dock of the TI-Nspire:

So we especially recommend you to not update your calculator to OS 3.2.4, if ever it appeared in the coming days.

And if you already have a TI-Nspire CX with OS 3.2.4, to date you must certainly not erase it. Indeed, as it is not available on TI's website and as all existing OS are rejected, you will find yourself with a calculator without any OS usable! Again, a few days of the exams, it is not very smart ...  ::)

Thank you anyway, but no

We should reproduce this feature on a z80...

Hello,

I am using this code found on TI-Calc to solve equations and inequalities 

It works very well... excepted that it always ends on an error NO SIGN CHNG, which means that the solve command cannot found another solution.

When you study how this program works, you can see that it always searches for 4 solutions to any equation, and gives the error if there is less than 4 solutions...

To prevent the error, is there any mean to know how many solutions the equation have  ?
If I could know it at the begining of the program, I could forbid it to search for more solutions... and give errors.

Thank you for your help...
