Dear visitors and members, with the staff having moved on to other life interests and as a result of changes in people's internet usage habits, the CodeWalrus community have migrated almost entirely to Discord, IRC and WalrusIRC and is now essentially a place where to hang out, chat about gaming, programming, music, anime, and chill. As a result, even though the CW forums will remain open for posting, for faster TI, Casio or HP calculator help and news we recommend using the bilingual TI-Planet forums instead.

We encourage everyone to join our Discord server now.

We were supposed to announce this last week, but the TI-Connect and Ndless news delayed it, but we are pleased to introduce a new forum feature: Topic tags!

Basically, in your topic title, if you put some text inside brackets ([TI-BASIC], for example), it will now be converted into a color tag that can be clicked. Clicking the tag will allow you to quickly search the forums for similar topics! It also draws attention more so if, for example, your project is for the TI-84 Plus, then putting [TI-84 Plus] in the topic title will attract people seeking for TI-84 Plus projects.

It has some limitations, however: Currently this feature doesn't work in the Recent Posts page and blocks since the mod doesn't take SimplePortal into account. Hopefully one of our tech-savy staff member can help modifying the Recent Post blocks to fix that. It is also currently impossible to sort topics by tag, which is something we would like to implement in the future. But it should make it easier to find certain topics. Thanks to WadaNon for this mod!

In addition to this new feature, the board rules were slightly modified tonight, now including "disruptive behavior" as a disallowed thing in Rule #4. As always, we encourage our users to make CodeWalrus a friendly place to hang out and showcase your creations. :)

Also, the last update is about our staff. Streetwalrus lacks the necessary computer access to fullfill his CodeWalrus duties and to remain active on a regular basis. As a result, his activity will remain sporadic until school vacations.

An extra sub-forum called Safe-haven was also added several days ago, after the off-topic ones. It is restricted to only certain group of users or regular members above a certain post count, though, and is restricted to only certain type of discussions (real-life-related, for example). You can request an invitate by going to Profile->Group Membership then clicking "Request membership" next to the "Safe-haven access" usergroup.

As always, if you have any suggestions, concerns or questions then don't hesitate to post them in the CodeWalrus discussion section! We want to make sure that our members are happy about the website, the team and what we do so let your voice be heard. :)

Calculators in General
So a while ago, TI Connect CE 5.0 was released by TI as a compliment to the TI 84 Plus CE. Since it has new features, including a program editor, I have decided to do a full review. Sadly, this software only works with z80 USB-port models, but you can have TI-Connect 4.0 installed alongside it, so you are only really missing out on the new features.

First up: Start Up
Immediately after the splash screen splashes, you are greeted with the basic interface in screen capture mode. There are three modes, easily accessible from the sidebar, including Screen Capture, Calculator Explorer, and Program Editor. To the immediate right is the connected calculator list if you are in Screen Capture or Calculator Explorer mode, and the tokens list if you are in Program Editor mode. When it is the connected calculator list, you can switch between connected calculators quickly. Just click the one you want to switch to, and you're ready to go!

The Screen Capture Mode at Startup
Screen Capture
The Screen Capture mode is just an interface change on the one from TI-Connect 4.0. You can only take screenshots from the confines of the TI-OS level. This means you can't take screenshots from flashapps or assembly programs. Kind of a bummer, but nothing new. The interface does feel sleeker and more modern, but I feel TI could have updated the feature for this software.

Calculator Explorer and File Transfer
Since this is connectivity software, this is the most important part of this package. How is the connectivity? In a word: fast. It takes very little time from drag-and-drop of programs to menu, and the actual transfer takes full advantage of the USB capability. You also have the option to send files to all connected calculators, which is very nice, especially if you are working on a multi-player game and want to improve the time it takes to get the files to both calculators. In the Calculator Explorer itself, you see everything on the calculator in the sleek interface, and can switch between calculators easily. You can also double click a non-protected, non-assembly program to edit it within the Program Editor almost instantly, which leads nicely into the next section.

File Transfer Menu
Program Editor
TI has not released a program editor with their standard link software since TI Graph Link. This program editor is a nice addition to the software, once again with a sleek and modern interface. It features a tokens list and reference on the side, and can send the program to a connected calculator with the click of a button. The editor feels a lot like TokenIDE or SourceCoder, but with different syntax for store arrows and superscripts and such. The copy-paste issues from Graph Link have been fixed, though, so the store arrows (→) and the like show up properly when pasted into posts. The only language supported is TI-Basic, as is expected, since this is TI's product and not the community's.

Program Editor

Overall, this is a nice update to TI-Connect, and you will enjoy the new file transfer speed and the TI-Basic program editing, as well as the new interface. Although the screen capture is still lacking, it is still the best TI Connect to date.

Notable Game and Software Releases
If, for whatever reasons, you are stuck on TI-Nspire OS 3.9.0 or 3.9.1 (such as school forcing you to upgrade or your calculator revision being Hardware S or higher, which didn't work with OSes older than 3.9.1), but still want to use Ndless, then good news: It's out! :D

For those who are unfamiliar with the TI-Nspire, Ndless is a tool that allows the calculator to run C, Python, Javascript and ARM assembly language softwares created by members of the TI community. Normally, the calculator comes built-in with support for both Lua and a limited form of TI-BASIC. ASM and C programs get more control on the calculator, allowing them to run much faster, so you can play games such as DOOM, Quake, Crafti (3D Minecraft clone) and run Nintendo games via various console emulators. In addition to that, you can watch videos and get access to more powerful educational tools such as Khicas and nPDF!

With Texas Instruments devoting between 0.001 and 100% of their profits into locking down their newest TI-Nspire OSes to prevent third-party native programs from running, it usually took over 6 months after a new OS release before new exploits can be both discovered and used to use Ndless on them. Version 3.9 comes out earlier than expected and runs on OS 3.9.0 and 3.9.1. After five years, despite TI's actions, the Ndless team has never gave up, never let anyone down nor deserted us, even if they had every reason possible to do so.

If you still use OS 3.1, then you will have to use Ndless 3.1 instead, though, and OS 3.6 will still require Ndless 3.6.

It is also discouraged to use Ndless 3.9 on TI-Nspire Clickpad models, because they do not have enough RAM to run both OS 3.9 and most Ndless programs simultaneously (only 2-3 MB of RAM left). Also, Ndless 3.9 will not work on Touchpad (grayscale) models.

In addition to that, users of Nspire CX models that have hardware revision J or higher, as well as those who don't use Nlaunchy, should probably stick to Ndless 3.6. Without nLaunchy nor an OS that can run it, Ndless 3.9, which uses the same exploit as DowngradeFix 3.9, requires computer access in order to be re-installed following a calculator crash or reboot. You can still use Ndless 3.9.1 regardless, but under such conditions it won't be ideal.

Notable Game and Software Releases
TI has just released TI-Connect CE 5.0 on their official website. It is a standalone version of TI-Connect that supports the USB version of the TI-83 Plus.Fr, the TI-83 Premium CE and the entire TI-84 Plus family. It sports a brand new interface, which lets you edit calculator program code most notably, and offers considerable improvements on file transfer speed. While it used to take 30 seconds in the original TI-Connect to initiate a transfer at all, everything such as drag-n-dropping a file in a Windows folder is now instant.

Unfortunately, this version of TI-Connect drops support for serial linking and consequently, support for the TI-82, TI-83, TI-83 Plus, the original TI-83 Plus.Fr, the TI-83 Plus Silver Edition, TI-85 and TI-86 was dropped. Also, all 68K models including the TI-89 Titanium are no longer supported. On the other hand, TI-Connect CE acts as a separate entity from TI-Connect 4.0, so installation is done in a separate folder, meaning it will still let you use both.
