Various existing games, such as This is the Only Level, Androides, Billybox, Mandragore, Bejeweled, Flappy Bird, Pac-Man and Pac-Attack, were also ported to TI calculators by our users and various retro gaming console emulators (SNES, Turbografx-16, Sega Genesis, Master System, etc) were released for the TI-Nspire CX.

Aside from game development, our participating forum users have released notable tools such as ICE Compiler, Houstontracker 2, CEmu, the C SDK and Libraries for the CE. We also have our share of musicians and pixel artists as well, along with a massive database of MTV Music Generator series songs from the remains of TIMGUL. A lot of new projects are also active in the development section, ranging from new games to programming utilities and 3D engines, so expect new releases at any moment.

With that lame-duck year at my old work place being almost over, I am announcing that I am returning to staff at 4:45 PM. I will be part of the moderator and forum maintenance group.

We will also have two new staff in the near future.

Since we will have at least one moderator again, we would also like to remind members to not use the forums and chatroom while under the influence of alcohol and drugs or without receiving proper treatment for any disability unless they are 100% guaranteed to remain in full control of themselves . Each user is responsible for what happens with their user account.

Well, look like we have a few issues with the MySQL server once in a while around when the backup script runs, we're investigating the issue and we'll keep you updated. Sorry for the disruptions!

Notable Game and Software Releases
Linux is coming to the Prime.
It should have been there a long time; the chip it runs on, the S3C2416, has been supported for a long time. Recently gaining access to tools for jtag, I decided I would go and connect things up, not realizing that the newer revision of Prime didn't even have jatag pins broken out on the front of the board. I bought a prime, and started working.

Tonight, I got up and running with a shell. There's nothing else here but the shell, actually, and many things don't work. But I got the LCD and serial port working, which is easily enough to test with.

Here's a picture of the shell up and running on tty0:


The sources can be found on my github:
linux
ripem build with loader
qemu for Prime
Since I don't have a good setup for the initramfs running right now, I'm going to figure out how to get buildroot up and running. As long as I'm not too busy with school, I'll figure out how to make a keyboard driver and get the rest of the theoretically working platform drivers (usb, touchscreen) working. If anyone wants to help, go ahead!

An update on CodeWalrus' status and upcoming changes:


-Based on Juju's life schedule and mine (all of which is explained in two topics located in the access-restricted safe-haven sub-forum), CodeWalrus has most likely been saved at this point.

-No matter if things in Juju's life go haywire or not, the Discord, Telegram and IRC channels are here to stay.

-We are switching to PhpBB 3.2 software. This is our final weeks as a SMF 2.0 website.

-We will also attempt to merge the TIMGUL archives into CodeWalrus database, but it is not 100% guaranteed (a temporary conversion to MyBB is necessary).

-The new website will only replace the current one once Juju got OmnomIRC or WalrusIRC to work on it. (most likely OmnomIRC for multi-channel support)

-The new website will only replace the current one once Juju made sure that the current CodeWalrus topic URLs are still working (either via redirect or read-only archive).

-The old SMF CW website will remain fully browsable in read-only mode for posterity, but file attachments, as well as very large files (such as the arcade content) will only remain available on the PhpBB site for disk space reason.

-Work on the new website will begin somewhere around August 25th, where I will gain SSH and PhpMyAdmin access under @Juju 's supervision.

-All CodeWalrus features that are exclusive to SMF plugins have 99.99% chances to be reset, permanently lost or read-only during the PhpBB conversion, such as the following:
 *Topic cloning (the ability to place one topic in multiple categories at once, which only staff could use)
 *Post rating, karma and rating reasons
 *Custom profile fields (Ticalc.org, Skype, calcs owned, etc). You will have to manually copy their content one by one from the archived SMF CW website onto the PhpBB one.
 *The list of all front-page news posted before the upgrade. It will be archived in a topic.
 *Publicly-visible board statistics (posts per day, Juju stat graph, site traffic, top members, etc)
 *Other things I might have forgotten.
 
-There is no exact timetable about when exactly the new website will go live. While the bulk of the upgrade will happen during a short timeframe at the end of August up to early September, the rest will be slow, as work on the new website can only happen while me and juju are online at the same time for extended periods of time.


More information will become available as the upgrade process begins, but feel free to ask here or in this forum section, as we will not bite any member for being curious.

Calculators in General
Bad news for students who are planning to purchase a brand new TI-84 Plus CE for this upcoming school semester: If you planned to play Oiram CE, Calcuzap, Wal-Rush! CE or First Fantasy on your calculator, then you might be out of luck.

Last Spring, Texas Instruments introduced the 13th hardware revision for the TI-84 Plus CE model, ending with the letter I. Unfortunately this change breaks compatibility with many a few ASM and C program and games released by the TI community over the last two years, causing the keypad to no longer respond during execution, forcing you to hit the reset button on the back. And what makes this worse is that there is no way to tell if the calculator you will buy (new or used) is gonna be hardware I or later or if it's gonna be an older one that can run those games.

For now, there is no estimate about when (or if) a C SDK libraries update that circumvents this issue is gonna be released, if it's even possible at all, because none of the TI community developers own such recent TI-84 Plus CE version. The TI-83 Premium CE is also affected.

In April 2007, a similar situation affected the TI-84 Plus and TI-84 Plus Silver Edition with missing RAM pages, while in 2016 it was the TI-Nspire CX's turn with a new LCD hardware. And TI isn't alone, as the fx-CG9860G series changed processor completely in 2011.

Update: Turns out it breaks compatibility with only one way out of many to fetch keyboard inputs, namely interrupts. Fortunately, the only known program that uses them is Oiram CE and some toolchain demos, but still, it is a problem if you're planning to use them in your programs. Mostly every program should work fine on hardware revision I, provided they don't use interrupts. Please check with your program's author if it's affected.
