We’re clearing up our backlog of Projects of the Month articles, and April 2026 did us no favors with a long list of Cemetech projects that were introduced, released, or at least moved forward. The month also saw the release of the anticipated TI-84 Evo calculator, and this month’s list (and especially future lists) will reflect this.

• 2D Structural Matrix Solver for the TI-Nspire CX: IlTvrco shared StaticaLT, their new 2D structural matrix solver program. The program is written in TI-Lua for the Nspire and sports a GUI, plotting graphical results and a number of other useful features.
• 30 Seconds: Hallodaddy070 published their game "30 Seconds", made with Micropython for the fx-CG50. When playing the game, players have 30 seconds to describe words which their teammates must guess correctly to gain points, with the first team to reach 30 points winning.
• BasicOS: Re-defined: A new Shell for the 84+CE (and some history): Adding to the impressive history of BASIC shells under their belt, naga_s announced a new Hybrid BASIC shell which they expect to be their final shell for the TI-84 Plus CE. The shell supports program execution and a number of file operations, along with plans for utilities (a timer, clocks, stopwatch, and more).
  
  
• Befunge Interpreter for the Ti83+ line of calculators: This month, Jeff calc 84 fixed an issue with the ` (greater than) command in their Befunge interpreter, as well as adding a Sieve of Eratosthenes sample program.
  
• BrainfAX: a BrainFk interpreter made with AXE: Znak_Pares wrote an interpreter for the popular esolang Brainf*** in AXE. The program also includes a built-in editor, as well as a nice interface for program execution allowing the user to view input and output, step through code, and restart the current program.
  
• Building The Aperture Science Computer Case in 2026: Completing a dream project for any portal fan, TheLastMillennial put the finishing touches on their Portal inspired PC case, adding a power indicator and orange RGB fans. They also printed out a number of textures and easter eggs from the original games on sticker paper to spruce up the sides of the case. Check out the forum topic for more cool photos!
  
• A CJK characters text reader on TI84+CE: Ziyang created a CJK characters (a collective term for characters used in Chinese, Japanese, and Korean writing systems) reader for the TI-84 Plus CE, dubbed "CERE". To minimize storage use, the program comes with a Python script to generate the necessary glyphs for the specified source text, avoiding the need for a full CJK font.
  
• DICE4RPG - A flexible BASIC dice roller for color 84PCSE, 84PCE, etc.: nvdaydreamer created a versatile dice rolling program that lets you choose any number of dice to roll, including not just polyhedra (e.g., your standard D6, D8, D20, etc.), but also Fudge/Fate dice (which produce a bell curve rather than a uniform distribution) and Dungeon Crawl Classic (DCC) dice. If you play D&D or other tabletop roleplaying games, and don’t have the space or funds for a big dice collection, this program is for you!
  
• Emulator without a name.: ti_kid began creating a TI-83 Plus/TI-84 Plus emulator for the TI-84 Plus CE, using an existing z80 core. He implemented an emulation layer for port 10 and port 11 (the monochrome calculator LCD ports), and in April worked on debugging his work to date, including sharing the code on Github and getting some feedback from other Cemetechians.
• FamiCalc - an NES emulator for the TI-84 Plus CE: Zaalane has been working on this NES emulator for a little while, refining and improving pre-release versions for community testing. In April, Zaalane released version 0.2.1 in their Github repo, including fixing two bugs (one of which prevented Metal Gear from working) and emulating the Audio Processing Unit (APU) more accurately. If you want to run NES games on your TI-84 Plus CE, check this project out!
• Half-Life 2D Demake: FieryFork is using a tool called bipsi intended for creating “low-fi games to play in the browser” to create a Half-Life-inspired, top-down, 2D puzzle-like game. In April, they were about halfway done with the game, but haven’t posted any updates since, so if this project is up your alley, please share your feedback, ideas, and especially encouragement in the topic.
  
• Half-Life: Supersymmetry (Half-Life 1 Mod): FieryFork apparently is a Half-Life enthusiast: they are also working on a Half-Life 1 mod that takes inspiration from the cliff-side levels of Half-Life 1 and the Citadel levels from Half-Life 2. They want to make the levels feel as real and believable as possible; they have released screenshots and a demo, and estimate they’re about one-third through creating the mod.
  
• Mr. White: Hallodaddy070 continued working on this TI-BASIC social deduction game that we featured in March, releasing version 1.5 with a new role, the Fool. While most players get the same word, and the Imposter gets no word, the Fool gets a random word, and can either be an Imposter or Mr. White: they therefore could appear to be the Imposter although they might not be, and inject some additional confusion and deduction into the game. If you enjoy social deduction games, this one might be for you.
• My isopod hobby website: calcgeek has been taking full advantage of the force-multiplying possibilities of LLM coding assistants, creating a niche website (but who are we to talk?) all about isopods, the segmented creatures also called pillbugs or rolly-polies. They (or their LLM) rapidly added a user system, the ability to track and log isopod colonies, a sticky note system, a karma system, a web-searching function, an in-website chat, a forum, and even an AI bot that can send isopod pictures. If you happen to be an isopod enthusiast, you’ve probably found your new home.
• Myriadas: StephenM announced a 3D space simulation-type game in pure TI-BASIC for the TI-84 Plus CE that they have been working on for almost two years. They have rewritten it from scratch a whopping 6 times, and finally have a version they feel is ready to share with a broader audience. You explore, trade, and combat enemies in an infinite procedurally generated world, to reach the highest rank and become a respected commander. It’s an ambitious work-in-progress; if you like ELITE or other space simulation games, please go encourage StephenM to continue working on this project!
  
• Brand new NES Emulator for the Nspire!: MihkeyMouse09 announced NesNspire, a C++ port of Jay Kumogata's InfoNES emulator for the CX II, this month. Nspire users will be excited to see an NES emulator which supports the newer Nspire models! While the program isn't complete, it's in a usable state and the author is looking for feedback.
  
• Plants Vs. Zombies CE: lannoene shared a faithful Plants Vs. Zombies port for the TI-84 Plus CE that they have been working on. It has 4 levels so far, and the graphics look highly realistic; they point out that more optimization is coming, so for now, make sure you have plenty of free RAM available. It’s in the Cemetech Archives now, so check it out and share your feedback with lannoene!
  
• Pokémon Lavender Version: Cemetech newcomer just_late shared a ROM hack of Pokémon Crystal that they are creating, called Pokémon Lavender, expanding the existing game with a new region to explore, a new story, and lots of quality-of-life fixes. They shared a Github repo, but no released game: if you’re a Pokemon fan, go share your encouragement and comments.
  
• Radix Studio: Liam P is following in a proud Cemetech tradition by making their own esoteric language (esolang) called Radix. It has a well-defined instruction set, and Liam P has created an interpreter and IDE in Python for the language. Check out the example program in the topic, and grab the released IDE from the Cemetech Archives.
• Reverse-engineering and making new levels for Cellar 3D: Voblit is reverse-engineering the popular TI-84 Plus CE game Cellar3D by graphing calculator veteran and all-time most-downloaded ticalc.org author Patrick Davidson, in order to create new levels for it. With the help of other Cemetechians, they have made some progress understanding how levels are structured.
• Introducing: Sheltic CE: CalcNoobie101 is building a hybrid TI-BASIC shell for the TI-84 Plus CE using the Celtic CE library. It allows you to run programs, customize the look-and-feel of the shell, and also adds convenience functions to enable lowercase and invert the colors in the OS. They have ambitious goals for a built-in program editor, settings menu, and other features, so be sure to share your thoughts and feedback in the thread.
  
• SNAKE++: After a four and a half year hiatus, RedSpacePanda has returned to this TI-84 Plus CE project to use sprites instead of blocks of color for the apple and the snake segments, including different snake appearances. They have also shared the list of features that they want to add, and spoiler alert, they squeezed in a version 1.0 release at the end of June that you from the future can go download and play right now.
  
• TI-80 Emulator Web Port: mr womp womp and Adriweb (and AI coding tool Codex) ported Zeroko’s impressive TI-80 emulator into a webpage: you can now use this seminal “lofi” TI graphing calculator without leaving your browser. As required by the license on Zeroko’s emulator, the port is open source, so if you have your own improvements in mind, you’re welcome to fork it!
  
• TI-Planet's "Project Builder" with online CE C/C++: With the release of the TI-84 Evo calculator, Adriweb added support to convert TI-BASIC programs to/from Evo format. They also added support for the human-typeable token equivalents across the TI-83 through TI-84 Evo calculators that tools like SourceCoder and TokenIDE support. Hats off to Adriweb (and his AI) for some excellent reverse-engineering of the TI-84 Evo file formats, and if you want to create TI-84 Evo programs, Project Builder is a great option.
  
• TinyTurtle: A lightweight Turtle Graphics module for HP Prime: komame released version 1.10 of this impressive HP Prime project in April, adding more cursor shapes and the ability to make custom cursors, support for font styles, the stamp() method, and a variety of optimizations and bug fixes. This remains one of the most thoughtful and well-developed projects we have seen for the HP Prime, so if you have this powerful calculator, try it out!
  
• Tyrian CE: conf is working on a port of the game Tyrian to the TI-84 Plus CE. They’re still in the early stages of the project, and are looking for some debugging help, so if you consider yourself a TI-BASIC expert, they could use your assistance.
• Wireless messaging system for TI-84+ using the ESP32-C3 microcontroller: ineedsleep42 wanted to experiment with ArTICL and wireless communication, so they used ArTICL to allow two calculators to communicate wirelessly using two ESP32-C3s. It’s a work-in-progress with only a video for documentation so far: if you’re curious to learn more (for non-cheating purposes), be sure to post in the topic.

As always, we have a great field of completed projects for your judgment and ranking: pick your favorite, and see you in our May Projects of the Month!
