The March Projects of the Month showcase is here at last: better late than never, right? March was another busy month at Cemetech, with progress made on games, utilities, hardware projects, and even a Google Sheets-based simulator. Here are March 2026's Projects of the Month:

• Befunge Interpreter for the Ti83+ line of calculators: Jeff calc 84 is working on a Befunge-93 interpreter for the TI-83+ line of calculators, written in Axe, along with a Python-based converter script to turn .bf source files into calculator appvars. In March, Jeff calc 84 added three example programs and continued development toward getting complex programs like Hunt the Wumpus running on the interpreter.
• BloxorzCE: StephenM is porting the classic Flash puzzle game Bloxorz to the TI-84 Plus CE, in which players roll a rectangular block through a series of stages to reach the exit. The project was announced in March with all core mechanics fully implemented; during the month, StephenM focused on recreating all 33 levels and adding visual polish, hopefully with a release coming soon. If you enjoyed playing Bloxorz in your browser, check out the topic and share your positive encouragement with the author!
  
• Building The Aperture Science Computer Case in 2026: TheLastMillennial is building a PC case modeled after the iconic Aperture Science computers from the Portal game series, complete with 3D-printed panels, laser-cut stencil for painting, and careful cable routing. In March, TheLastMillennial announced the project and got it nearly to the finish line. In addition to teaching themself just enough CAD to be dangerous, TheLastMillennial designed and printed the extra pieces that convert a rectangular case into the curved shape of the prototype, painted the Aperture logo, and created their own housing for the I/O ports. Keep your eyes open for the finishing touches in April!
  
• CE Font-Via-Localization Hook: Iambian's CE Font-Via-Localization Hook allows users to install custom fonts on the TI-84 Plus CE by making use of the calculator's localization hook, and includes a companion utility for reading and writing font files from TI-BASIC. In March, Iambian restructured the code repository and updated documentation, then focused on the computer-side tool for building a font, including both PC and Mac versions.
  
• Crates 3D (TI-84 Plus CE): JamesV is porting the classic TI-83 puzzle game Crates 3D by Badja to the TI-84 Plus CE, with upgraded color graphics taking advantage of the CE's improved display. In March, JamesV added some graphics polish, completed the port, and released version 1.0.0 to the Cemetech archives, featuring 16 levels. Grab it from the topic, try it out, and be sure to share your props and feedback.
  
• Express BASIC - a Tiny BASIC interpreter in C: lucidapogee is developing Express BASIC, a cross-platform Tiny BASIC interpreter written in C with editions for DOS, Windows, and Linux, aimed at providing a syntax more standardized than other Tiny BASIC dialects. In March, lucidapogee added port access for DOS (only), as well as additional example programs (bringing the total sample games included to 18!). Later in the month, they corrected negation in arithmetic expressions, fixed bugs, then announced a major upcoming update: graphics support is returning and will now be cross-platform. In addition, and particularly relevant to Cemetech, graphing commands are being added to make the interpreter function as a programmable graphing calculator on any supported machine.
  
• Geometry Dash port for 83/84+: RubiGEX is working on an Axe-based port of Geometry Dash for the monochrome TI-83/84+ calculators, inspired by the lack of such a port for the older calculator line. The project was announced in March, with an animated screenshot of early progress shared, and RubiGEX noting plans to expand the game as they learn more Axe. If you're a fan of Geometry Dash, stop by the topic and add your encouragement (or Axe expertise)!
  
• Google Sheets Voxel Light Simulation: DragonScholar71 created a voxel light simulation running entirely within Google Sheets, using a Minecraft-inspired algorithm that propagates light by finding the highest adjacent value and subtracting a dropoff rate. The project was shared in March, complete with a public link for anyone to copy and experiment with.
• HD Picture Viewer [C] [TI-84 Plus CE]: TheLastMillennial's long-running HD Picture Viewer for the TI-84 Plus CE supports high-resolution images with zooming, panning, and a wide range of color depths. In March, TheLastMillennial released v3.0.0 Alpha 2, adding long-awaited animated GIF support with performance improvements from calc84maniac's lz4hc compression method, full 16-bit color throughout thanks to Tiny_Hacker and Roccolox's GFX16 library, a fully rewritten converter with native Linux and Mac binaries, and most GIFs now exceeding the 20fps stretch goal.
  
• Love Me A Raycaster Engine: StephenM is developing a raycaster engine in Lua using LÖVE, with configurable resolution, sprite support, and texture mapping. In March, StephenM posted a major rewrite of the engine featuring proper perspective correction, warping negation, the ability to read textures directly from image files, and a per-texture transform function system for creative warping effects - including learning from other Cemetechians' work.
  
• Mr. White: Hallodaddy070 created Mr. White, a social deduction word game (think Mafia, Among Us, or Blood on the Clocktower, but with words) for the fx-CG50 and other MicroPython-compatible calculators, where most of the players know a word, and must say related wors, but one player is an imposter that does not know the word and must avoid detection. During March, Hallodaddy070 released the initial version on Github and quickly followed up with v1.3 and v1.5, the latter adding a new "fool" role that gets a random word, is told either it is an imposter or not, and does not know it has the fool role. He also expanded the word list. You can check it out and provide feedback in the topic!
• My own OS!: Voblit created a small custom operating system called "I Like Flowers OS", written in C# and compiled via a framework called COSMOS down to a bootable .iso. The project was shared in March with screenshots and a GitHub link, with Voblit noting that COSMOS's C# integration made the development process approachable given their prior C# experience. Voblit is considering trying to more closely replicate the Windows 10 Blue Screen of Death in a future version.
• Oiram level creator on the calculator.: Griffon (originally published on TI-Planet) created an on-calculator level editor for the popular Mario-like TI-84 Plus CE game Oiram, allowing players to build their own levels directly on the device. Cemetech member calcgeek created a topic on the author's behalf to ensure Cemetechians saw the project, and also published their own level to demonstrate what the tool can do.
• Pyoro!: mr womp womp created Pyoro!, a full-color TI-84 Plus CE port of the classic Pyoro minigame from WarioWare, Inc.: Mega Microgames!, bringing a game that had previously only existed in grayscale on older calculators to the CE. The game was released in March, complete with a download and GitHub repository. It looks like a beautiful rendition of a fun classic: give it a try, and let mr womp womp know what you think!
  
  
• Raycaster in AXE for TI84+: Znak_Pares wrote a raycaster engine in Axe for the monochrome TI-84+, achieving approximately 8 (later 10) frames per second on hardware. Znak_Pares discovered Axe and wanted to create a raycaster as a proof-of-concept of Axe being faster than TI-BASIC, in which they had previously written a raycaster. They worked fast: by the end of the month they had published an early version of a Wolfenstein 3D-like game to the archives, with further optimizations and texturing. They haven't worked on the project lately, so check it out and give them some encouragement!
  
  
• Sans-sational Font Editor: naga_s is developing Sans-sational, a new TI-84 Plus CE font editor written in TI-BASIC with Celtic CE, designed to provide a cleaner and more feature-rich alternative to Iambian's existing C-based font editor. The project was announced and actively developed throughout March, culminating in a release in mid-March, which includes a clipboard, small and large font editing, font previews, test-driving, and Omnicalc/zStart font import support. The interface is beautiful and pushes the boundaries of what Hybrid TI-BASIC can do on the TI-84 Plus CE: check out the eye-candy and share your feedback with naga_s!
  
  
• Subway surfers on ti 84 plus ce: calcgeek is working on a Subway Surfers clone for the TI-84 Plus CE in C, using the project as a vehicle for learning the C programming language and the CE toolchain. In March, calcgeek continued development, working on sprite display and sharing a new main menu design mid-month. They're following proud Cemetech tradition of using project topics to ask questions and learn, so please keep an eye on the topic in case you have expertise you can contribute!
  
• Terraria CE: slimefolf is working on a Terraria demake/port for the TI-84 Plus CE in C, with a focus on building a chunk-based world engine using fileioc appvars for storage. The project was announced in March, with slimefolf sharing early progress, namely their initial chunk loading and archiving engine, and inviting critique of the fileioc code.
• Thunderbirds v2.0.0: JamesV is reviving their long-dormant Thunderbirds game for the TI-84 Plus CE, a side-scrolling shooter inspired by the classic Amiga game, more than ten years after the original thread was started. In March, JamesV returned to the project and implemented an animated walking sprite for the player character, including adding a lookup table to correct the sprite's foot-planting behavior across animation frames. Hopfeully JamesV gets to work on it again before another 14 years elapse, so go share your encouragement!
  
• TI-89 Titanium Remote Control via ArTICL: hwd2002 created a remote control demo for the TI-89 Titanium using ArTICL, allowing keystrokes to be forwarded to the calculator via a serial console connected to an Arduino, including handling special control characters like backspace. ArTICL support for the TI-89 and other 68k-family calculators is incomplete, so hwd2002's example should serve as helpful reference for other programmers looking to use ArTICL and these calculators together.
• TI-Boy SE Progress Thread: calc84maniac's TI-Boy SE is a Game Boy emulator for the monochrome TI-83 Plus/TI-84 Plus calculators, supporting grayscale rendering, zooming, and optional audio. calc84maniac has been working on the project since 2010; in March, they released Beta 0.2.06, fixing LCD compatibility issues on newer TI-84 Plus models and resolving a hang-on-exit bug on the TI-83 Plus SE when audio is enabled, achieved by switching to a polling method for the LCD driver rather than repeatedly adjusting CPU speed.
• TI-Planet's "Project Builder" with online CE C/C++: Adriweb's TI-Planet Project Builder is an online IDE for developing CE C/C++ programs directly in the browser, with a built-in compiler, toolchain, and collaboration features. In March, Adriweb fixed a session token refresh bug that had been causing users to be unexpectedly logged out, improving session management reliability and modernizing some backend and frontend code. He also expanded the project-sharing features to allow sharing projects as read-write with a few selected users, and allowing everyone else with the link to view the project read-only.
• TinyTurtle: A lightweight Turtle Graphics module for HP Prime: komame's TinyTurtle is a lightweight implementation of Python's turtle graphics module for the HP Prime, offering both real-time drawing and a viewport mode with pan and zoom. In March, komame released v1.00, a near-complete rewrite of the module that grew the codebase to nearly three times its previous size, adding a procedural API, Cohen–Sutherland line clipping for viewport rendering, title bar support, and significantly improved CPython Turtle API compatibility. komame took advantage of fixed-point math instead of expensive floating-point math to accelerate performance-critical sections, redesigned text to use vector instead of bitmap representations for both space and text scaling. It's an impressive program that can produce some beautiful output with a little experience, so if you have an HP Prime, this should become a must-have on your calculator.
  
• WebTILP: a web version of TILP - now available in v1 (beta): Adriweb's WebTILP is a web-based implementation of the TiLP calculator linking program using WebUSB, allowing users to transfer files, take screenshots, and view device info for their calculators directly in a compatible browser. In March, Adriweb pushed bug fixes that resolve light-theme text color display issues and missing translated status text reported by users.
  
• Worms68k Party for TI-89: orokro is reviving their 2004 Worms clone for the TI-89, a near-complete implementation of Worms World Party that was abandoned due to a memory limit bug and then resurrected decades later with AI assistance. In March, orokro officially released the game, publishing it to the Cemetech archives and a dedicated project homepage with a post-mortem write-up, noting they were unable to do further polish due to time constraints but declaring the long-anticipated project complete. We're thrilled to see so many long-unfinished projects getting more love this month: we encourage you to go compliment orokro for finally finishing and publishing this project, and of course to download it and try it out.
  
• Zero ZGC4 Emulation in QEMU: TIny_Hacker (alongside RoccoLox Programs) is adding emulation support for the Zero ZGC4 calculator to QEMU, reverse-engineering the hardware peripherals and writing machine support code along the way. In March, TIny_Hacker released a set of flash-tools scripts to simplify emulator setup, including a script to generate a usable internal flash image from Zero's v2.25.0 flasher update file, and another to copy a file into the emulated calculator's filesystem. If you have a Zero ZGC4 and want to be able to develop programs for it more easily, this is a great tool for your toolset.
