After the exhaustive list of May 2025 projects, June is much more subdued: some combination of end-of-semester projects and exams, plus summer vacation and travel, have greatly reduced the number of projects that progressed last month. It's still great to see the projects that did move forward, so without further ado:
- 3D Minecraft for TI-84 Plus CE!: In June, TimmyTurner62 "completely remade" this C language interpretation of Minecraft for the TI-84 Plus CE, which he has been creating alongside ChatGPT. It's a pre-alpha version, but the speed continues to improve: share your encouragement (and your 3D rendering reference books) in the topic!
- Crossword: Potchkee announced that they have finished a Casio Prizm (fx-CG) crossword program that they started several month ago. It has its own format for storing crosswords, but was looking for an open source for crosswords to feed into the program. If you have a suggestion of such a dabase, please let Potchkee know in the topic.
- Graph3CE: 3D Graphing for the TI-84 Plus CE: After a lull of several months, KermMartian completed and published his 3D graphing tool for the TI-84 Plus CE. This application adds the missing 3D graphing functionality that the TI-84 Plus CE lacks: multiple equations, customizable colors/axes/bounds, tracing, etc. It uses a modified version of Cemetechian AHelper's gCAS2 CAS engine in place of the slower TI-OS EOS, and with the help of users, Kerm has already identified improvements to make for the next version, such as support for implicit multiplication.
- KiloFight: StephenM challenges himself to make a Lua beat-em-up style game in less than 1KB, and succeeded - the current version is 1,003 bytes. You fight a series of 20 enemies, but you can only take five hits before you succumb to your wounds, so play cautiously! Give it a try and share your feedback with StephenM, or if you have Lua tips to compress the nearly highly optimized source code even further, let him know!
- Mario Bros. Arcade CE: Last month, we showed an impressive Mario Bros Arcade port to the TI-84 Plus CE by lannoene. They worked hard in the intervening month, fixing bugs, adding features, developing a local multiplayer mode, and adding 11 new levels to the 20 existing levels. You can download the beta on their Github page, and be sure to share your feedback, kudos, and bug reports in the topic.
- Quickzoom: the best graph zooming utility out there for TI-89/T: twisted_nematic57 has been on a roll with a series of utilities and Quality-of-Life tools for the 68k calculators like the TI-89. This month, they released a new improvement for the graphing feature of the TI-89 and TI-89 Titanium calculator, where you can use a pannable, resizable box to choose an area of a graphed function on which you want to zoom in. It also lets you easily back up to previous graph bounds, and has nine slots to store specific window settings for quick recall. TI might tout the intuitive dragging and zooming of graphs on the TI-Nspire, but now your TI-89's graphs can be just as easy to navigate.
- Radioactive Wastes for HP Prime - update v2.00 (multilingual): Ten years ago, komame wrote their first game for the HP Prime in the calculator's built-in PPL language. It was a great first project, but komame acknowledges that as their first HP Prime programming project, it had plenty of opportunities for optimization and improvement. A decade later, komame has optimized it, turned it into an aplpication, translated it to 8 languages, and more. In this 2D arcade-style game, you remotely operate a bulldozer as you try to clear the map of radioactive waste, through 30 increasingly challenging levels. This looks to be a must-have for your HP Prime: grab it in the topic, and share your accolades.
- Space Invaders for TI-83+: Monado07 is trying their hand at an always popular subject for relatively new community programmers: Space Invaders. Monado07 has been learning z80 assembly for the past four months, and after making Pong and Snake (two other excellent self-teaching opportunities!) is moving on to a more graphically challenging project. It's still very much a work-in-progress, but we look forward to seeing their steps forward, and if you have any great z80 ASM tips, tricks, and tutorials, don't hesitate to chime in.
- Sudoku CE: Cars and Ice Cream has shared that since the school year ended, they have translated 75 Sudoku puzzles to this TI-84 Plus CE Sudoku engine, and will be releasing them soon.
- Train Simulator Controller: KermMartian posted yet another update on his elaborate physical Train Simulator controller (think complex flight simulator rig), this time adding a UK-style train horn control to the system. As always, he shares photos and technical details summarized from his blog, so if you're enthusiastic about hardware hacking or trains, check it out!
- TXTADV: a text adventure engine for the TI-84+CE: EYETEADISH is writing a text-based adventure game engine in the TI-84 Plus CE's ICE programming language. The engine can currently handle rooms, items, and custom commands, but EYETEADISH is aware that as the engine expands, they may need to re-write it for speed and space. Screenshots are still on their way, but in the meantime, if you have written a similar engine, or have an idea for a text-based adventure game that their engine could make possible, post in the topic!
