We're back with another round of projects, with June bringing no shortage of fantastic work by our members. Let's check them out:

• Arcade quartet: New to the site, paulvern brought us a collection of original games for the TI-83 Premium CE. It features various battle and puzzle games, including a galaga-inspired game called Star Swarm.
  
• Axe4Unity - Run Axe programs in the Unity game engine.: Created by builderboy2005, Axe4Unity is a compiler and execution environment to run Ti83/84+ Calculator Axe programs within the Unity game engine. There are already several classic calculator games you can play right here in your browser, so check it out!
  
• Bad Apple on the CE, with TI-BASIC: Using Lua Scripts, StephenM created an adaptation of the bad apple video on the TI-84+ CE homescreen.
  
• BASIC Tetris [CSE, 8xp, 83p, 73p, EVO]: tifreak8x returns to his long-time BASIC Tetris game, releasing a version for the new TI-84 Evo.
  
• CosmoCE: A Cosmodread-based roguelike for the TI-84CE: Cemetech member DaniNyaaa made progress on the main character and various other things for their new roguelike.
  
• Ecological cell automata/agent-based simulator for the CE, need playtesters: Puffycosmo has announced the completion of their new ecosystem simulator, complete with plants behaving like cellular automata, and animals like agents. The goal of the player is to create a stable system. Be sure to take a look!
  
• Hexes Hex Editor: StephenM has announced they are working on a full rewrite of their Hex Editor for the TI-84+ CE, moving away from ICE and instead writing it in C.
  
• Hollow Knight on the TI-84 Plus CE-T: New to the site, finnooo8 has begun work on recreating the Hornet boss fight from Hollow Knight.
• Love Me A Raycaster Engine: Written in Lua + Löve2D, StephenM has continued work on their Raycaster engine, this month adding more sprites, a scrolling skybox, and color shaded floors and ceilings.
  
• lwIP | TCP/IP Networking for the TI-84+ CE: ACagliano made an incredible amount of progress, bug fixes, and more. Long-time Cemetechian calc84maniac also contributed optimizations (including a 10x speed improvement in one component) and additions. By the end of June, ACagliano released version 1.2, available in the attached topic.
• Watch grass grow simulator: Mcdonalds_lover_32 has made a incremental clicker game about cutting grass. They're looking for feedback, so feel free to try it and post your feedback in the topic.
• Neon, a new programming language for the CE: Bobb2 presented an interpreted, cross-platform programming language that they have been working on for four years. Neon runs on Windows, Linux, and the TI-84 Plus CE and other ez80 calculators: its design choices are similar to Python's, it sounds like it has preemptive multithreading, and its execution speed compares favorably to TI-BASIC and MicroPython (especially for graphics tasks). Check it out in the topic!
  
• Pixel8, a monochrome sprite editor: Sprite editors have re-entered the zeitgeist, and spiCE_456 has brought Pixel8,an on-calculator sprite editor for the monochrome TI-83/TI-84 Plus family of calculators written in Axe Parser. It's specifically designed for 8x8 sprites for now, and including loading and saving sprites, filling the entire sprite with a color, and inverting the sprite. You can peek at the future by grabbing the July release of the program in the topic.
• Random Things: StephenM has been using this topic to centralize the smaller projects he has worked on that aren't substantial enough for their own topics. In June, he showed off two TI-BASIC creations: a Plot-based 3D-ish racing game, and an on-calculator version of an animation from Deltarune Chapter 4.
  
• RPG Starter Kit CE & Evo: After a long hiatus, tifreak8x has embraced TI-84 Evo programming this summer, including a port of his RPG Starter Kit project. In June, he got the Evo port up to parity with the TI-84 Plus CE version, including supporting a slightly larger map view, full hit detection on map items, screen transitions, and more. He also debugged some features, including scrolling the map. Finally, he helpfully found some bugs in SourceCoder 3's TI-84 Evo support along the way. If you're interested in making an RPG in TI-BASIC for the TI-84 Evo, check out RPG Starter Kit!
  
• Screen Receiver for Casio CG calculators: Cemetech newcomer scratching_claws is building a Casio Prizm (fx-CG20, fx-CG50, etc.) screen receiver program, using some modern browsers' WebUSB API. They were inspired to create this by the official Casio program for Windows not having a Chromebook port: if you have a Prizm and want to be able to take screenshots of your calculator or share your screen in class, check out scratching_claws's work!
• SNAKE++: Continuing their resurrection of an almost five-year-old project, RedSpacePanda released v1.0.0 of their TI-84 Plus CE Snake game this month. it includes snazzy graphics (and a Classic mode), a store for upgrades like custom skins and apples, and a customizable UI. If you're looking for a great Snake game for your TI-84 Plus CE, give this one a try!
  
• SRec-Dump-App: An Impractical, Yet Useful, ROM Dumper: CVSoft has been productively lurking in the community ever since their more active years, and has resurfaced on the forum with a ROM dumper for the TI-73, TI-73 Explorer, and TI-83 Plus. CVSoft was motivated by an interest in archiving the operating systems/ROMs of very early TI-73 models he and community member Adriweb have collected for historical reference. He performed some of his testing on the TI-83 Plus (same z80 processor as the TI-73 family), culminating in a ROM dumper that dumps data at about 400bps in Motorola S-Record format, yielding successfully dumped ROMs even with one-way communication (i.e., without confirmation, although it does have checksums). If you have an unusual calculator from which you want to save the ROM before its ROM or EEPROM reaches end-of-life, this is a strong contender (and may be your only option)!
• Tari's opportunistic Z80 computer: Tari has been working for about a year on a z80 computer, prompted by a fortunate find of a z80-based single-board computer (SBC) in a scrap pile. In June, Tari debugged the hardware (namely the PCBs he has designed and fabricated for the project), did a bit of bodge wire-based rework to resolve bugs, then made a snazzy aquarium-esque case for the project that shows off its card-based design. Follow along in the topic for Tari's hopefully upcoming updates!
  
• TI-84 Evo projects: In addition to his RPG Start Kit earlier in this list, tifreak8x shared a list of the other TI-84 Evo projects he has been working on and has released: BTetris (TI-BASIC Tetris), Checkers, Connect 4, and Charz (a character table program to insert special symbols in TI-BASIC programs and strings). He also shared his ongoing and upcoming projects: the RPG Starter Kit, an ABBA Caving Calculator (it's a Minecraft thing - join our server at mc.cemetech.net!), Age of Darkness (to be built using the RPG Starter Kit), Hex2Sprite, and a 2048 game. If you have encouragement, feedback, or suggestions for other projects tifreak8x could work on, post in his topic!
• TI-84 Plus CE FTP client with lwIP-CE: Never far from an ambitious low-level project, this month TIny_Hacker released an on-calculator TI-84 Plus CE FTP client built on ACagliano's TI-84 Plus CE lwIP port. This IP stack makes it simpler to build network-connected apps on the TI-84 Plus CE family that don't require any external computer program or complex hardware, just a USB-to-Ethernet adapter and an Ethernet cable, and this FTP client is a great example. It lets you connect to a server by IP with a username and password, then transfer .8xp and .8xv (program and Appvar) files between the server and your calculator. If you want to grab and back up files to and from your calculator without a computer, you now can!
  
• WebTILP: a web version of TILP - now available in v1 (beta): Adriweb (and Codex) have been working hard on a web port of the respected TILP linking program this year. In June, Codex added support for the RS-232 (serial) GrayLink cable using the WebSerial API, and Adriweb and CVSoft immediately were able to use this for CVSoft's ROM dumper linked earlier in the thread. If you want to connect your computer to a wide variety of calculators using a similarly broad supported set of cables, and don't want to (or can't) install software on your computer, WebTILP is a great solution.
  

And that's it for June! Be sure to vote for your favorite completed project in the poll!
