In case people here might not have kept up to date with calculator releases outside CodeWalrus, here are some notable ones that I spotted in the last two months:
Vecx (TI-Nspire) https://tiplanet.org/forum/viewtopic.php?f=20&t=16484&p=186422#p186422
-Basically a Vectrex emulator for the TI-Nspire. That console from the 80's had a CRT screen attached to it and featured monochrome graphics, but vector-based instead of pixel-based, so the resolution was quite high. The emulator supports the plastic filters (similar to the ones from the Mangavox Odyssey) that we could place on the top of the Vectrex screen to have colors.
Tail-Tale (TI-Nspire) https://www.omnimaga.org/ti-nspire-projects/sdl-ports-for-nspire/msg401798/#msg401798
-A puzzle game similar to Tetris Attack for the SNES.
Code Zombie (TI-84+CSE) http://www.ticalc.org/archives/files/fileinfo/465/46500.html
-A zombie apocalypse shooting game where you must keep the economy alive, by buying low and selling high, while killing every zombie on your path.
Falling Time (TI-Nspire) http://www.ticalc.org/archives/files/fileinfo/465/46507.html
-Falldown on steroids. It is a port from an GCW Zero game.
Lolicopocalypse (TI-Nspire) https://www.omnimaga.org/ti-nspire-projects/sdl-ports-for-nspire/msg401732/#msg401732
-Warning: This platform game might contain NSFW content, although it is implicit, not explicit. It looks extremely interesting to play and has a very old-school feel, though.
C programming on the TI-84+CE! https://www.cemetech.net/forum/viewtopic.php?t=11626
-Ok, this one is actually from late May, but I thought I would mention it anyway since it was posted after my previous news: Basically, with the help of MateoConLechuga, C is now possible on the TI-84 Plus CE and the TI-83 Premium CE calculators! You need Zilog Developer Studios II to use that language. He posted a tutorial on how to set up your C environment in the link above.
