Welcome to CodeWalrus: A software development community with a focus on retro-gaming, music and pixel art on various mobile platforms, including graphing calculators, as well as game consoles and PC.

Since October 2014, our active members and staff have released several new games for the Sega Dreamcast, Panasonic 3DO, Atari 2600, TI-84 Plus, TI-84 Plus C Silver Edition, TI-84 Plus CE, TI-Nspire CX, HP Prime, Casio fx-9860G, Android phones and computers. This includes First Fantasy: Mana Force, Sorcery of Uvutu, Reuben Quest: Lost Between Times, Oiram CE (a Super Mario clone), SQRXZ CE, KillMinds, VVSSV, Line++, Lazer 2, GalagACE and Wal-Rush!

Aside from game development, our participating forum users have released notable tools such as ICE Compiler, Houstontracker 2, CEmu, the C SDK and Libraries for the CE. We also have our share of musicians and pixel artists as well, along with a massive database of MTV Music Generator series songs from the remains of TIMGUL. A lot of new projects are also active in the development section, ranging from new games to programming utilities and 3D engines, so expect new releases at any moment.

Up until now, we have been approving pretty much every thread that has been submitted to the randomness section, despite our desire to keep its growth controlled. We have decided to start rejecting some threads in there, in an effort to keep the overall quality of the content posted on CW to a reasonable level.
Thanks for your understanding,

Notable Game and Software Releases
Yep. It's a small company based in Montréal and Phoenix who makes a few interesting homebrews for Intellivision/Colecovision/NES/SNES. It's pretty cool.


Also have some gameplay of their game Sydney Hunter & The Sacred Tribe (in French), it looks pretty amazing.

Oh, as a bonus they even bought the rights to the Acclaim and LJN brands. You know that one with the rainbow logo everyone hates? A small homebrew maker from Montréal, Canada bought it. Nice.

Notable Game and Software Releases
Hello! It's been a while since this news editor has written anything, and it's time to change that! Without further ado, let's jump right in to it!

First up, for the Casio Prizm, we'll be discussing Prizoop, a Gameboy/Gameboy color emulator. Developed by community newcomer tswilliamson, it claims to run approximately 95% of Gameboy games at 60 frames per second, with "safe" software overclocking enabled. Sound support, ROM compression, and auto frameskip are new additions in the latest update. The project is open source and the code is available on GitHub for anyone who wants to contribute or just view the code. Planned features include savestates, as well as performance and file footprint improvements.

Second, the long awaited CE port of the ever popular TI-83+ series gameboy emulator, TI-Boy, has been announced, although no downloads or source code are available at this time. TI-Boy CE, by long time community member calc84maniac, appears to be coming along nicely, with a 60 fps video showing off a working version of the program. Planned features include automatic colorization of supported Gameboy games, real time clock emulation, and a configuation saving feature.

As always on CodeWalrus, we do not recommend nor condone the usage of pirated ROMs. That said, if anyone has any Gameboy or Gameboy Color homebrew that they have written or would like to share, feel free to link it below, so long as the site hosting the homebrew does not host any sort of pirated material.

If you wrote some homebrew for the Gameboy or Gameboy Color, feel free to message me a screenshot or gif of it running on one of the featured emulators, or any emulator running on a calculator. You might be featured on a follow up article!

Thanks for reading! See you in the next article!
