Some technical behind-the-scenes about how we maintain our software projects and make sure they remain maintainable

AAntonio Vivace@avivace4 · Apr 10

CI/CD pipelines may pose a big risk (complexity and vendor lock-in), especially for OSS projects. How do you make sure they remain maintainable and agnostic? #devops #devex avivace.com/posts/agnostic…

RGBDS 0.9.2 released! It adds some new features, including more string functions in RGBASM and an excludable "background" color in RGBGFX; fixes some bugs (particularly with RGBGFX); and makes some things more convenient. github.com/gbdev/rgbds/re…

gbdev0's tweet card. May the 4th be with you! ⭐ 👾 Added New 0-indexed string functions (we plan to eventually deprecate the old 1-indexed ones): STRFIND and STRRFIND: like STRIN and STRRIN STRCHAR: like CHARSUB STRSL...

Worked on the Overworld map today, as it was admittedly one of the least developed aspects of the Chantey demo for GBCompo. Here's a comparison video of what's changed: #gameboy #gbstudio #homebrew #indiedev

I finally released the first version of the "Pico GB Printer" game boy printer emulator, which you can use with your PC or iPhone. In first place it is intended to work with Photo! - the Game Boy Camera custom ROM, but should also support any other game. github.com/untoxa/pico-gb…

Red wasps don't shoot and don't eat cake, but they will come after you to sting you. 🫢 Spiders don't eat cake either, but they are fast and once they land on the ground, you can only dodge them. 🤔 #gameboy #gbdev #GBC #Nintendo kickstarter.com/projects/85431…
