This will certainly make optimizing the GB Studio (/BB Studio) engine a lot more fun! :)

GBDK v4.4.0 is out, and contains several improvements for the NES platform, mainly focused on improved GB compatibility. highlights: * VBL/LCD ISR handlers use GB conventions and pseudo-registers * Timer interrupt emulation allows improved music playback * Tilemap functions wrap around correctly

#gbdk (and #bbstudio) is getting new NES tilemap layouts! By default we use 1-screen layout for simplicity - but this has scrolling artifacts. The NES can do better. 2kB VRAM allows H / V layout to limit artifacts. And cartridges can also provide VRAM for 4-screen layout to remove them completely

This Kickstarter marks the very first two physical NES games making use of gbdk-nes - the NES backend of gbdk-2020 which powers a good deal of the BB Studio engine. These two puzzle games will have a physical space on my shelf... as well as a fuzzy feeling inside. #gbdk-2020 #nesdev #retrogaming

Cool tool, and works with BB Studio builds! Now just have to figure out why the GBC sample project got bumped to 512kB when there only appears to be 16 total banks in the ROM... 🤔

Stunning NES level design from @vinikdev.bsky.social ! Having grown up on Knightlore and other isometric Speccy games I really look forward to moving around in isometric spaces made with BB Studio... :D #nesdev #gbstudio #retrogaming

Mistakes happen. And the second BB Studio alpha had two bugs with palette switching and number comparisons in scripts. If either of those were affecting you, download this new hotfix! And if they weren't... download it anyway! :) github.com/michel-iwani... #gbstudio #nesdev #retrogaming

Happy Belated New Year! ...and Happy Belated New BB Studio version! Still just an alpha, but this new version fixes some crucial usability issues in the first alpha release. Check out the comment section for full list of fixes! #gbstudio #nesdev #retrogaming github.com/michel-iwani...

On top of various bug fixes and usability improvements, BB Studio will soon have a dedicated NES color picker. So no more of that RGB conversion guesswork! (...just the inevitable Never-The-Same-Color guesswork from the golden years of gaming ;) #gbstudio #nesdev #retrogaming

Thanks for reporting bugs on the BB Studio github. They are slowly being looked at, and an improved alpha should be out this month. For quicker fixes, remember that the github automated builds may already have a fix for an issue you're having :) #gbstudio #nesdev #retrogaming

GB Studio is an amazing tool for making real Game Boy games. But what if Big Brother NES wants to play too? Now there's BB Studio - a hacked version of GB Studio, to run your GBS games on the GB's Big Brother! NOW YOU'RE PLAYING WITH WALL POWER. #gbstudio #nesdev #retrogaming

Two siblings, the Nintendo Entertainment System and the Nintendo Game Boy, having a good game together.
