This will certainly make optimizing the GB Studio (/BB Studio) engine a lot more fun! :)
Working on some tools to help diagnose slowdown in @gbstudio.dev games. Can scrub through recordings and see what was running each frame. Already found a few easy wins for optimisation coming to the next release! Code up at github.com/chrismaltby/... if anyone might find it useful (plugin devs?)

#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.

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... 🤔

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! :)

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 ;)

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 :)
