Game Boy Camera running on a Game Gear with a custom adapter!! This is such impressive work @un_toxa

Meet the Game Boy Camera to Game Gear adapter v.1.0. It was primarily made for the Game Boy Camera, but also works with the other Game Boy carts, which is handy for the homebrew projects. Despite the few errors i made in the PCB design, IT WORKS!!!

As part of some work I've been doing to help optimise a @GBStudioDev project I've put together this tool that other people might find useful codepen.io/roastb/pen/XJbyOW… it lets you drop in background pngs and it merges similar tiles + creates a common tileset image

In latest dev builds of GBS if scenes share a common tileset that include all their combined tiles (like the files this tool generates) then the tile data is only stored in ROM once. So you can set all your rooms in a dungeon to share one lot of tile data. Great for big projects!

Thanks for sharing your project with me @RepugnantBounty. This will be a long thread but I've got some suggestions for you :-)

Only four of these seven dungeons can stay. Which three are you cutting? Please let me know in the comments, preferably in order from favourite to least favourite. #gbstudio #gameboy #Zelda #ZELDATWT #rpg #8bit #RETROGAMING I'm not happy about this decision either, fyi.

Been testing out GodotBoy this morning, a project for @godotengine that lets you drop in your @GBStudioDev game and export a native exe for Windows/Mac/Linux. Seems like this could a good way for anyone looking to distribute in the different app stores greenf0x.itch.io/godotboy-te…

Working on some tools to help diagnose slowdown in @GBStudioDev games. Can scrub through recordings and see what was running each frame. Found a few easy wins for optimisation for the next release! Code at github.com/chrismaltby/gbvm-… if anyone might find it useful (plugin devs?)

Looking at hosting an official @GBStudioDev plugin repository. Does anyone know what happens if you go over the bandwidth limits on @github Pages? Using Netlify for the site but gets expensive some months, want to make sure I can provide this for the community without big costs

The @GBStudioDev build process now runs on a separate thread meaning the UI should stay responsive even during long builds 🥳
GB Studio (@GBStudioDev) profile pictureGB Studio@GBStudioDev9 Sep 2024
Just released GB Studio 4.1.2, another bug fix release. This time addressing issues where building large projects could freeze the app, and fixing the inconsistent pauses that would appear in multi part dialogue boxes chrismaltby.itch.io/gb-studi… patreon.com/gbstudiodev
