GB Studio 4.2.0 Beta
Thanks for your patience, it has taken longer than I originally planned, but GB Studio 4.2.0 is finally ready for beta testing.
You can download the beta right now at https://github.com/chrismaltby/gb-studio/releases/tag/v4.2.0-beta1
This release is mainly aimed at plugin authors, giving them a chance to test existing plugins, make any required updates, and maybe even submit them to the new plugin repository (more on that later!). While major changes aren’t expected before the final release, this is still a beta, so please remember to back up your projects before trying it.
There’s lots to cover in this version, too much to write here but here’s some of the highlights:
Improved scene types
The Platformer scene type now includes most features previously provided by hauntology's Platformer Plus plugin. That includes dashing, double jumps, coyote time, wall jumps, solid actors and more. All these features can be toggled on or off as needed, and disabled features have no performance impact. If your current project heavily depends on Platformer Plus, migration not be easy, it might be best to stick with older GB Studio versions until you start your next project.

The Adventure scene type now also supports solid actors as well as rounded corner collision tiles to make it easier to walk into tight spaces.
The Shoot ‘Em Up game type now includes more configurable options such as Free Movement so you’re no longer locked to one screen edge.
You can also now toggle individual scene types on or off per project. For example, if you’re making a platformer, you can set Platformer as the default for new scenes and hide other scene types so their settings and events don’t even appear.
Plugin System
There is now an inbuilt plugin manager allowing quickly finding, installing and updating from an approved list of plugins.

If you are a plugin author who wants to add your plugin to the official repository you can submit a PR to https://github.com/gb-studio-dev/gb-studio-plugins
And More
- Support for per project constant values
- Sprite editor quality of life improvements
- Linux ARM (Raspberry Pi) support
- Camera backtracking and bounds control
- Per scene 8x8px sprite tile mode support
- Extract color palettes from background images
- Rate limit event to handle things like only being able to fire X times per second
- Automatic tile flipping in Color Only scenes to reduce ROM usage.
- “Run From Here” scene preview, by right clicking on a scene. Allows only including selected scenes for faster build times.
- Per scene color mode override allowing a game to have Color Only sections
- Lots of bug fixes!

As always if you spot any problems, please make sure to report an issue at https://github.com/chrismaltby/gb-studio/issues
Thanks to everyone who contributed to help build this version and an especially big thanks to all the subscribers on Patreon who helped make this release possible.
Hope you all enjoy the holiday season! I’m aiming for this to be the official release here on Itch.io early in the New Year, I just need to write the documentation now!!
Thanks,
Chris

OKAY WOW. The scene improvements were very needed, platformer is now able to have metroidvania games now with double jumps. Adventure is now better for sure. And this doesnt even include major things? These scene type changes are huge already (actually im not sure if you did mention scene types as major or not). One problem ive been having though is that my game wont stay saved after turning off my anolouge pocket. I use an sd card that i put game onto into AP. Also maybe the double jump and other things like that could be an event too to turn on or off for an unlocking mechanic
You're such a legend... I've downloaded it and started making stuff straight away! One question: I see there is a Knockback state in settings. I've already added my knockback animation state, but I don't know what event to use in the scenes in order to activate the knockback state... am I being dumb?
Of course you're not being dumb. Seeking advice from others is always a smart thing to do.
I'd help you if I could, but I'm just as clueless as you.
thank you.
Thanks for the update! The improvements to the Adventure type scene would be beneficial for the Racing game I’m working on!
Huge. *_*
Thanks for the update!
is this version complete?
I think I still might wait to try this engine again, but congrats on the new release!
Very cool! Very tempted to buy a gba to try out the engine lol
Do it!
THANK YOU! I love GB Studio so much.
Thank you for all the work you've put into making this awesome piece of software!
