I've never used this, but I just have to say this:
The tooling ecosystem in SB4 is very different from SB3. With subprograms and UIRUN you might want to reconsider your vision for this. It would be really interesting to see some kind of pluggable subprogram with application windows, so you can use it on top of the editor or direct mode. Just being a standalone mock OS would still be cool, but might be a waste of potential. You seem to have done something very impressive and ambitious here, and if you can redirect some effort into something more utilitarian or that integrates with SB4's environment system more directly, it might be even better.
I've just released a public test build of サカキバラUI for o3DSs.
It does have bugs but I just want to listen from you how well it works and feels.
Project key: ＱＤＱ４Ｂ３Ｆ３
I think I'll use this as the build for both o3DS and n3DS.
changes
You are restricted to 10 windows at a time. It's unlikely to have more than 5 windows open, so that's a good sacrifice.
The keyboard is a bit unfinished but is working well rn.
Due to the compressed FONTDEFs, the fade in to the desktop is bad.
The text editor and the MML player are currently unusable.
ミドリOS packages (at least some tests) work fine but some more will be incompatible.
Wow looks pretty slick. Did you design the icons on a computer and scream or hack them over to SB?

Please be honest when voting. This poll will also apply to the Switch edition I'll make soon.
Special things exclusive to the versions are obviously marked.
The 3DS's FS is already made and points to project files.
I'll make apps taking advantage of it any time soon due to the deadline.
What I imagine the Switch FS to be before your impact
I'd have it store data in the FS to prevent leftover files in your project.
I think it's handy to have files for ideas or other stuff in the FS, shared between other projects I think. I'd use that very often.
Well, I made a weird decision and that lead to me releasing サカキバラUI already unpacked.
I've used 12Me21's compression tool to shrink the GRP file sizes, extremely!
FYI サカキバラUI takes ~20 MB of space if you unpacked everything.
Now I managed to shrink it down to 3.5 MB with all files intact, just the GRPs compressed.
I guess I won't need the setup for now. I just need to compress the files before I release the next build.
Sure, this is time-expensive and causes my PC to blackscreen a lot but in the end, it's better since I don't have to worry about Out of memory issues the whole time.
Cool news, what about the update?
Well... IDK really.
I added the FS with some tools I left in the project, including a DOS-like prompt as seperate program.
The explorer has now the ability to read from the FS but not write or spawn other apps to edit the files.
A dev tool named _CYFS-GENERATE will create the FS with pregiven paths and file pointers as DATAs.
Included is a modified Midori OS packet, the 2nd demo, which corrupts opened apps. Now it also corrupts the FS as a test.
I also included the SBS database test program where, depending the project's existance, you can launch other's programs, like Virtual Bufallo, R-OS V, etc.
The settings were updated to include a crued keyboard in the settings section.
Unsuprisingly, a discontinuation note was added, which explains the out of active dev-going. Depending on the 3DS's date, a different message may show up.
Hmm... The editor would look good.
If it doesn't work like that, PM me and then I have to reimagine how the direct mode may look like.
(I'll turn SKKBAUI into the XFCE4 shell, if something like that is possible)
(It´s actually a DAT file but I've extracted the characters, so it's better to see here.)
The session file will take between 32KB and potentially 1MB depending on opened applications and 
Here's an example of the setup. It animates a bit rather than beimg a still image.
Also, another poll (I know it gets old but the Switch version will bring more polls)
Due to the massive amount of files I have:
Should I limit the setup to be more Windows-like?
[poll=p725][/poll]
I first make the sprites high-res and then shrink them down to the size I need.
It's, um, pretty neat, has chroma keying, allows gradients as text-colors and such but one downside it has: it is spamming ads after saving or importing images.
I'd only recommend it if you either stay offline or get a working ad-blocker.
