Just-about...! :D I thought you'd ported Armagetron for a moment. Good game! As for me,
I'd say there's at least an 80% chance my OS GUIs will end up with a lot of black surfaces and glowing neon lines. ;)

It has console. It has calculator and clock. But what's most important…
It runs DOOM!

Another windowing system implemented in-kernel... tsk tsk!

But seriously, congrats on the Doom port!

Yes, I tried recording something knew but VirtualBox refused to let me. I'll try again later.

My suggestion is to use OBS to screen-cap VirtualBox or QEMU - that's how I do all my videos these days. I found VirtualBox's integrated video recording to have weird stutter issues.

Wait, you got Quake to run?! If the Github page is accurate, you started in September last year. I'd say that this is really impressive, if that's the case.

:D I've ported SDL 1.2 (video, events, threads and partially timers and audio). Since quite a lot of games use SDL, porting them requires just some minor tweaks.

Your next step should be to port Bochs, so you can run your OS in your OS.

Haha… What have you done?! OSception? Good job!
That would be funny if I could do that as well. But not happening right now. I still have some issues with writing on ext2 (which is the only writeable filesystem on my OS for now).
And I thought about actually trying DOSBox. But first BusyBox, YASM and GCC (binutils are already done).

What is OBS? Are you referring to "OBS studio"? Trying to find it, but can't.

Yes. It’s typically just OBS in conversation, there’s nothing really special about Studio over the previous version. It’s the gold standard in desktop recording and streaming these days.

After taking a 5 month break I decided to pick quack back up. I have started moving it to a microkernel architecture, and so far I've got:
  • New and improved scheduling and task management code
  • A simple exec server that can start new programs from ELF files passed to it via an IPC message
  • A way for processes to handle device interrupts(process sleeps until the interrupt arrives, kernel wakes the process up)
  • A test program that handles PS/2 keyboard interrupts and simply prints characters to the screen
  • Other stuff too small to mention individually

Anyway, here's an image of what I have going on right now:
Image

In this picture the "hello world, this is quack" text was typed in via the PS/2 keyboard, and the one lone character at the bottom is the least significant byte of the global system tick counter, which processes can nicely ask the kernel to map into their address space as read-only. All I really need to do now is to actually focus on the userspace side of the OS, since the kernel has almost everything I need(apart from waiting for multiple kinds of events, like waiting for either an IPC message or an IRQ).

Nothing impressive or of the other world, has no paging, multitasking, or executables files yet. (well, sincerely I have no idea how to do it, but well ... :( ) At least it's something more than a simple bootloader that just prints "Hello world". :)
Only haves an 80x25 screen resolution, text only. Who needs GUI? A simple shell is enough for everyone! You can have a fancy OS with beautiful GUI, but the kernel can be buggy, or not fully functional. (there are exceptions) Or you can have a ugly shell, but a fully functional kernel.

Now CHicago have it's own assembler + linker for the userspace, with a custom executable format.

All the non-efi stuff (except the loaders) are written for my OS. Now just to find the framebuffer, load the driver and kernel files, and set up virtual memory.
