Recently I have been working on a TCP stack, an HTTP client, and a Clang/LLVM Port. There are still a few bugs (e.g. clang provides ld with an empty object file, called ld myself) and there is no HTTPS support (yet, had to upload file myself as github redirects to https), however here is a screenshot of Lemon OS downloading klange's nyancat, building it and running it.

He's done the thing very few have experienced:
...completion of Bare Bones 2!

Hi guys,

Sorry I haven't been around lately to help answer questions. I have been busy with other things.

However, I have had a little time to work on my project.

Image

The image above is Win10, running QEMU, running FYSOS, running FYSOS' 32-bit (un)real-mode emulator, running DOS v5.0, running "Wing Commander".
i.e:
Code:
Win10  (Host development machine)
   \-->  QEMU  (main emulator)
              \--> FYSOS   (my little OS project)
                        \-->  FYSOS' 32-bit (un)real-mode emulator
                                    \-->  DOS 5.0
                                                \-->  Wing Commander

Six levels of 'OSness'...

I even wrote up a 'test suite' to compare each instruction used with other emulators. It doesn't actually test the instructions, it simply executes them and prints the state of the machine after the instruction (regs and flags). I then can compare these results with the same 'test suite' ran on, for example, Bochs, and see where my emulator failed. The test needs work, much more detailed tests, but so far has caught a nasty IDIV bug, as well as a few others.

Ben

That's nice! DOS must run slow being nested so much. Either way, that's a big feat!
I have thought about writing an x86 emulator myself. Then I got interested in C++ and game engines, and decided to work on that instead of my OS for some time :)

I wrote the first game for Cyjon, a Tetris clone :)

Nice screenshots everyone, felt a bit nostalgic to see a thread I started 15 years ago still receive replies. 8)
