Yes, I should write about v86's internals some day. Meanwhile, the code is right here: https://github.com/copy/v86/tree/master/src/rust It's much faster with recompilation than without, bu

If you're bored (or your code is still compiling), you can also try: SerenityOS: http://copy.sh/v86/?profile=serenity (one of their developers contributed PAE support to v86, which is extra cool. I believe it cont

v86 also recompiles machine code to web assembly. The main difference is that v86 is a hobby project (of which I'm the original author, by the way), with much fewer contributors and no (known) commercial users, and is much less sophist

It's a fully emulated PC: CPU, memory, hard drive, … The CPU especially took me very long to get right with all the details to run Windows 98. The code is here: https://github.com/copy/v86

The project is made with both browser and nodejs support in mind. There are still some issues to resolve, but I will definitely release a node version this year.

Hi s-macke. I've read the source code of your emulator before, good job. I'm aware of the problem with big integers. I'll look into this more closely, thanks for your help. Regarding workers: I need some restructuring to get

It should be the US keyboard layout, because that's what the operating systems in the emulator use.

I got Freedos working about 2 years ago, but then stopped working on it. I picked it up again earlier this year. Approximately 3 months of full time work. I'm considering writing some articles, just need to find some free time.

Yes, it's very similar to the jslinux project. However, I added more hardware (it can boot a real bios: seabios). Also, I'll make this open source.

It expects one of the standard formats (720k, 1440k or 2880k). I'll add switching disks some time in the future.

I'll put it online soon. I haven't figured licensing out yet and need to write some technical notes
