Halfix is a portable x86 emulator originally written in C99, but this fork was ported to C++20. It allows you to run legacy operating systems on modern platforms.
This fork is used to test lib86cpu, a cpu dynamic recompiler library.
This fork is focused only on Windows compatibility for now. You will need a C++20 compatible compiler, zlib, cmake and Visual Studio 2022. Only 64 bit builds are supported.
cdto the directory of halfixmkdir build && cd buildcmake .. -G "Visual Studio 17 2022" -A x64 -Thost=x64- Build the resulting solution file halfix.sln with Visual Studio

Currently, when used with the Boch's BIOS and the LGPL'ed VGA BIOS, it can boot the Windows XP installation CD up to the point where Windows tries to set up the FPU.
Create a directory with all the files you want to transfer and create an ISO image.
mkisofs -o programs.iso -max-iso9660-filenames -iso-level 4 programs/
Now update the configuration file as follows:
# Note: it does not hae to be ata0-slave.
# I have not tested it with anything but ata0-slave.
[ata0-slave]
inserted=1
type=cd
file=/tmp/programs.iso
driver=sync
Now boot up your operating system and copy the files from the CD-ROM to the hard drive.
