My first QEMU patches were applied on April 23 in 2006.
I'm the maintainer of those parts of QEMU which are needed to run it on the Windows family of operating systems. Windows is a registered trademark of Microsoft Corporation in the United States and other countries.
I'm also the maintainer of the TCG interpreter (TCI).
Please send any patches to the qemu-devel mailing list and cc to me. Add "w32" to the subject if the patch is for the 32 bit version of Windows, "w64" if it is for the 64 bit version, or "tci" if it is for the TCG interpreter.
