QEMU is 15 this year
From: https://www.winehq.org/pipermail/wine-devel/2003-March/015577.html
Hi, The first release of the QEMU x86 emulator is available at http://bellard.org/qemu/. QEMU achieves a fast user space Linux x86 emulation on x86 and PowerPC Linux hosts by using dynamic translation. Its main goal is to be able to run the Wine project on non-x86 architectures. Fabrice.
