How emulators worked before QEMU

I first heard of QEMU around 2006. I was into computer architecture from my early days, and most emulators at the time would simply naively translate instructions from into the emulated architecture at runtime.

QEMU, on the other hand, employed a “Tiny Code Generator” to translate instructions through JIT compilation. It wasn’t as fast as running natively, but for a variety of applications it was fast enough and for many use cases it felt like pure miracle. QEMU also had its own emulation for common physical devices you would expect to find, its own disk image format, and much more.
