QEMU is still amazing even without KVM; KVM is just a performance improvement for native platforms. But with QEMU you can emulate extremely exotic CPUs on stan

  Not to trivialize QEMU (I use it often and I love it) but usually the challenge with console emulators are A) emulating supporting hardware such as graphics chips which are often undocumented and B) achieving cycle accurate emulation for platforms which need that. QEMU emulates relatively standard hardware for each platform. Even for x86, sometimes I find 86box or PCem more desirable for certain older hardware/software vs QEMU.

    Well, it depends, the i440FX chipset with an SB16 will run most if not all DOS games.

      ... and, since you need the OS, there's always FreeDOS.
