User kyberias was so kind to port the native part of vamos (the m68k emulation) to Windows and send me his patches for inclusion. The port is now included in my source tree and Windows user can now enjoy using vamos on their platform, too. Have a look at the README.WIN for build instruction.
With Mac OS X and Linux/*nix support available since the beginning, vamos is now available on all major platforms.. Yay!
