I think v86 is loading hard disk sectors on-demand, which is pretty amazing compared to Em-DOSBox which has to download a massive disk image. On the other hand, Em-DOSBox has sound support!<p>The Internet Archive has 3.11 in the browser: <a href="https:&#x2F;&#x2F;archive.org&#x2F;details&#x2F;win3_stock" rel="nofollow">https:&#x2F;&#x2F;archive.org&#x2F;details&#x2F;win3_stock</a> (there&#x27;s also various 3.x games as well)<p>This also uses Em-DOSBox.
