gametop.com Honestly not sure how safe it is, I get those random virus alerts but nothing seems to affect my mac. Most viruses dont affect macs though so who knows if it's safe on windows. Plus i have no good anti virus except free avira version so could be undetected So just be careful ! Gametop does seem good though for sure
theisozone is good for some older games like Crimson Skies and Sonic Heroes. It's basically games half-way to becoming abandonware, but not quite yet.
