Great site of classic Atari 2600 and some original Nintendo games emulated! Some games though are difficult to play using the computer's keyboard keys, and will almost require the investment of a joystick for your computer. One game in particular Megamania runs slow on my Windows 8.1 laptop. Sounds are also funny for that game. Seems to be fine on Windows 10. Games using IE 11 may not have sound. No problems using Firefox No problems with other games running Windows 10 on my desktop. The site is safe to visit and these games can bring back a lot of memories of playing the classic video games of the early 80's.
