Flawless lag free graphics and gameplay for most if not all arcade video games.Quick and easy controller set up for your arcade stick needs.Makes intalling ROM's of classic video game arcades a breeze.After that session, I knew I was going to enjoy most of my other ROM games that I had installed and was extremely excited to play more. Thanks to this version I was able to not even notice till the extremely demanding sections of the game, and even then it didn't really affect my performance or decision making in the game. With other Arcade simulators, I notice right away the lag, and even though this product is not 100% perfect it is 99.9% perfect for me and I am an extremely picky and serious lag hater. The first game I loaded up was my favorite and a classic 'The Simpsons', I got my wife to join up and we didn't put down the controller for hours almost beating the game in one run. Right out of the gate with my controller set up I knew that things were going in the right direction. Man, where do I start with MAME, lately it has been super easy for me to use other arcade machine emulators instead of MAME but I decided to take a leap of faith with this installment and it has been paying off for me so far.
