Pros:

• Since this is an open source, it is free for all and anyone can add or customize games of their choice
• This is a great comeback for the games we used to love
• No need for joysticks to enjoy those retro games
• A wide variety of retro games are available

Cons:

• The graphics seem a little bit outdated. It is still like playing a retro game during the medieval period
• The interface itself is not that user-friendly.
