@bombers821 it is illegal to sell retropie especially with roms already included. 3rd party images are not supported here. If you would like support here you will need to download the official supported image (https://retropie.org.uk/download/). If you want support for you're current image you'll need to ask the person who sold it to you for help.

You're probably looking for Netplay.

@Crimsøn64 Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

Provide more details and a log after launching game.

@mumihp did you managed to solve your problem?
