Well guys days , forgive my English is not my native language. Some time ago I discovered thanks to the retropie and could make my own arcade machine when finished recreational all my friends and family wanted to make him and the other did. Later they got friends of friends asking me for more machines compatible with retropie and encouraged me to sell , after a having doubts whether it was a good idea and decided to do it and last one year. I wanted to thank the retropie project and all the guys on the forum for your help.
