I have gotten PI Play up and running, loaded a ROM and it will start in the NES box on the main GUI page. I just cannot get a controller aspect figured out. I have been through the forums and including the GITHUB section on config files for the different supported controllers. I have a Sabrent 12 button controller (model - usb-gamekit). It says it is mame capable, but I am just not seeing it. I noticed that in the folder for controllers, they have json files, but the github one are config files. I will say in advance I am greatly appreciative of any help. I also threw in this link to my controller for any more info (http://www.walmart.com/ip/Sabrent-12-Button-USB-2.0-PC-Game-Controller-2pk/35273253). Thanks.
