Thanks for the link. I have tried to connect to it over WIFI and can not do so. It seems that the recalbox can't connect to my wifi. I know my usb dongle works, as I have used it with RPi2 before. The SSID for my network has an underscore in it, would this be an issue?

Hi everyone. I have been scanning the internet and these forums for a solution that I can understand but can't seem to find one. My experience with Raspberry Pi and Linux is very limited, so please keep that in mind. Is there a way to drag-and-drop ROM files into a folder from the SD card or a way to transfer them via USB to the SD card? I can't seem to figure it out. Using v3.3.0. I have all other items setup and configured the controls for GPIO pinout. I am building an arcade cabinet and it was supposed to be a Christmas present, but I am not sure I am going to make it on time if I can't figure out how to put ROMs on the system. Any help is much appreciated. Thanks
