on an american retrocade you can add arcade games but on a european retrocade they won't run (they will flash and get you back to the menu). However, you can get them to run by installing a custom firmware. You'll need to put the firmware on a memorycard (in the back of your retrocade) then install the gameroms on a usbstick (in usb port 2). Don't worry, you'll still be able to play in multiplayer by using a usbhub on usb port 1. Here is the link for the firmware : https://gbatemp.net/threads/release-custom-firmware-for-the-super-retrocade.550116/
