So I bought a used DSL today and when I was buying it I tested it and it works fine with normal games; however, when I got home and tried it with my R4 and Acekard 2i it wouldn't recognize either. Anyone have an idea of what is going on? The DSL appears to have had its case replaced but like I said it runs actual games just fine so I'm not sure why it isn't recognizing the flash carts.
