I have a DSP 0501 controller (looks exactly like the RZNC-0501, but it must be a clone. I accidentally loaded the RZNC firmware and now the hand controller is hung at a "Piracy Control" screen. I honestly didn't know that it wasn't an RZNC controller, they look identical. The only numbers I have to go by are "SQNC-0501HDDC -L07-100088". If anyone out there has firmware that will work with this controller, please help!
