Super Mario Kart requires a missing DSP rom in order to work. I have located the rom information but in order to make it work, they must be combined. I have been unable to locate a way to combine them. I am guessing that ClrMamePro might be able to do this but have not found anything to help. rom name="dsp1b.u3" size="10240" crc="2838f9f5" needs to be added to the smkart file but the files that make the dsp1b rom are dsp1b-program.bin dsp1b-data.bin. When combined they will correct the missing rom. Can someone advise how to combine these two files into dsp1b.u3?
