I got an arcade motherboard SNK Neo Geo MV1-C last year and also purchased a 161 in 1 MVS multigame cartridge from China. I thought it would be a quick afternoon of work to wire the motherboard to a joypad and a SCART cable in order to set it up. But I ran into a lot of trouble with the setup were I could not get a good display output on my TV from the system.
