This isn't specific to Capcom games as the boards are obviously different and I believe Capcom pulses much faster but the general troubleshooting steps are still the same. First though make sure you don't have a bad socket or set of sockets that's creating a short. And make sure they are no LEDs installed unless you have the OCD board too. Good luck!!
