Just got a copy of Riding Hero that I'm having issues with. I've cleaned the pins etc, but it always reboots following the SNK logo and chime. This includes if I add a credit during the chime/song. This is a behavior I've not seen before, and so wanted to check if anyone's encountered it before I go too nuts trying to diagnose it. Other games work fine in my test system. Issue is limited to this one cart.
