over the last couple of weeks, i've picked up a few boxed japanese megadrive games at my local swap (herzog zwei, rastan saga II, moonwalker, ghostbusters, golden axe and super monaco gp). all of them work in my nomad except for super monaco. i've cleaned it a few times and adjusted how far i put the cart in the slot, but have only gotten a black screen. is there any known incompatibility between super monaco and nomads, or do i just have a bum cart on my hands? thanks in advance.
