I don't have a Korean board, but I was always wondering why it can only play the samsho games. I know that Beast Busters and driving games have custom pinouts, but the Korean board supports fighting games.

What's keeping it from running Buriki and Wild Ambition? Does it run a CRC check and if it doesn't correspond to the one of samsho games, it throws up and error?

If so, that's truly bizarre. Are the internals of the Korean board exactly the same as the fighting board?
