If the game relies on vertical blank interrupts (which most do) you might be able to run the CPU at 1/10th the normal speed and still have the game look and play fine. It depends on the complexity of the game. If all of the functions for a frame are completed prior to the next vertical blank, it could just sit in a busy loop waiting on the vertical blank flag to appear so it can process the next frame.
