as per Saturn goes, like the Turbo, it used to be only US releases were affected. Japanese resellers caught up and know they can sell at collectard prices to the crazy americans.
Only cheapies are those where the language barrier makes them unplayable.
Best is to give up and play from backup discs, Saturn CD drives seem to be as reliable as PC Engine ones and suitable replacements are widely available as well. In some cases I rather play on an emulator because of fear of losing progress.
