Pre flashed DIP Saturn bios chip, suitable for VA0 and VA0.5 consoles.
All bioses work on all consoles. Until splitting this listing we always supplied the Japanese bios for all users. But now you have a choice. Japanese is what came with all standard Japanese Saturn's and has a different intro noise. Worldwide is what's used everywhere else.
Both the Japanese and the World Wide bios has all language options, including English.
The others are custom for the special versions of the Saturn's, but will work on normal ones if you fancy something different.
