@Ciello Oh yeah, since I actually did my research about why Uncle said Saturn was 64bit:
Saturn was falsely marketed as 64-bit. They were marketed in such a way that it appeared to be an evolution of the "16-bit" era of video gaming dominated by the Mega Drive and Super NES (which in turn succeeded the "8-bit" Master System and NES, respectively).
This description, however, was initially fabricated - Sega of Japan originally claimed the Saturn was a "64-bit" console[14] and some within Sega even chose to call it an "128-bit" machine,[15] a number arrived at by cumulating processors rather than simply picking the main CPU. Alternatively, some areas of Sega simply went down the "multi-processor" route, refusing to get drawn into the perceived differences between 32-bit and 64-bit.[16] This was incidentally the last video game generation where these so-called "bit wars" were considered to matter.
