Stop Swop 'N' Roll

Of all the secrets and mysteries in the Banjo-Kazooie series, none are more tantalizing or more talked about than Stop 'n' Swop. To use Stop 'n' Swop items, one would have needed to own both Banjo-Kazooie and Banjo-Tooie. One had to collect the eggs in Kazooie then switch the game off and insert Tooie. Originally, the player would have had ten seconds to swap game cartridges, but due to revisions in the Nintendo 64 hardware, the time was reduced to only one second, and therefore, became impossible.
