What is stop n swop in Banjokazooie?

Answer:
Stop 'N' Swop was a feature that was supposed be (but wasn't) in Rare's Banjo-Kazooie N64 games. (The XBLA versions have included it though.) It was mean't to transfer some specific secrets from Banjo-Kazooie to Banjo-Tooie. To do this you would've had to pause 'Kazooie and (very) quickly swop 'Kazooie for 'Tooie, thus transfering your secrets.
