According to co-creator Gregg Mayles, the idea behind "Stop 'n' Swop" was to do certain challenges/objectives in Banjo-Tooie, then stop and swap the cartridges while the system was still on. This would have unlocked special items in Banjo-Kazooie. You can than swap the games again to get the items in Banjo-Tooie, and this would potentially extend to future Rare games, including Donkey Kong 64. This idea was scrapped when the window of time that players could "hot swap" games (the ability to switch games when the power was on) was shortened from 10 seconds to only 1 second. There are still cheat codes that will unlock the special items in Banjo-Kazooie. In the Xbox Live Arcade versions of both games, the methods to obtain the Stop 'n' Swop items were changed to instead be tied to recognizing save data for Banjo-Tooie or Banjo-Kazooie: Nuts & Bolts. In the 2026 Evercade ports of the games, the Stop 'n' Swop system is reimplemented after beating the game, and allows players to unlock additional cheats, and a music player featuring early unused versions of certain level themes.
