2. Turning off the game when you are about to make a serious mistake DOES NOT WORK. The game secretly has an auto-save feature added in, but you don't notice this until you turn it back on and realize that the time is different from the last time you saved. So, thanks to this, there's zero room for error in a speed run.
I think you can bypass that one if you pull the cartridge out, but I don't know for sure.
The fastest time I beat Banjo kazooie was 3 hours and 47 minutes.
