This is a page dedicated to disambiguate the hardware differences between playing Metroid Prime on a Nintendo Gamecube and a Nintendo Wii.
All videos here are single-pass and perform actions similar enough to isolate only the load times. The Gamecube videos are darker and of poorer quality because of the composite connection, but also most of them will be on the left.
The numbers reflect the number of frames it takes for the door to open completely. The start frame is synced to a door shot, entering a load trigger, or a synced action which is simple enough to isolate the load time. The end frame occurs when the shell of a door opens entirely, with no hexagonal piece still overlapping onto any part of the door.
