In the Wii Virtual Console, it is possible to rise the moving platform at the beginning of BitFS, due to a rounding error that is unique to the Wii Virtual Console. This is thought to happen because the Wii doesn't round-to-nearest, as the N64 does, but instead it rounds-to-zero. Since the moving platform is below 0, it tends towards it. It is possible to DR in about 8 days, and it is possible to VSC with a lava boost in 3 days.

The glitch was discovered by andru when he went to sleep leaving the Wii powered on for several hours in Bowser in the Fire Sea (BitFS), and found that the oscillating platforms left their original positions.

Applications

Currently, only the blue moving platforms in BitFS in Wii Virtual Console are known to have this property. All other consoles such as the original N64, WiiU Virtual Console, Shindu, do not have this rounding error.

The glitch, so far, is waiting for an RTA verification and not fully confirmed yet.

The first attempt, by ethanwhitesm64, failed because he DR'd to early and missed the platform.

The second attempt, by barruuuu, failed because after a successful DR, he overshot the elevator and when he ran back, he fell through the hole.

The third attempt, by Switchpalacecorner, failed because after a successful DR, the top moving platforms loaded and moved down below the lava. While it is possible to get the next platform using the side ledges, Switch missed it and fell down back to the first floor.
