Wii VC Round-to-Zero

Stream by Switchpalacecorner, after 71.5 hours of raising in Wii Virtual Console

After 146.5 hours (6 days 2.5 hrs)

Wii VC Round-To-Zero is a special phenomenon caused by emulation inaccuracy exclusive to Wii Virtual Console (Wii VC). This is a new glitch discovered on May 28, 2018, that contributes to the A Button Challenge.

In the Wii Virtual Console, it is possible to raise the moving platform at the beginning of BitFS, due to a rounding error that is unique to the Wii Virtual Console. It is believed this happens because the Wii doesn't round-to-nearest with floating point numbers, as the N64 does, but instead 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 had left their original positions.

Applications

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

The glitch was fully console verified RTA on 06/20/18 by ethanwhitesm64.

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.
