Help¶

This option enables the RNG bias correction, which guarantees a uniform distribution of 0 and 1. When this option is enabled, the time to generate a byte cannot be guaranteed.

Direct dependencies¶

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
