pub const MAX_CPU_OVERCLOCK: u8 = 4;Expand description
The largest CPU-multiplier overclock the core accepts (v3.1.0,
T-CPU-OVERCLOCK).
Nes::set_cpu_overclock clamps to 1..=MAX_CPU_OVERCLOCK, and a movie’s
options record outside that range is refused. The bound is the master
clock: the CPU divider must stay at least 3 for the read / write split of
a cycle (NTSC 12 / 4 = 3), and x4 is already four times the CPU time a
frame has.
