Add experimental "overclock" option
 2017-10-04 02:31:43 +02:00
Brian Koropoff
2135365d5c Add experimental overclock option. 
This reduces all cycle costs by half for the primary CPU.  There
is a delay upon loading before overclocking is applied as a
workaround for some games that detect PAL/NTSC systems by counting
cycles in a frame at startup.
