f3e0641b1b Allow more fine-grained overclocking 
Some games can benefit from a little overclocking but start behaving
strangely at 2x.  Make the internal overclock ratio a fixed point
number and add 3 fractional settings.

[Core/CPU] add optional 68K and Z80 overclocking
 2017-10-04 11:19:10 +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.

cc056b92db [Core/Sound] fixed PSG power-on latched register (verified on VA4 MD1 hardware) 
Initial test that indicated power-on latched register was noise attenuation register was flawed because it wasn't done after a "cold" power-on. It appears the latched value is not totally reseted when doing a quick power off/on cycle (which was done with initial test) and would keep last value being set.

cbd2bc3d47 Add new core option: Core-provided aspect ratio. 
Available options for core-provided aspect ratio are "auto", "NTSC PAR" and "PAL PAR".
- NTSC PAR forces pixel aspect ratio of NTSC tvs always, regardless of game or core region
- PAL PAR forces pixel aspect ratio of PAL tvs always, regardless of game or core region
- auto works as following
-- NTSC PAR is used when core region is set to auto and game region is NTSC, or core region is set to ntsc-u or ntsc-j.
-- PAL PAR is used when core region is set to auto and game region is PAL, or core region is set to pal.
-- 6:5 PAR is used for Game Gear games, if core options Borders and Game Gear extended screen are both disabled
