Add Ignore Double Speed option for CGB performance
...
Games running in double-speed mode (8MHz) cause the emulator to execute
twice as many instructions per frame. This option ignores the double-speed
flag, treating all execution as normal speed for better performance on
slower Macs while maintaining correct frame timing.
- Add menu toggle in Options menu
- Save/load preference to resource file
- Check flag in dmg_sync_hw() when calculating PPU cycles
