Some improvements to Sandii' games:

Browse Source 
- Confirmed the CPU clock after some PCB measurements.
 - Changed the SND clock to 1MHz to match the PCB measurement.
 - Corrected the internal OKI6295 frequency turning the pin 7 state to HIGH.
 - Inputs: Eliminated all pulse limitations.
   Affected buttons have a rattled sound in the real thing too.
 - Updated technical notes.

Please also co-credit f205v for the measurements.

*** Driver Updates ***
[2008/05/22]
- Confirmed the CPU clock after some PCB measurements.
- Changed the SND clock to 1MHz to match the PCB measurement.
- Corrected the internal OKI6295 frequency turning the pin 7 state to HIGH.
- Inputs: Eliminated all pulse limitations.
Affected buttons have a rattled sound in the real thing too.
- Updated technical notes.
[2008/04/28]

*** TO DO ***
- Figure out the unknown reads to offset $3004, bit 7.
- Get CPU and sound clocks properly measured.
- Get the OKI6295 pin 7 measured to know the real status.
- Hook lamps.
- Turn the color system to resnet calculation.
