Crystal Dream II notes:
|
|
|
|
- Flickering issues, problems with vertical retrace timing.
|
|
|
|
If playing to GUS or Sound Blaster, the demo attempt to measure
|
|
the VGA refresh rate, then use IRQ 0 as sort of a vertical retrace
|
|
interrupt to synchronize demo page flipping and rendering to
|
|
the display.
|
|
|
|
For reasons unknown to me at this time, the demo will misdetect
|
|
VGA timing if core=dynamic. The dynamic core seems to throw off
|
|
the demo's VGA timing code.
|
|
|
|
If demo effects jump, run too fast/slow, and generally flicker
|
|
on screen, then the demo has misdetected the VGA refresh rate
|
|
and the timer is not synchronized with vertical retrace.
|
|
|
|
To avoid this problem, set core=normal or core=full.
