DMA debugger and 14Mhz 68K
Hello Toni,
I was playing with the visual DMA debugger (v -4, Winuae 2.8.0) and tried to change the 'cycle-exact CPU emulation speed' to 4x.
With my surprise the black & gray pattern are still visible in the DMA debugger.
I supposed that a 14Mhz 68K uses all the available access slots.
I expected, where not in competition with DMA, only gray dots visible.
Instead, regular columns of gray dots are visible.
See the attachment.
It seems the 68K doesn't have access to 2 consecutive slots or most of the instructions don't use continuously the RAM.
Can you explain the behavior?
Thanks for your hard work!
