In debugger:
v -1 : enable only, no visual mode. v -2 : enable + visual mode v -3 : enable + visual mode + doubled horizontal pixels Note that currently mode can't be changed after it has been enabled. After it has been enabled (visual or not), v <vpos> <hpos> shows detailed scanline DMA/CPU usage. |

btw, remember to enable copper debugger first (od). Then check copper list (o-command), use it to find line you need DMA details, then use v-command to see exact details. Quote:
green = blitter dark green = blitter line bright green = blitter fill blue = bitplane cpu = gray audio = red sprite = white disk = purple Vertical line on the left side: CPU interrupt level. |
