The issue occurs when I create a new View with TAG_VIEW_GLOBAL_CLUT equal 1. If you declare 2 different vPorts and the second vPort has more BPP than the first, the...
With something like this: ``` #include // ... fix16_t XCoord = 0; fix16_t half = fix16_div(fix16_from_int(1), fix16_from_int(2)); // calculate once if possible // ... if(right) XCoord += half; // draw...
On Amiga hardware, sprites are each a continuous DMA with an individual line of pixels separating each "window" of graphics data. During that separator, the chipset fetches the next location...
When using dual-playfield mode there are seldom enough colors to look good so making the copper manager merge multiple priorities of color changes (and other stuff) that don't line up...
