RMAC and "branch" - OP opcode

Recommended Posts

the latest RMAC generates branch with wrong YPOS (shifted left by one bit), and also doesn't truncate YPOS to the max value $7FF

is it ok?

 VI increments twice per scanline.

ok, VI counts halflines.

theoretically, in interlace mode, in the even field, a scanline starts with even halfline, and in case odd field - odd halfline. Now we have branch for only even halflines

 

and anyway would be cool to have values truncated for OP opcodes
