This is the default setting.

I can?t implement functions that reprogram the graphics card in this way, and I could line up a long list of argument why, but the short answer will be: if you want to implement this you have to do it yourself.

Most of the console function calls @rcsprc (src/clib/console/rect/_rcsprc.asm) to create a screen pointer from x, y (bl, bh), but some functions are hard coded and add 2*80 to get the offset of the next line.
