,/* LMMV */
==== LMMV ====
* LMMV seems to operate as if it is in bitmap mode all the time.
* SC comes from FC when applied to LOP.
* When DIX=0, then FC low then FC high are used to write pixels. The order is value restarts each row and FC high/low are not reversed when DIX=1directly related to VRAM like WM is.
e.g. When 8bpp, fc=&1234, DIX=0 and nx=4 then after LMMV has executed we will see the bytes in vram: &34,&12,&34,&12.
* When 8bpp mode, fc=&1234, DIX=1 and nx=4 , then after LMMB has executed we will see the bytes in vram: &12result is a bit strange,&34,&12,&34it depends on the DX value.* FC bits do not correspond directly In P1 mode, LMMV seems to physical VRAM but do match the pixels in each byte.e.g. operate as if x=0, 4bpp,fc=&1234 and nx=4 we will see in vram &34bitmap mode,&12. If x = 1, 4bpp, fc=&1234 however the value written to VRAM1 varies and nx=4 we will see in vram &x4,&32,&1x where 'x' it is the data that is already in vramnot known why yet.
