skipDraw and graphics

[Ecernosoft]

Actually, this version is 35 cycles, and can handle a any-height sprite too so use this instead:

Origonaldraw        

         ldy P0height; 3
        lda (P0ptr),y; 8
        sta GRP0; 11
        lda (P0col),y; 16
        sta COLUP0; 19
    cpx P0Ytemp; 21
        bne Not1; 23
        dey; 25
        sty P0height; 28
        beq Not1; 30
        dec P0Ytemp; 35
Not1

 

The cons are:

1. Need Ytemp to be set every frame, along with spriteheight value

2. Need 0 at top

3. You can't split this apart like other kernal.

The pros:

1. Faster than Superdraw (Including flexible height AND multicolor) by 2 cycles.

2. This supports Flexible height and multicolor

3. Removing Color shortens this down to 27 cycles
