for x=1 to 5
for y=1 to 2
array1(x,y)=array2(x,3-y)
next
next

this should work, i think.

Simple man, instead of writing the image from ymin to ymax, write it from ymax to ymin. Since you only need 180 degree rotation. Hope you get the idea.

Code:

defint a-z
sub PutFlipV ( dstseg as integer, xd as integer,
               yd as integer, image() as integer )
    
    static dstofs as long
    static xmin as integer, ymin as integer
    static xmax as integer, ymax as integer
    
    
    def seg = dstseg

    ''
    '' Calculate offset
    ''
    dstofs = yd * 320& + xd    
    
    ''
    '' Calculate sprite dimensions ( or not :P )
    ''
    xmin = 0
    ymin = 0
    xmax = 64-1
    ymax = 64-1

    ''
    '' Blit sprite
    ''    
    for  y  = ymax to ymin step -1
        for  x = xmin to xmax
            poke dstofs+x, image( y, x )
        next x
        
        dstofs = dstofs + 320
    next y
    
    
    def seg
end sub
