Similar...my colors are in a table so I can switch between PAL/NTSC with the right difficulty switch. So for a cheap effect I did...
ldy tvType ; 0 = NTSC, 1 = PAL
lda girderColor,x ; the girder for this walkway
eor GirderColors,y ; NTSC/PAL color table
sta girderColor,x
which is updated each frame.
Thanks for your's and Manuel's suggestions.
I do have a frame counter so it won't be too hard to implement.
Take care,
Dennis
