The first couple of Christmases were the worst, by shipping something they got you hooked.
My original c64 has always had major graphics corruption, there appears to be a timing issue on colour ram when one of the scroll positions is used. I ended up missing it when using an emulator or c128. Most games weren't affected as they didn't scroll color ram, but there were a few games that became so unplayable I had to fix them by changing the scrolling from 1 pixel per frame to 2 pixels every 2 frames.
