: HHHHHHEEEEEEEELLLLLPPPPPPPPP !!!!!!!!! Well, I'll do my very best... Let me guess: you said 'yes' to tv-output when installing the Rainbow Runner card? You can read a lot of wierd things about what this installation routine can do to your Mystique at the bulletin-board of the Rainbow Runner User Group http://www.wantree.com.au/~dunn/rr/my_html/bulletin_board.html This is how I nearly fixed the problem: run the setup program from the Rainbow Runner CD again and disable the tv-output. This should correct your RAMDAC frequency (whatever that is...). You may also update your Mystique bios to version 1.6 afterwards. I can play Balls of Steel now, but the scrolling is awfully jerky. I hope I can fix that later. Let me know if (and how far) you succeeded!
