My DC would sometimes not read the cds and instead go to the home-screen. After several times of opening and closing the lid the game would start. I fixed this by opening my Dc and putting a piece of tape on the switch that checks if the lid is open. This works fine with all games I have, so there is no problems. Though, when I tried an emulator that required switching to a rom-cd after loading the emu, it continues to spin (well, ofcourse...). I put the other cd in but it would not find the roms. This is not a big deal since I really don´t need that emu. Then a thought struck my mind : Might the same thing happen with games with two or more cds? Or how does the switching works then? Are there any Dc games with more than one cd?
