Maybe they are corrupted then I don't know your settings look right and it is loading the one game if you are getting that screen it is launching the emu its telling you it doesn't recognize the disc. Try changing your disc plugin to gdrimage Is GTA2 a cdi file or a different type and that is why it works? I don't use the same settings as Brad I use the other disc plug in in Demul and in LB under manage emulator I use the No space checkbox in Demul for DC and then for the Arcade stuff I name the emulator Demul [Arcade] in LB and point it to the same exe as DC but then check No Space use file name only and Attempt to hide console window. Its possible the chd plugin doesn't support cdi extension. I'm not sure but try those changes
