I saw the recent improvements in CDTV system. But in the game "Turrican" i have the output: "CPU maincpu: PULSE_LINE can only be used for NMI and RESET lines"
this has been properly fixed in svn 6203: the driver was checking for carts even if no cart could have been present.
now both Turrican and Turrican II (and probably other games as well) work fine.
