I'm a bit puzzled what it tries to do here. Wonder if our seek on NUL matches that of real DOS. 60723059: FILES:Special file open command C0 file NUL 60723060: CPU:Illegal/Unhandled opcode 63 60723062: PIC:0 mask F9 60723064: PIC:0 mask F8 60723064: PIC:1 mask EC 60723078: CPU:Illegal/Unhandled …

Re: Boot DOS and read CD?

in DOSBox General
well I don't have this game. So I can't confirm your findings. But basicly this would mean that if you are right then this game wouldn't install on a real dos pc as well. As that returns removable for a cdrom.

Re: Boot DOS and read CD?
