Thanks! And why are some instructions marked as [illegal]? Does it mean they were ignored by dosbox core? Or maybe debugger opcodes are decoded outside core, and can be interpreted incorrectly, even though core execution was right?

I've compiled a heavy debug version of DOSBox, and I wish to use it for dumping a function from dos4gw-based game. I already found a way to locate the function ('BPINT 21h 3Dh' - opening a file), then I'm dumping it with 'LOG'. But I'm not sure which core should be used for suchy dumping. I've …

Syndicate Wars works great in DOSBox. Try downloading patches and DOSbox config file from: http://syndicate.lubie.org/ It looks like inside the "strategic mission" you can set greater cycle rate than in a menu, without sound shuttering. On my P4 2.4 I can set up to 65 000 in mission, and only to 45 …

Windows XP seems to react the same way - it's trying to send any data directed into file "LPT1" to the real …

I was right: the reason is disabled LPT port. When I enabled this port in BIOS, Puff started working properly - so we have temporary solution. ...but it is easy to add an "if" in a right place to detect if we're sending to LPT. This bug can be corrected without writing LPT emulation... i think. ps. …

There is a problem described in many posts: some applications, on some machines, displays "Runtime error 008" and exits. I think i've found the reason: a printer port. I don't know how DOSBox reacts on a command to send something on LPT1, but it looks like it is trying to send this data to a real …
