Well, I searched the net and found many versions of MSBoD, mostly the unregistered version. One version was registered, which allowed me to play up to level 21, and on one occasion, the boss did not appear (I went to round 22) and on one occasion it did (tried twice), but I vaguely recall that's not …

I remember the game crashing or hanging in (real) DOS before or during the appearance of a boss, or the boss not appearing at all, or getting stuck at a certain unreachable location. Though you might experience a DOSbox problem (it shouldn't crash of course), the cause is probably a bug in MSBoD. …

Re: X86 port to use host cpu directly

I just wonder, if Dosbox is slow, its mainly because it has to emulate the main processor (286/386 etc). So i wonder if it would be possible to make a special version for windows/linux that uses host cpu without emulation. It would probably need to emulate the memory part (protected mode etc) …

I have noticed that "IF ERRORLEVEL XX GOTO" is supported but "IF ERRORLEVEL=XX GOTO" is not. The correct syntax is "if errorlevel xx goto". The fact that the second syntax works also, has to do with the fact that the original DOS (at least the later versions) filters out any '=' sign as if it …

Budokan has screen artifacts when using DOSBox dynamic CPU core. Normal CPU Core is OK though, and run wonderfully. The dynamic CPU core is still in early stages of development, and should generally not be used. It is known to be rather buggy, so it's no surprise not everything runs as it should. …

anyone else finding anything similar? Yes, and it's been discussed here before. Check http://www.vogons.org/viewtopic.php?t=4210 .

Of course it would be perfectly possible technically to make this 'EXIT'-key in DOSBox. The amount of work involved would depend totally on the internal structure of DOSBox. If, e.g., the initial setting of many internal variables and structures was done by code like this: int some_variable = 0; …

The biggest problem you'd run into is the speed: 400 MHz is really not enough to emulate DOS programs at an acceptable speed. Maybe you'd just manage to emulate an original XT (4.77 MHz), but that's about it. Remember DOSBox is primarily a games emulator, and I doubt whether you'd be able to get any …

Not possible. Why? Some things are emulated quicker that others (DOSBOX does not keep the time relations as they existed on real PC!). You can have two programs which run with the same speed in normal DOS, but with different speeds in DOSBOX. In short: the equivalent Mhz value you want is program …
