What do you have fullresolution= set to in dosbox.conf? If you're running RR configured to output 640x480 and your fullscreen resolution is 640x480, there's no room to add scanlines without losing pixels. Scanlines are image processing, not real CRT raster lines. Use a fullscreen resolution larger …

Wouldn't it be easier just to run the game with machine=cga ? That would be more or less equivalent to running the game with its -V parameter for a non-VGA display, which does not look as good: uglier colors, and no character-generator fonts, so the "graphics" are even more crude. But, they say a …

If you don't already know about Indenture, it's a freeware DOS re-make of the old Atari 2600 console game "Adventure". Remarkable for being a faithful reproduction of the original, right down to the quirks, it also adds significantly more challenge with higher difficulty game modes. Indenture's home …

CGA B&W video mode issue with machine=vga

In DOSBox 0.72, the 640x200x2 video mode 6, aka M_CGA2, gets an aspect ratio of 2.4 when using machine=vga. Being doubleheight, it displays 640x960 with aspect correction enabled... a tall screen indeed. It has the normal aspect ratio of 1.2 when using machine=cga. I would normally just use the CGA …

You'd expect multiplying and then dividing by 10 to cancel out with simple linear acceleration, so that sensitivity setting is apparently doing more than just that. A higher sample rate would account for it seeming smoother. BTW, an additional "feature" of MOUSEX is using negative speeds to invert …

MOUSE2KV doesn't always work. If there is no effect on the game in question, my guess is that it isn't installing a callback handler through the mouse driver, which MOUSE2KV relies on. DOSBox has a mouse sensitivity setting in the conf file, which I believe is directly used with setting the …

Hmm, I haven't encountered a single game where I've had to change those settings away from default values; but I guess there might be any number of reasons why your system is more sensitive to them than mine.

You might also try simplifying the environment in DOSBox by disabling the Gravis device completely (gus=false in the conf file). And, if possible, try manual configuration of the SB instead of auto-detection... when you say it doesn't matter which IRQ you choose, there's no need to experiment there, …

Another thread about a similar problem: Goblins 3 sound lag problem In short, a misconfigured SoundBlaster IRQ (e.g. game is configured for IRQ 5, but DOSBox is using IRQ 7) can cause sound lag, rather than the sound simply not working at all.

Looks like the debugger from some version of MS-DOS. The CS:IP is 0703:0000 and the SS:SP is 0703:0002 when you start off... not saying that's why the instruction isn't properly stepped in this case, but having the stack pointer on top of the code being executed can't be good...

It hangs because it can't find that 300MB file I mentioned. Do you have the CD or an image of it? If so, do a proper install from it, and then the music will work. If not, then you are going to have to get by without music.

The SETUP.EXE in X-Com Apocalypse hangs if it can't find MSCDEX; but mounting a CD -- any CD -- in DOSBox will make it happy. BTW, the music in the game is digital audio contained in a 300MB file called "MUSIC" in the root dir of the CD. It sounds like you're trying to use a rip of the game, and …

Also GhostView, and maybe others I haven't tried that kind of swirl the pixels on the screen. Maybe it's how often it has to redraw... I mean, if you're running along in DOOM, I imagine there are a lot of pixels changing, too.

What you observe is related to the time/date stamp problem. It appears so.

No it doesn't, it has a date/time command that changes the reported date/time but that's just useless. I am not sure what exactly its support amounts to, but I think it may implement INT 21/57 to some extent; because when you unzip files with PKUNZIP using ykhwong's build, the extracted files …
