I've found the culprit. It was fulldouble=true. With fulldouble=false, things work very well. Howver, in the course of experimenting, I found a couple of strangenesses: fulldouble doesn't seem to be compatible with output=surface. The screen was very messed up. Only output=ddraw will scale up …

robertmo, thanks but I'm already using the dynamic core, and adding more cycles makes the game too fast, as I wrote. MiniMax, I tried your suggestion, also with lower numbers. The result was the same as for plain cycles=max: stuttering in the intro and a game that runs too fast to be playable. I …

I can't seem to find a cpu speed setting where the lip synch in the Ultima VII intro is correct without the game proper being much too fast to use. I use 0.73 on Windows XP home SP3. Machine is a Aspire One netbook, Intel Atom processor @ 1.6 GHz, 1 GB of RAM. No frontend is used, I prefer to edit …

Guys, I'm not planning on stopping your enthusiasm, but there was a reason those games didn't use mode 6 in the first place. Mode 6 + burst bit is pure artifact colors; in mode 4/5, the artifact colors will combine with the color-circuitry colors in a specific way. Basically you have those luminance …

I think it's a better idea to allow the user to toggle between RGB and composite with a key combination, if that's possible. Sure, but being able to set a default from dosbox.conf would be good for front-end users; then you could set up every game the way it needs to be. Maybe machine= wouldn't be …

The "code" he did (algorithm) is in dosbox. For a few games it'd be additionally required to force-select that mode. Thanks wd. There is currently no option to do this "force-selection" from dosbox.conf. right? Have you considered maybe splitting machine=cga in two, e.g. machine=cgargb and machine= …

They look perfectly straight and centered to me, with no glare. You're right, in fact. My own CRT monitor was playing games with my eyes it seems. Still I don't know how they did those images, or how to enable that mode in DOSBox as I said. EDIT: I just saw that those screenshots were done by …

I'm confused - DOSBox is able to emulate CGA composite mode graphics... I'm pretty sure the composite color screenshots on MobyGames for Ultima 2 are from DOSBox. I'm aware that the 640x200 purely artifact based composite color mode is supported with machine=cga. But that's not the mode Ultima II …

It should be stated though that Ultima II and III are meant for a graphics mode that DOSBox does not support (CGA 320x200 mixed-color-and-artifacting composite graphics). So they will look like they would on most newer PCs in native mode, but not the way they were supposed to look when they came out …

Your program is obviously, for some strange reason, interpreting keyboard scancodes as ASCII character codes. I have no idea why any sane DOS program would do this, as the two sets were always quite different. Edit: I seem to remember, very deep in the back of my head, that there was some BIOS (or …

Given that the CGA/EGA/VGA vsync frequencies and the basic frequency of a PC's interrupt timer chip are both derived (by integer multiplications and divisions) from the NTSC color carrier frequency of n = 3.57954545454...

"DOS games" as such did not run at 70 Hz, it depended on the graphics card. Not counting non-standard modes, it's as follows: MDA and Hercules used 70 Hz. CGA and EGA used 60 Hz. VGA used 70Hz for 350 and 400 line modes (including double-scanned 200 Line modes), and 60 Hz for 480 line modes. For …

If your Monitor is connected via VGA analog, the horizontal resolution the monitor shows means very little, because there is no easy way for the monitor to detect it. My monitor for example always reports 640x400 for any of the 70Hz 400-scanline standard VGA modes (320x200, 640x200, 640x400, 360x400 …
