What does how fullscreen appears with either ddraw or opengl make what I said about the blending of pixels not correct? Please stop changing the subject.

The point I made was not about what output looks more blurry than another. I said that blending of pixels will occur with aspect correction unless you use output=openglnb. Look at both of my shots, they both show the pixel blending.

Same as other shot, only with output=opengl. See any difference? There actually is a little bit, if you do a "difference" of the two images in Paint Shop, you'll see small differences in the blending. If you don't see the vertical blending of pixels going on in these shots, you need to look closer, …

The attached screen is with output=ddraw, scaler=normal2x, aspect=true. Look at the text in the menu.

If you're using aspect correction (aspect=true), you will get some blending of pixels unless you use output=openglnb ("nb"=no blending), and that is regardless of what scaler you use.

MORE is an external DOS program. It's not included in DOSBox. You can use one from MS-DOS, FreeDOS, or maybe some clone of it that does the same thing.

DOSBox screencaps are not corrected for aspect. You can either make your own for "doctoring" purposes, or the GPC title screen I posted has no aspect correction. Further than the horizontal blending process I've described, what kind of doctoring do you have in mind?

The GPC screen I posted is from a DOSBox screencap, which has no aspect correction. The shots tulbo posted appear to be using DOSBox's 1.5 pixel aspect ratio, so apparently are made by some other process and not by DOSBox. Viewing screens without aspect correction could also be called inaccurate …

Which screenshots are you referring to? There's a lot of them here. :) With aspect correction there is no such thing as "pixel perfect". openglnb will give you pixel blocks of varying height rather than blending, that's the only difference. Either introduces a form of distortion. For characterizing …

Real serial. My Intel motherboard has one serial and one parallel port: COM1 and LPT1. As robertmo pointed out in that other thread, I plugged the mouse in after WinXP had started up to avoid it being detected.

I've read that serial mice are 40hz, so 25ms per report, but maybe there's overhead or something. I haven't tried the serial mouse extensively, but in Windows 1.x with its bus/serial mouse driver, and in Tass Times, the delay is far more exaggerated than you describe.

Tass Times in Tonetown not running correctly Read robertmo's last comment. Known to those that have tried hooking up a serial mouse and using it. Perhaps not known to others. 😉

A serial mouse going through DOSBox's serial port emulation is known to have noticeable latency, but you only need to do that if the game/application only supports a serial mouse and not a ps/2 style mouse, or if you want to have two mice (one ps/2, one serial) for some reason.
Re: Got the sound working in "Arctic Moves".
Posted on 2011-02-11, 12:04
It uses segment 0x40 addresses 0x4F0 thru 0x4FF and 0x9EA (I think 0x9EA was not intended, should have been 0x4F0+0xA like the rest of the code, not 0x4F0+0x4FA) In DOS 5/6 the addresses are not part of a table, they are actually DOS code. The game swaps between several executables, and maybe the …
Re: Got the sound working in "Arctic Moves".

Sound works in the first mission when you configure a joystick in DOSBox, but it's not entirely effective because sound is still missing on the title and prologue screens. Sound works completely, regardless of gameport detection, when booting real DOS. The game uses hard-coded memory addresses that …

The mouse is disabled on the copy protection screen; use the cursor keys to move the highlight bar over the correct response and press enter. It does seem like it would make sense to be able to use the mouse on the copypro screen, but it's intentionally disabled by the game, for whatever reason. BTW …
Re: MIDI tracking

The closest thing I've seen are Texture and Prism , some of the first MIDI sequencers for PCs, programmed by Roger Powell of the progressive rock band Utopia. They use the word "pattern" to refer to a kind of "event view" (like a note view, but for events) which is similar to the pattern …
Re: Display problem of an old application in Hercules mode

Was the VGA card you were testing with an S3 model? The app searches the 0xc000 segment for the string "S3 Incorporated", and actually finds it, even though machine=hercules. So it seems writing 0x46 to index 1, and the illegal index reads/writes mentioned before, are an extra thing it does that it …
