The conf file note for autolock states that it happens if you click on the screen . But my experience has been that it won't autolock by clicking until you run a game or app that actually uses the mouse. For example, just starting up DOSBox to the prompt, it won't lock by clicking (it will with Ctrl …

How are you recording the output from DOSBox? I'm only curious to know if something might be altering it in the process of recording. One thing that stands out about the waveform from DOSBox is that the DC Bias in the right channel is shifted so much that some samples appear to get clipped in …

I don't know much about audio processing; but that article suggests using a low-pass filter.

The screenshot you got from Google, lemmprob3.jpg, appears to be from the Amiga version of Lemmings if you compare to shots on Mobygames -- a poor comparison to the DOS version. I didn't see a mention of you trying different video output methods in DOSBox; not that I think changing it is likely to …

With the core set to auto, that should be using normal core because the Adlib programs are not protected mode applications. Anyway, it's good you figured out a solution.

The installer for System Shock cares about the labels on the diskettes. Try mounting the A drive such as: mount a A:\ -t floppy I'm not sure if identifying the drive as a floppy allows the label to be read from it, or if there's something else at work, but doing so will placate the installer.

I don't have the game, but I downloaded the 2-disk patch to v1.4 and using the DOSBox debugger found 2 issues that keep it from working. INT 21/52 "list of lists" byte offset 20h is used to get the number of block devices installed. DOSBox reports 0, the install program expects at least 2. I changed …

SUBST is an external command in real DOS, but in DOSBox the command works similar to MOUNT. If you are mounting the A: drive ahead of running the batch file, the "SUBST A: ." it is doing to make the current directory the virtual A: drive will fail because the drive is already mounted. So, try not …

I'll say it again, since you ask again: the call command only applies when running one batch file from another; it is not used with executables. Without CALL, you are transfering control to the other batch file, never to return. I can not explain how you are getting CALL behavior without using the …

Recursing the subdirs meaning looking into subdirectories for files as well. The /S switch on DIR, for example. If you are piping the DIR /B into a file and parsing that into selection lists and so forth, you would probably find using DIR$ easier than what you were doing; even if it is a new trick. …

If you can upgrade to Extended QuickBASIC, you might be able to use the DIR$ function to do what you were shelling to DOS DIR for. It does not recurse subdirs, though.

I am reminded of the old saying "In for a penny, in for a pound." Your view is a bit narrow when you say that it takes little time and effort to implement. While you may think it's acceptable to have a 4x version of the simple scaler without a 4x version of the other 2x/3x scalers, not everyone will …

I'm not sure what you're referring to, but I think you may want to look at the game setup for making the mouse aiming key a toggle (on/off), or a momentary key (while the key is held down). From the setup main menu: Controller Setup > Setup Mouse > Mouse Aiming Mode

Your output method will also decide how scanlines look to a certain extent... how they are blended into the image. With output=ddraw, my display is dimmed when forcing scanlines from a game output of 640x480 into a 640x480 fullscreen resolution. I didn't say the scanlines would be finer at larger …

Daggerfall uses a 320x200 display mode, unless there's some VESA/SVGA enhanced version I'm unaware of... The larger your fullscreen resolution is compared to what the game is outputing, the better the scanlines will look; because there are more vertical pixels to work with when processing in the …
