Re: Do I need multiple DosBox apps?

You can create multiple config files and start Dosbox with a specified config file using the command line.
Re: RS232

So using the serial port with Windows 10 + Virtualbox + XP + DosBox + Windows 3.11 was successful, right? If so, then the USB/RS-232 adapter is probably working correctly. If Windows 3.11 works on Virtualbox or some other virtualization software (I don't know if it does), it might be less complex …
Re: Distribute DOSBox Install Package
Posted on 2020-08-14, 13:33
GOG basically does that when they sell old DOS games. But their installation tools are probably not publicly available. While DOSbox is not desined to run non-games, if your software works well and your goals are not super professional, DOSbox can be a good choice as well.
Re: Trouble with my serial port communication in DOSBOX
Posted on 2020-08-01, 17:14
I understood that you used DOSBox with that CNC control software on Windows 7, and the same PCIe -> RS-232 card. And everything was working well. Is that correct? Which DOSBox version are you using? I think someone said that serial issues were fixed in the newest (or SVN) release. Are there …
Re: Running Dosbox on a CRT
Posted on 2020-07-27, 10:10
Yeah, that's what I thought... How about monochrome displays? Were they ever manufactured with uniform (non-pixelated) phosphor screen? edit: Probably yes, for example in old analog oscilloscopes. But how about computer monitors?

From that Sophos blog link: When Microsoft first shipped this feature as an upgrade, you had to enable it. In fresh installations of Windows, it was turned on by default. So if it was enabled by an update, maybe try disabling it? Have you tried that?
Re: Side Scrolling problem

Can you post a picture or video of the problem? Does the problem only occur in full screen mode, or in window mode as well? Frame rate mismatch, or non-integer scaling of resolution? Just my 2 cents. More details about the problem would be useful.
Re: Running Dosbox on a CRT
Posted on 2020-07-17, 07:33
Windows' claim as to the native resolution of the monitor is likely based on its interpretation of your HDMI to VGA converter . CRTs do not have a native resolution . [OffTopic] Isn't there some upper limit which is caused by the number of red/green/blue zones on the CRT mask? At least in non- …
Re: Is There A Way to Only Have One Copy of DOSBOX Installed?
Posted on 2020-07-17, 07:26
I've taken some GOG games out of their installation directory and mounted and played them manually using DOSbox. It requires lots of manual work. Using symbolic links sounds like a good solution.

Re: Is there a way to set a breakpoint that activates when something is written to a specific port ?
Posted on 2020-05-19, 14:41
I think this is not possible... Only basic breakpoints (break at address xxx), interrupt breakpoints (break when interrupt xxx is about to be executed [with al=yyy and ah=zzz]) and memory change breakpoints (break when memory at address xxx is changed) can be set. Just my 2cents. Have you tried to …

I see incoming trash traffic all the time in the log of my router which is online 24/7. And so far nothing bad has happened. I think the traffic amounts have actually decreased since the worst IoT malware epidemics. Hackers don't cause your hard disks to break. The correct method of protection …
Re: Capturing movie with MIDI

Hello. When I'm executing a program with MIDI sound (playing via MPU-401 ports 330h/331h) I hear the sound. But when I'm trying to capture the movie (Ctrl+Alt+F5) the sound is not recorded. I.e. it is played but not recorded. Why? And how can I resolve this problem? p.s. When I use audio editor ( …
Re: DOSBox and resolutions and scalers and SVN - How to scale with HQ5x or xBRZ 5x or 6x? windowresolution valid values?
Posted on 2020-03-02, 16:26
Perhaps you already know this, but if the original resolution is above a certain limit, you have to add "forced" after the scaler option, otherwise it won't activate. And there are also hard-coded resolution limits that disable scalers and they can only be overridden by patching Dosbox. I don't know …
Re: Germicidial UV-C lamp for Retrobright

There are a couple of youtubers that have success with UV-A / UV-B lights or even bare blue LEDs that are normally used with the yellow phosphorus, in combination with hydrogen peroxide. I’m not sure if UV-C has the same effect as it doesn’t occur naturally (especially indoors). I can confirm that …

As far as I remember, mercury lamps radiate UVC at two wavelengths and only the shorter of them produces ozone. If you want ozone, make sure that your lamp does not filter the shorter wavelength. Some lamps do.

They are even easier to solder than through hole ones when using a proper fine tip soldering iron. I agree, but you need good equipment. SMD soldering with poor equipment is real pain. Some tips that may be useful, from my personal experience: -Use a good quality, adjustable soldering iron with …
Re: Ways to dump memory to a file->
Posted on 2020-02-05, 13:35
Hm... in many cases it might be a better idea to dump memory into a binary file instead of text...? Then you can examine it using a hex editor (if you know what you are looking for) or load it in a disassembler if you want to analyze the code parts. But if you want to examine the game code, try …
