On the issues with VSync: Are the problems you're having with VSync under Linux specific to the SDL 2.0 builds? What about SDL 1.2 builds, either of vanilla DOSBox, my patch or an older revision of dosbox-staging? Linux vsync issue was the first regression we found when merging in SDL 2.0 - we …

I have very little experience with Linux and never used dosbox on it, but it seems that on Linux it needs some bug fixing. I spend almost all of my time on Linux so do most of my time testing on Linux, so I know about the issues affecting Linux. But judging by questions and complaints posted here …

Apparently I was one of the few people on earth which typed "INTRO" at the command prompt and read it. But yeah, Dosbox is what it is. Can it be improved? Sure but at the moment it's still the best and most versatile Dos emulator. INTRO is not going to describe e.g. why MIDI port detection does not …

How i can create that mapper file by hand? Do you have one around to attach here? Build dosbox-staging on Linux, run it, press Ctrl-F1, click "Save" - it will generate a new mapper file for you (it's a text file - you will have no problems with editing it manually), and it will be automatically …

@Gernot66 The problem is rooted in using SDL 1.2, which is unmaintained since 2013. Some Linux distributions are starting to drop SDL 1.2 from the repositories because almost whole open source world moved on to SDL2, DOSBox is one of very few stragglers.

@serdeliuk I think for quick and dirty proof of concept, you can try this: in src/gui/sdl_mapper.cpp find all uses of SDL_SCANCODE_LCTRL and replace with a scancode you probably added for a RED button. After that, you'll want to re-generate or manually edit mapper file (path to the file is printed …

On Windows 10 I had the same behaviour in VLC: audio plays, no video. I did several more tests on Linux and the situation is more complicated: videos recorded via DOSBox do not work correctly in general (different bugs in different players; bugs exist since 0.74-3 and are still happening in r4314). …

I am not even talking about GUI. How about starting with simple things, like making output=opengl the default instead of surface. In dosbox-staging I added a tiny feature to display drive label above output of dir command (as it was in DOS), so it's easier for users to identify which floppy image is …

There's no such functionality built-in, but you can switch to different text modes manually - there was a post about it some time ago (I can't find it now), and in there ripsaw8080 posted a set of utils to change to various modes. Just run e.g. 80x50.com and you're done (you can add it to autoexec …

Hi, i need to make some tests but maybe this part in vga_draw.cpp would be a better place to do endian conversion, it would give clean BE output and doesn't require PMAKE changes, it could be also Altivec accelerated in easy way. I'll make some tests and let you know (and need to check how memcpy …

@Jmarsh Thanks for fixes in the main DOSBox repo! I checked now PMAKE changes and yes, 15,16 and 32bit modes all render correctly now. Through capturing of screenshots via ctrl+f5 in 15/16 and 32bpp still save it as before with those ugly colors: http://kas1e.mikendezign.com/aos4/dosbox/badcolors/ …

Edit a bit previous post. Strange that on my setup (some ppc box) with vsync=false i have 50% speed drop. But i not sure if it because of SDL2 at all, probabaly just because of dosbox use opengl as blitter and update textures each frame. What does it mean "some ppc box"? :) Anyways, here's my test …

Is that patch tested with the OpenGL output too? Yes. Aren't there issues with speed drop when used OpenGL output in DOSBox with that path applied? When using with vsync=false (default), there are no performance drops (tested on several Linuxes and Windows 10). When used with vsync=true on Linux, …

1st unnecessary bloat, most games run without fine tuning. I don't think it's true… even the most popular DOS games need tweaking. For games from 80s it's rather unavoidable and that's fine, but for popular games from early 90s? I can't remember a single game I tried in last ~6 months that didn't …

-conf definitely does work, so you should double-check your path. All DOSBox versions confirm which file was used by printing a line prefixed with CONFIG to the log. e.g. for me, it looks like this: CONFIG: Loading primary settings from config file /home/dreamer_/.dosbox/dosbox-staging-git. …
