3 years ago It is on rpi4, with the dosbox binary compiled against SDL2. Same config does not crash with other DosBox variants (e.g, Dosbox-staging).

3 years ago @Drag0nFly There is a delicate page for this demo (a.k.a. "Unreal" by Future Crew) in the DOSBox-X Wiki, please try to use the configuration mentioned there:

3 years ago Tried the suggested .conf file. The demo runs, however extremely badly (the worst performance so far); audio stutters all over the place, with low fps even running in a tiny screen size. Definitely not meant for a Raspberry pi.
The image is also relegated to the bottom left-hand corner of the screen (covering about 1/8th of a 1080p screen). Switching to, e.g, dosbox-staging (and dosbox-sdl2) with the exact same .conf file, the screen is full-size so there must be some default setting somewhere. Performance-wise -staging and -x behave quite similar. However, -*sdl2 runs better but has some graphical glitches.
Dosbox-X still crashes with the .conf file I provided earlier (which runs on all other DosBox flavors I've tested, the smoothest so far – although being far from smooth it is playable on rpi4)
The only info in the log when this occurs (right after selecting the soundcard & launching the demo is):

DOSBox-X has switched to max cycles, because of the setting: cycles=auto.
If the game runs too fast, try a fixed cycles amount in DOSBox-X's options.

[gus]
gus=trueAs for the config file shown in the Wiki page, you can get better performance by changing:
core=normal
to:
core=dynamic
With this change the audio no longer stutters here. But please note that config files as provided focus more on accuracy rather than performance. If you want better performance try to change the config settings or try a different DOSBox build.

2 years ago On my machine (DOSBox-X 0.83.18) it crashes at the start of vector balls... It runs on DosBox 0.74 though. "Because of a bug, this part will crash if the demo is installed in a directory with the complete path length exceeding 30 characters." That's not the case, I have got it in c:\second. The only issue with the DosBox 0.74 is the Plasma Effect does not look so good. dosbox-x.conf.zip

2 years ago I run it from C:\ which seems to work. Can you try that?
The plasma effect requires some per-scanline manipulation of the Offset register to make it warp. SVN by default will only render the screen in quarters instead of per scanline, which doesn't work well with that, however SVN has per-scanline rendering (like DOSBox-X always does) if you specify machine=vgaonly.
Of course playing music AND doing this plasma effect is not 100% perfect, interrupts seem to cause an occasional (maybe once every 1-2 seconds) one-frame glitch.

Yes, I do that. That's not the case.
if you specify machine=vgaonly.
Can I do that in DosBox 0.74? The demo works fine here, except the plasma effect looks worse than in DosBox-x.

2 years ago I'm not sure about that, DOSBox 0.74 was a loooong time ago. I think that code might have been added by then, not sure.
DOSBox 0.74 and SVN render the VGA display one quarter of the screen at a time, not per scanline. However machine=vgaonly will render per scanline if I recall correctly.
DOSBox-X was modified to always render per scanline regardless of VGA/SVGA machine type. There are a few things in the demoscene that require the ET4000 emulation AND per-scanline rendering.

2 years ago Nope. If I change to "vgaonly" it's even worse. :-) (dosbox 07.4).
When starting the above demo, it immediately crashes dosbox-x after doing the soundcard selection. Other demos launch with the same DosBox config.
