Recalbox 7.0: DosBox Slow


  • Revisor

    @RetroVadus What is your hardware?

    For me, DosBox runs also at same speed on v7 than on v6.
    But perhaps, the problem is due to RPI4.

    @RetroVadus What is your hardware?

    Raspberry pi 4 (1.2b) 4GB.


  • Revisor

    @RetroVadus Ok, great !



  • I have an RPI 4, but in the dosbox readme.txt file I can't understand anything, the only thing I understand is the name of the executable.exe there is no tutorial to create the .bat correctly and it is very complicated for newbies because there is no information


  • Revisor



  • I have downloaded a game and I still can't get the .bat that it includes to work is called play.bat I've renamed it to dosbox is this
    @echo off
    crack
    @echo on

    It does not recognize the game I have modified it like this:
    @echo off
    "c:"
    crack.exe
    exit
    @echo on

    He doesn't recognize it either, what am I doing wrong?
    the "c:" is put in quotes because if I don't get an emoji from the page



  • second try this is the dosbox.conf file of the game

    [autoexec]

    Lines in this section will be run at startup.

    cd ..
    cd ..
    mount c .\games
    #mount d .\games\lsl6\cd\ -t cdrom
    #mount d e:\ -t cdrom
    imgmount d ".\games\adark1\cd\alone in the dark trilogy cd 1.cue" -t cdrom
    "c:"
    cd adark1
    INDARK
    exit

    according to the instructions in this link https://recalbox.gitbook.io/documentation/emulators/computosaures/dosbox

    the dosbox.bat file should be like this:

    imgmount d ".\games\adark1\cd\alone in the dark trilogy cd 1.cue" -t cdrom
    "c:"
    cd adark1
    INDARK
    exit

    I've tried .pc and .dos still don't understand what I'm doing wrong



  • Hi again! A bit more of info regarded to the title of this post.
    After to change the key vsync to true in more games, not all the games worked correctly. For example, in the game Psycho Pinball the change was even worse. Changing this option can help in some cases but it is not the solution.

    Hope this help a bit.



  • the dosbox.conf of recalbox 7.0 is configured like this

    Vsync = true

    Because it does not work?



  • Dosbox on a Pi4, at the moment, will never perform better than on a Pi3 it seems. Others are also finding the exact same issue as yourself, and I found this :

    "it's to do with the framebuffer video driver included in the sdl1 library used by dosbox. The PI4 has a different kind of driver (it's basically emulated on top of the DRM/KMS primary video plane) which doesn't support resolution changing, as in the previous PI models.

    For the Pi3, the scaling might have worked with 2 methods - either the fbcon SDL1 driver did the scaling to a resolution supported by the framebuffer, or the scaling was done by using the SDL1 dispmanx driver (PI specific).

    The former is not supported anymore on the Pi4 - the latter works, but it's not 100% behaving the same as on a Pi3."

    Hope that helps.

    Thank you for the information. Not very goood news 😞
    Maybe updating dosbox but not secure. Current version in RB is r4290 and the lastest is r4378.



  • As another option more:
    If there doesn't seem to be a good solution soon, take into consideration to add optionally the core dosbox-X. It is a more advanced and vitaminate version of dosbox.
