changing dosbox settings.

[capheind]

I'm running recalbox on a pi 4. I had a dos game (return of the mutant space bats) which wasn't running very well so I tried changing some settings but they don't seem to take. I can change settings in retroarch, save them, and nothing seems to take. Despite saving them both in the core settings and in the override a restart sends the settings back to default. I also changed the cfg file but it doesn't seem to change anything. Any thoughts?

@capheind Hi
Have u test to up cycles by pressing Ctrl-F12 ? Each press up the cycles count of the emulator.

According to your dosbox version, it's "normally" possible to overrided dosbox.conf for a game..

For exemple you can bundle each game in a zip with its own dosbox.conf (only for games who need, other games will stay on the default).

U can go more far in the config and get S3 driver (present on win3x.org for exemple)
And then use it here
For azerty user, u can find a nice (the lightweight) keyboard driver which make your keyboard as it is !

[dosbox]
# language: Select another language file.
#  machine: The type of machine tries to emulate.
#           Possible values: hercules, cga, tandy, pcjr, ega, vgaonly, svga_s3, svga_et3000, svga_et4000, svga_paradise, vesa_nolfb, vesa_oldvbe.
# captures: Directory where things like wave, midi, screenshot get captured.
#  memsize: Amount of memory DOSBox has in megabytes.
#             This value is best left at its default to avoid problems with some games,
#             though few games might require a higher value.
#             There is generally no speed advantage when raising this value.

language=
machine=svga_s3
captures=capture
memsize=24

There are some other tweaks, like lower the sound quality.
I ve got good result by setting rate to 22050
here

[mixer]
#   nosound: Enable silent mode, sound is still emulated though.
#      rate: Mixer sample rate, setting any device's rate higher than this will probably lower their sound quality.
#            Possible values: 22050, 44100, 48000, 32000, 16000, 11025, 8000, 49716.
# blocksize: Mixer block size, larger blocks might help sound stuttering but sound will also be more lagged.
#            Possible values: 2048, 4096, 8192, 1024, 512, 256.
# prebuffer: How many milliseconds of data to keep on top of the blocksize.

nosound=false
rate=44100
blocksize=1024
prebuffer=10

and here

[sblaster]
#  sbtype: Type of sblaster to emulate.
#          Possible values: sb1, sb2, sbpro1, sbpro2, sb16, none.
#  sbbase: The IO address of the soundblaster.
#          Possible values: 220, 240, 260, 280, 2a0, 2c0, 2e0, 300.
#     irq: The IRQ number of the soundblaster.
#          Possible values: 7, 5, 3, 9, 10, 11, 12.
#     dma: The DMA number of the soundblaster.
#          Possible values: 1, 5, 0, 3, 6, 7.
#    hdma: The High DMA number of the soundblaster.
#          Possible values: 1, 5, 0, 3, 6, 7.
# sbmixer: Allow the soundblaster mixer to modify the DOSBox mixer.
# oplmode: Type of OPL emulation. On 'auto' the mode is determined by sblaster type. All OPL modes are Adlib-compatible, except for 'cms'.
#          Possible values: auto, cms, opl2, dualopl2, opl3, none.
#  oplemu: Provider for the OPL emulation. compat or old might provide better quality (see oplrate as well).
#          Possible values: default, compat, fast, old.
# oplrate: Sample rate of OPL music emulation. Use 49716 for highest quality (set the mixer rate accordingly).
#          Possible values: 22050, 49716, 44100, 48000, 32000, 16000, 11025, 8000.
sbtype=sb16
sbbase=220
irq=5
dma=1
hdma=5
sbmixer=true
oplmode=auto
oplemu=default
oplrate=44100

Good luck,
Personnaly, i ve installed dosbian in my pi for dosbox.
