Hi ,

I have been reading much on the setup of dosbox for imperium galactica 1, this is because I didnt get into the game way back and now I am enjoying it, well actually IG2 but since I have discovered how good that is I want to get IG1 working smoothly.

I have a respectable dual core system, my cpu cycles are at auto but I have tried doing ctrl f11 and f12 and that only made things worse, auto seems best. Anyway the sound occasionally stutters, Im using dosbox 0.7.3 and have tried IG1 with and without the patch but same sound issues in the cut scenes and maybe other places its just I am using the intro.exe as a test to try and smooth sound, I have messed with some settings that may have not helped but I was wandering if anyone who has got ig1 working with no sound issue could compare their dosbox config to my own and tell me where I am going wrong, I tried messing with the sound buffer thing and sampling rates as well.

# This is the configurationfile for DOSBox 0.73.
# Lines starting with a # are commentlines.
# They are used to (briefly) document the effect of each option.

[sdl]
# fullscreen: Start dosbox directly in fullscreen.
# fulldouble: Use double buffering in fullscreen.
# fullresolution: What resolution to use for fullscreen: original or fixed size (e.g. 1024x768).
# windowresolution: Scale the window to this size IF the output device supports hardware scaling.
# output: What video system to use for output.
# Possible values: surface, overlay, opengl, openglnb, ddraw.
# autolock: Mouse will automatically lock, if you click on the screen.
# sensitivity: Mouse sensitivity.
# waitonerror: Wait before closing the console if dosbox has an error.
# priority: Priority levels for dosbox. Second entry behind the comma is for when dosbox is not focused/minimized. (pause is only valid for the second entry)
# Possible values: lowest, lower, normal, higher, highest, pause.
# mapperfile: File used to load/save the key/event mappings from.
# usescancodes: Avoid usage of symkeys, might not work on all operating systems.

[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=16

[render]
# frameskip: How many frames DOSBox skips before drawing one.
# aspect: Do aspect correction, if your output method doesn't support scaling this can slow things down!.
# scaler: Scaler used to enlarge/enhance low resolution modes. If 'forced' is appended,the scaler will be used even if the result might not be desired.
# Possible values: none, normal2x, normal3x, advmame2x, advmame3x, advinterp2x, advinterp3x, hq2x, hq3x, 2xsai, super2xsai, supereagle, tv2x, tv3x, rgb2x, rgb3x, scan2x, scan3x.

[cpu]
# core: CPU Core used in emulation. auto will switch to dynamic if available and appropriate.
# Possible values: auto, dynamic, normal, simple.
# cputype: CPU Type used in emulation. auto is the fastest choice.
# Possible values: auto, 386, 386_slow, 486_slow, pentium_slow, 386_prefetch.
# cycles: Amount of instructions DOSBox tries to emulate each millisecond. Setting this value too high results in sound dropouts and lags. Cycles can be set in 3 ways:
# 'auto' tries to guess what a game needs.
# It usually works, but can fail for certain games.
# 'fixed #number' will set a fixed amount of cycles. This is what you usually need if 'auto' fails.
# (Example: fixed 4000)
# 'max' will allocate as much cycles as your computer is able to handle
#
# Possible values: auto, fixed, max.
# cycleup: Amount of cycles to increase/decrease with keycombo.
# cycledown: Setting it lower than 100 will be a percentage.

I do have the original discs btw, I also hope I have posted this in the correct place 😀 anyway thanks for reading, maybe I am asking to much with such an old game but it would be nice to get that sound issue soted out as the game looks fun and it slightly ruins immersion.
