[cpu]
# core -- CPU Core used in emulation: simple,normal,full,dynamic.
# 			Try simple first as this is the fastest, then normal and last full
# cycles -- Amount of instructions dosbox tries to emulate each millisecond.
# 			Too low and the game will crash randomly
#			Too high and expect slowness
# cycleup   -- Amount of cycles to increase/decrease with keycombo.
# cycledown    Setting it lower than 100 will be a percentage.

[mixer]
# nosound -- Enable silent mode, sound is still emulated though.
# rate -- Mixer sample rate, setting any devices higher than this will
#         probably lower their sound quality.
# blocksize -- Mixer block size, larger blocks might help sound stuttering
#              but sound will also be more lagged.
# prebuffer -- How many milliseconds of data to keep on top of the blocksize.

[sblaster]
# sbtype -- Type of sblaster to emulate:none,sb1,sb2,sbpro1,sbpro2,sb16.
# sbbase,irq,dma,hdma -- The IO/IRQ/DMA/High DMA address of the soundblaster.
# mixer -- Allow the soundblaster mixer to modify the dosbox mixer.
# oplmode -- Type of OPL emulation: auto,cms,opl2,dualopl2,opl3.
#            On auto the mode is determined by sblaster type.
#            All OPL modes are 'Adlib', except for CMS.

# gusrate -- Sample rate of Ultrasound emulation.
# ultradir -- Path to Ultrasound directory.  In this directory
#             there should be a MIDI directory that contains
