Well.... the basic stuff looks like to work when using GCC for compiling. I placed a binary under the following address (http://www.irixworld.net/download/dosbox/
) for those who are interessted in this. After the key works again i was able to produce a sample configuration file which looks currently like this one.
# 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 to use for output: surface,overlay,opengl,openglnb.
# autolock -- Mouse will automatically lock, if you click on the screen.
# sensitiviy -- Mouse sensitivity.
# waitonerror -- Wait before closing the console if dosbox has an error.
# priority -- Priority levels for dosbox: lowest,lower,normal,higher,highest.
# Second entry behind the comma is for when dosbox is not focused/minimized.
# mapperfile -- File used to load/save the key/event mappings from.
# usescancodes -- Avoid usage of symkeys, might not work on all operating systems.
# language -- Select another language file.
# memsize -- Amount of memory dosbox has in megabytes.
# machine -- The type of machine tries to emulate:hercules,cga,tandy,pcjr,vga.
# captures -- Directory where things like wave,midi,screenshot get captured.
# 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.
# Supported are none,normal2x,normal3x,advmame2x,advmame3x,advinterp2x,advinterp3x,tv2x,tv3x,rgb2x,rgb3x,scan2x,scan3x.
# core -- CPU Core used in emulation: simple,normal,full.
# cycles -- Amount of instructions dosbox tries to emulate each millisecond.
# Setting this higher than your machine can handle is bad!
# You can also let DOSBox guess the correct value by setting it to auto.
# Please note that this guessing feature is still experimental.
# cycleup -- Amount of cycles to increase/decrease with keycombo.
# cycledown Setting it lower than 100 will be a percentage.
# 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.
# mpu401 -- Type of MPU-401 to emulate: none, uart or intelligent.
# device -- Device that will receive the MIDI data from MPU-401.
# This can be default,alsa,oss,win32,coreaudio,none.
# config -- Special configuration options for the device. In Windows put
# the id of the device you want to use. See README for details.
# 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.
# oplrate -- Sample rate of OPL music emulation.
# gus -- Enable the Gravis Ultrasound emulation.
# gusbase,irq1,irq2,dma1,dma2 -- The IO/IRQ/DMA addresses of the
# Gravis Ultrasound. (Same IRQ's and DMA's are OK.)
# gusrate -- Sample rate of Ultrasound emulation.
# ultradir -- Path to Ultrasound directory. In this directory
# there should be a MIDI directory that contains
# the patch files for GUS playback. Patch sets used
# with Timidity should work fine.
# pcspeaker -- Enable PC-Speaker emulation.
# pcrate -- Sample rate of the PC-Speaker sound generation.
# tandy -- Enable Tandy Sound System emulation (off,on,auto).
# For auto Tandysound emulation is present only if machine is set to tandy.
# tandyrate -- Sample rate of the Tandy 3-Voice generation.
# disney -- Enable Disney Sound Source emulation.
# joysticktype -- Type of joystick to emulate: none, 2axis, 4axis,
# fcs (Thrustmaster) ,ch (CH Flightstick).
# none disables joystick emulation.
# 2axis is the default and supports two joysticks.
# serial1-4 -- set type of device connected to com port.
# Can be disabled, dummy, modem, directserial.
# Additional parameters must be in the same line in the form of
# parameter:value. Parameters for all types are irq, startbps, bytesize,
# stopbits, parity (all optional).
# for directserial: realport (required).
# for modem: listenport (optional).
# Example: serial1=modem listenport:5000
# xms -- Enable XMS support.
# ems -- Enable EMS support.
# umb -- Enable UMB support (false,true,max).
# ipx -- Enable ipx over UDP/IP emulation.
# Lines in this section will be run at startup.
mount D "/CDROM" -t cdrom
Start the programm with ./dosbox /tmp" if would like to mount your temp directory under c:.
During playing with the inbuild capture (press ctrl+F5) function i hace recognized that the apps use a default 2x scaling. But disable this doesnt change anything speedwise, also playing with core cpu cycles and Frameskipping brings no improvement.
I can start some older games like stunt car racer, heros of might and magic2 or megaman but it looks without some optimization my 600mhz FUEL isnt fast enough.
