DOSBox-0.73.conf
PHP Code:
#    cycles: Amount of instructions DOSBox tries to emulate each millisecond. Setting this value too high results in sound dropouts and lags.
cycles=12000 
Now it takes 5mins from the moment I start the DOSBox to actually playing the game(includes ~ 2mins30seconds to load a saved game).

Also the gameplay speed is up to ~ 60% of the normal playing speed but the game sound is totally screwed up.
Is there a way to disable sound entirely in dosbox or fallout itself? that may help get you up to realtime.

Also, have youl tried playing with headphones plugged in? (this should reduce cpu overhead slightly by bypassing the software eq in pulseaudio used to protect the built in speakers)

I saw in Dosbox pages:
'With DOSBox 0.72, I am able to run Fallout smoothly with sound. You must disable the GUS support by specifying gus=false in dosbox.conf. Then run the sound.exe setup utility in the fallout root folder, and autodetect your soundcard. This should now recognize a SB. Test the sound then exit/sav.'

Maybe GUS emulation is tougher than SB, and above could help

Did anyone test this already?

Isn't that just for PC? because yeah, it works flawlessly on x86 builds, but remember that ARM must emulate every x86 instruction, so it gets way more slow. I think someone needs to optimize the emulation on ARM7 arch, possibly using some goodies included in Cortex8

Not really, Gravis Ultrasound is/was much more capable soundcard than Soundblaster. For sure GUS emulation is more complex than basic SB. When emulation is simpler, Dosbox runs faster.

By default Fallout/dosbox seems to use best soundcard available so better to disable GUS for faster emulation.

For sure Dosbox could get help if it also would be Cortex optimized but that may take some time.

uris, I was talking about speed of the emulation, fallout for sure doesn't run smoothly on n900 with dosbox. BTW GUS emulation is disabled by default.

Got fallout running , but its painfully slow and the touchscreen occasionally de-syncs. Has anyone figured out tweaks to get dosbox running any faster, would overclocking do much?
