use the turbo button (it's in the readme) I recall ctrl-alt-f12

The ReadMe says "ALT-F12 Unlock speed (turbo button)."

Hi!

In the readme it says alt+f12. I tried that and then pressed ctrl+f12 several times. Still, I'm left with 100% speed. Am I just not getting it?! Could be...

Set fixed cycles first, try cycles=20000 for example and use alt-f12 for the
passages where you need more speed.
But of course you won't get any program, not even dosbox, to run at more
than 100% of your real processor's speed.

and keep it pressed

Thanks. It works when I change cycles=20000 and keep ALT+F12 pressed. Is it possible to make it so that you don't have to keep pressing ALT+F12?

you would have to change the code of dosbox.
We like the keeping it press (it was designed to skip boring cutscenes)

andersryom, i don't really understand where your problem is. Your posts sound a bit like the joke with the "11" setting of the amplifiers from the "Spinal Tap" movie. I mean, "100%" is "100%" - it's a maximum value .

Anyway, the standard way of increasing the "CPU speed" in DOSBox is to increase the "cycles" value. Also, make sure the "core" parameter in dosbox.conf is set to either "auto" or "dynamic" (try both and see if it makes a difference). The maximum value of "cycles" is connected to the CPU speed of the host machine. If you set the value too high, your machine will begin to choke. Another fact to consider is that DOSBox uses a single core on multi-core systems, AFAIK.

If this information still doesn't help, you could try to explain what you are trying to achieve. This isn't completely clear from your posts. You should give some information on your system, too (CPU type and speed, memory, OS, etc.).

he wants to increase the timerspeed.

dosbox it's cycles=max tries to maximize the cycles while keeping the timers on the correct speed
alt-f12 tries to maximize the cycles , but intentionally increases the timer speed as well.

A joke?? It's not. Iøm just trying to make the games run faster as in the original settting. You use taht a lot in emaulators like WinVice (where you can see a maximum speed at a exact point, eg. 489 %), so I just thought you could use taht in dosbox as well.

Download ykhwong's build (http://ykhwong.x-y.net/cvs/frame.html)

It features switching turbo mode on/off by pressing <Alt gr> + F12.
