Hardware scaling is already gone in newer cvs builds,
but you can use windowresolution= instead of it.

Thanks for the update, how does exactly this works?

windowresolution= variable?

size of the window you want.

ok now how do I type the desired dimensions, is it:
windowresolution=800*600 ?
and where exactly inside the dosboxc.conf do I add this line?
is it under [sdl] ?
or [render] ?
and does this works only with this month's latest builds or prior to the latest updates?

type inside DOSBox config -wc dosbox.conf to generate a new DOSBox configuration file.

Then, I assume is windowsize=WidhtXHeight
E.g. windowsize=800x600

What is the purpose of generating a new Dosbox configuration file?

The purpose is to see what new options are there and what sections they are in.

Awesome, I'll have a look & try out the new possibilities available,
thanks!

writing a new config is a MUST whenever you use a new version or if you are into CVS, you should do it once in a while. If you are using patched CVS it is even important to learn how to access new features.

Well, actually I'm not an advanced user, I managed to use the CVS updates, but now I'm a bit confused do I type config -wc dosbox.conf at the Dos command prompt?

No. You must type it inside DOSBox. Then, exit DOSBox and edit it using a text editor (like Notepad). The file is located inside your DOSBox folder.

I managed to resize to the window size with the latest CVS, Very nice, the new rgb2x & scan2x look impressive even though they seem to become innacurate when used with windowresolution=800x600, they look better when used 2x or 3x.
And something went wrong with the soundblaster emulation, human voices seem to fall down to low pitch for some reason.

I'm using a recent CVS build - ykhwong's 14/02/06 I think it is, and the pitch drops when the CPU is overloaded. Are you using that? I think it's an intentional modification to avoid the audio breaking up, though it makes things sound very weird!

I am using the latest CVS of Dosbox and I get the same issue, although I experience much less slowdowns in many games, I wish I could find a way to fix it tough. I am glad I can still use the hardware stretch, that was my primary concern so thanks to everyone who helped.

By the way you guys are awesome, I read the daily updates of Dosbox CVS, and you are doing some awesome work, to re-experience the dos gaming days with so much quality/enhancement/compatibility is a real treat! kudos to you all! 😅
