Re: Yet another attempt at vertical sync

Posted on 2012-09-23, 13:38

Hi again, Another revision that can be tried out is attached. This may not exactly be what I've originally hoped for (a bit more than a week earlier), but it can still be tested. Changes: - The "vsyncwait" setting has been removed. - Somewhat more accurate timing is in use, especially when "framecap …

Re: Yet another attempt at vertical sync

For DirectDraw Change FullDouble to FullTriple simply by changing the BackBufferCount for the primary surface from 1 to 2 ( in DX5_SetVideoMode ) Instead of polling GetFlipStatus in a busy wait, simply return if the previous flip is still waiting to happen. (in DX5_FlipHWSurface) The problem is …

Re: Support for more than 4 buttons

Posted on 2012-09-01, 15:41

On specific situations (which are not too complicated), this should already be possible, although earlier knowledge of the way stuff was made to work would help. An example follows. Interestingly, you're not alone, njaydg: I also tested a 6-button gamepad with SSF2T (well the demo) long ago. A short …

Re: Yet another attempt at vertical sync

Here comes an update. Eventually, I haven't went by the way of *never* touching a hardware surface (or overlay) unless it is time to output something to the screen. The real issue might be when such a surface is the one returned by SDL_SetVideoMode (and similarly with the overlay). As long as VSync …

Re: Yet another attempt at vertical sync

Well, I've decided to give triple buffering a quick trial now... probably again. In my case, the following line has been added to the "Screen" section in /etc/X11/xorg.conf: Option "TripleBuffer" "True" For the testing, I've tried running vanilla DOSBox v0.74 on OpenGL with a couple of games, having …

Yet another attempt at vertical sync

Posted on 2012-08-22, 14:21

Please read this first: You should see a later post of mine (from 2012-9-23) for an update to the patch. Especially, it should be noted there is no need to play with the "fulldouble" and "vsyncwait" settings now. As for this post, I'm leaving its original contents for reference. Original post …

Re: Patch for OpenGL fullscreen bug

Posted on 2012-08-16, 16:19

Well, it has been a while since the last post. So what can be added for now... - First let's get back to the original topic: The OpenGL borders bug. So far, no actual patch (code-wise) has been posted, except for the first one removing a column and a row. So, I have attached a fix, which is an …

Re: Vertical retrace sync patch

Posted on 2012-08-09, 20:29

After a long break, here is a minor update to the patch so it is compatible with a recent SVN revision (3790). I have changed the default refresh rate to 60, as it is very commonly used with computer monitors these days. The patch has been tested on Linux with X11 only, and I cannot tell what would …

Re: Aladdin in slow motion movmement :(

Posted on 2012-07-04, 15:26

On the graphics driver side, the VSync setting should be the one for OpenGL apps (assuming there's any other). On the DOSBox side, set output=opengl or openglnb. One warning about VSync, though: If DOSBox takes advantage of a VSync setting like that, slowdowns are expected in some portions of some …

The link is dead. I searched hard on the internet, but I could not find it elsewhere. Could someone please re-upload it or give a working link? Thanks! In case of emergency, the Internet Archive may help :) http://archive.org/ The original site URL can be typed over there. Having some luck, the RAC …

Re: CGA Composite Mode under DOSBOX

Posted on 2012-06-11, 20:23

While I can't say that I really got to experience any composite mode on a composite display back then (although a built-in monochrome monitor accepting an NTSC signal was used)... Very good job over there! I can't say that I understand everything, and I'm sure you know what's done here better than …

Re: Descent II installation error

Posted on 2012-04-30, 07:30

Okay, I got it to work. I was using cdrdao which was making a .toc file instead of a .cue file. I used toc2cue to convert it, and mounting worked. I've installed Descent II, but there's one problem: the redbook audio is white noise. This has something to do with cdrdao I think. As far as this …

Re: DOS emulator help

Posted on 2012-04-07, 08:59

Well, it is faster for me with "spfix63 *0". So, I think it'd help if you tell some more info: - If you've still got the Supaplex download, is it a file named supaplex.zip with an exact size of 294017 bytes? (It'd be even better if you can check its md5sum is 50643570a58c8f13a79d49eab199aba8.) - …

Re: DOS emulator help

Posted on 2012-04-04, 22:32

Hmm... While I haven't really played a lengthy Supaplex session for some time... I recall the following command has made it (improperly) fast as I originally experienced it (and for sufficiently long time): spfix63 *0 With that, as you load a puzzle for the first time, it may be slow for less than a …

Re: Bio Menace 0.65

Posted on 2012-03-31, 20:36

Hey there, Bio Menace Episode 3 - Master Cain remains broken in DOSBox 0.74. I've tried the patch that comes with the game, and the two from this forum thread. Bio Menace Episode 3 - Master Cain hangs at the first screen showing which hardware is supported. It never moves past "Loading: Please wait …
