Re: Black screen and freezing in macOS

Posted on 2019-10-11, 01:14

I don’t know if this is normal behavior, but whether or not I use 2560x1440, or 0x0, or desktop, I am finding that option-return takes me into what appears to be normal full screen mode, with proper scaling to the native desktop resolution. It appears to be the same whether I use opengl or surface/ …

are you compiling yourself? I have to test with my builds bit there was a problem when you compiled SDL on Mojave. My builds are done on OS X 10.11 which should work. Also latest svn in my sig No, I tested with the precompiled downloads on sourceforge. I will do some more tests with your SVN and …

Thanks for trying. Could you see if setting fullresolution=0x0 changes things ? (or fullresolution=your desktop resolution) It's somewhat unfortunate, as in 0.74-3 opengl is the default on Mac. I tried all of the same tests with the native screen resolution of 2560x1440 and also “desktop”. I then …

ah, so it is the switching back from fullscreen to windowed. Does the selected output have an influence ? Does 0.74-2 work ? (as that one is 64 bit compatible as well) I performed further testing in several versions of DOSBox, consisting of starting in windowed mode, switching to full screen with …

Does switching back to windowed mode work ? (so does going to fullscreen trigger it, or does shutting down from fullscreen trigger it) The freeze up will occur when: 1. Starting in full screen mode and then exiting DOSBox. 2. Starting in windowed mode, switching to full screen mode, and then …

Black screen and freezing in macOS

Posted on 2019-10-10, 03:01

I am not sure if this is a potential bug or just a problem that Apple introduced in the latest version of Mojave, so I would like to seek opinions. When I purchased a game from GOG using their DOSBox wrapper (Warcraft), I noticed that when exiting the application in full screen mode, a black screen …

Re: Apple's conversion to 64 Bit

There is also a 64-bit branch of Boxer that is being independently developed. https://github.com/MaddTheSane/Boxer/tree/updateDosBox It is possible that the original developer will come up with a 64-bit release this year, but he has been generally very quiet for the last 3 years. I have found the …

Tandy sound problem in 64 bit builds (macOS)

Posted on 2018-08-04, 17:23

I am experiencing a problem with Tandy sound emulation in the 64 bit SVN build of DOSBox for macOS. In two AGI games (King's Quest 1 and 2) with machine type set to Tandy, I am experiencing sound distortion that does not occur in the 32 bit 0.74 build with equivalent settings. Using King's Quest II …

Almeath, Oh no, I didn't intend to keep you from posting. I was merely trying to make a summary for myself. The mouse problem I am talking about is the yellow background around it. For your mouse problem, is that with a real mouse or a mousepad ? I have had unexplainable slowdowns with using the …

Re: DOSBox OS X built for OS X now 64bit

Posted on 2018-04-20, 12:44

I am sorry, I probably contributed to the confusion because I wrongly assumed that the sound stuttering problem I was experiencing was related to the 32/64 bit issue. Although it is now probably 'off topic' I just want to add for the record that the vsync patch definitely resolves the issue in both …

Regarding the slow downs: Unfortunately, you cannot expect one version of macOS to behave like any other. Each release needs to be tested individually ;). 10.11 is especially bad. I'm having the same problems, which have nothing to do with bitness, but with macOS restricting frame refresh. 10.12 …

Re: DOSBox OS X built for OS X now 64bit

Posted on 2018-04-19, 11:40

This got me thinking, so I re-installed 10.11 on my iMac and tested both the 32 bit 0.74 DOSBox and the 64 bit SVN by Dominus in each of 10.13 and 10.11. The results were rather confusing. In macOS 10.13: the audio slows downs occur in the 64 bit SVN but *also* under the 32 bit 0.74 release of …

Re: DOSBox OS X built for OS X now 64bit

No problem. I am glad to help. I think I further narrowed down this issue. I have found that when switching to windowed mode and moving the Mac mouse cursor rapidly, there is no slow down in the audio. However, clicking back into the DOSBOx window and repeating this with the DOS cursor does cause …
