How do I properly use an SC-55 with a modern iMac?

I am seeking some advice about how to properly configure a Roland SC-55 Mk II to work with DOSBox on my iMac. I have no problem with the software settings - this is purely about the hardware setup. For background, my current setup is as follows: 1. 2019 iMac – it only has one 3.5mm jack (I do not …

Re: New Performance Issue In Mac OS Catalina

I only ask because the SDL2 SVN build seems to be the first build where enabling vysync actually has an effect in macOS. It works great in some games (i.e Epic Pinball, Lemmings Chronicles) but horribly in others (i.e Lemmings 2, Warcraft 2) where it causes major slow downs and sound problems. As it …

Re: New Performance Issue In Mac OS Catalina

that's really odd. Maybe vsync is enabled? That one setting has a drastic impact in the benchmarks I have run, for example it reduced the Quake FPS from 220 down to 40 (SDL2 build) I get the same result with metal and opengl. It can also cause sound problems (stuttering and/or slowdown) but it’s …

Re: New Performance Issue In Mac OS Catalina

When you upgraded to Catalina you lost the ability to run 32-bit apps, and the 64-bit version of DOSBox 0.74-3 is significantly slower than the 32-bit version. Have you tried the 64-bit SDL2 daily snapshot build by Dominus? I use this on my i9 iMac and I can get 200+ FPS on the Quake benchmark and …

Re: Black screen and freezing in macOS

@almeath can you try this build? (edit: build removed, please use the SDL2 build in my signature) It's a several revisions old SVN built against SDL2. If that works, I can do more up to date ones in the future. Not only does that fix the problem, but the performance is far superior to the SDL 1 …

Re: Black screen and freezing in macOS

except it hangs when you return back if you use opengl right. I think the only thing we can do is try to debug it, to see where it hangs. Either with adding log messages or running an actual debugger. Yes, that’s right. The core issue is the freeze when switching back, but only with opengl. I will …

Re: Black screen and freezing in macOS

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/ …

Re: Black screen and freezing in macOS

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 …

Re: Black screen and freezing in macOS

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 …

Re: Black screen and freezing in macOS

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 …

Re: Black screen and freezing in macOS

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

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 …
