Version 1.2 crashing at launch

[Shrapnel21]

Immediate crash on 2014 iMac running El Capitan, here's part of the report in the hope it will help. =)

Could you please run the following patched version? http://www.dirkwhoffmann.de/virtualc64/VirtualC64_1.2.1a.zip

If it still crashes, could you open the 'console' app and paste the output that is related to VirtualC64? The patched version prints special debugging information such as the following (to get the full details, you need to click on the small triangle in the output log):

01.11.15 16:26:19,585 VirtualC64[36027]: depthTexDesc = <MTLTextureDescriptorInternal: 0x610000001390> { arrayLength = 1; cpuCacheMode = MTLCPUCacheModeDefaultCache; depth = 1; framebufferOnly = 0; height = 910; mipmapLevelCount = 1; pixelFormat = MTLPixelFormatDepth32Float; resourceOptions = "MTLResourceCPUCacheModeDefaultCache MTLResourceStorageModeManaged "; sampleCount = 1; storageMode = MTLStorageModeManaged; textureType = MTLTextureType2D; usage = "MTLTextureUsageShaderRead "; width = 1202; }

Still crashing. I opened the console (first time I ever did, I'm relatetively new to OS X) and looked for Virtual C64-related info, but all I found was the same stuff shown in the crash report window. Sorry. =(

[dirkwhoffmann]

It should look like the attached screenshot...

It's important to know how the last texture descriptor looks like before the crash happens.

[Shrapnel21]

Apparently missing that voice. =P

And just found out there are thousands of system errors, almost makes me regret switching from Windows to OS X... =(

[dirkwhoffmann]

I think I can nail it down. Here is another patch:

http://www.dirkwhoffmann.de/virtualc64/VirtualC64_V1.2.1b.zip

If it still crashes, there should be some texture related output in the console window.

Regarding the system errors: You are right. Under the hood, OS X is not as polished as it looks from the outside. I.e., Apples Metal API is giving me a hard time (very different behavior on different macs, internal shader compiler errors etc.)

[Shrapnel21]

Is this what you're looking for?

01/11/15 18:17:14,768 VirtualC64[668]: Background texture: <MTLTextureDescriptorInternal: 0x7facbaf5f2b0> { arrayLength = 1; cpuCacheMode = MTLCPUCacheModeDefaultCache; depth = 1; framebufferOnly = 0; height = 0; mipmapLevelCount = 1; pixelFormat = MTLPixelFormatRGBA8Unorm; resourceOptions = "MTLResourceCPUCacheModeDefaultCache MTLResourceStorageModeManaged "; sampleCount = 1; storageMode = MTLStorageModeManaged; textureType = MTLTextureType2D; usage = "MTLTextureUsageShaderRead "; width = 0; }

[dirkwhoffmann]

Yes, that is what I was looking for. For some reason, when the emulator tries to grab your current desktop background image during initialization, it gets an image of size 0 x 0 which is an invalid texture size.

Let's try this one:

[Shrapnel21]

It runs, thank you! =)

Since we're on the subject, could I ask a couple of questions? =) 1) how come the font looks slightly 'squished'? 2) could we get a 'quick screenshot' key in the future? I run a retrogaming website and I'd love to use VirtualC64 to take snaps for my reviews. =)

[dirkwhoffmann]

Hmm, the squishing is strange. It might be a retina/non retina issue. Are you using a retina display? This is how it looks on my own laptop:

I created the image via File -> Save Screenshot

A 'quick screenshot' key should be no problem...

[Shrapnel21]

I'm on a non-Retina iMac, but I just tried and I can confirm that the font is perfect in saved screenshots. =)

Thanks again and keep up the good work! OS X is badly lacking in the emulators department and we really need great apps like VirtualC64. =)

[dirkwhoffmann]

fixed in 1.2.1 (which just went online)

Thanks for the great teamwork!
