There's a bug in this patch. In src/hardware/voodoo_interface.cpp, this: RENDER_SetSize(v->fbi.width, v->fbi.height, 16, vdraw.vfreq, 4.0/3.0, false, false); should be: RENDER_SetSize(v->fbi.width, v->fbi.height, 16, 1000.0f / vdraw.vfreq, 4.0/3.0, false, false); RENDER_SetSize() takes FPS as …

Not sure about which C++ version this is for. It might be for a relative new one. No, it worked like that since the beginning. This is the C++ standard document from 2005 for example: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2005/n1905.pdf cppreference.com also always marks things as "C++ …

Next, we need to resolve the OpenGL includes inconsistency between MinGW and Linux. I am using Ubuntu. If you are on different distro, you got to figure it out yourself to locate the system gl.h. $ cd ~/src/dosbox-3858 $ mkdir -p ./include/GL $ cp -vf /usr/include/GL/gl.h ./include/GL/ Ok, now we …
Fix for memory allocation check
Posted on 2020-05-03, 19:36
MEMORY::MEMORY(Section*) has a bug where it uses the throwing 'new' but then checks for null, which will actually never detect an allocation failure because an exception will be thrown. The attached patch fixes it.

Re: HDD image geometry detection bug
Posted on 2020-04-27, 21:12
Right. I was hoping there could be some safe autodetection for this so that when running dosbox in Retroarch the user can just select an image to mount in the GUI. It's not possible to specify a geometry by hand there, you just select the image file. I guess I could kludge this by having the user …
Re: HDD image geometry detection bug

Hm. So for existing images that were not created that way, what problems would arise if dosbox used the head count from the BPB without having to verify it with -size? In other words, what if the sanity check would check if the BPB head count results in a cylinder count that works out fine compared …

I'm not sure what the auto-detection you describe in PCem amounts to Oops, it's just file size based. It says so right on the label: https://i.imgur.com/xeqWoB9.png bximage itself tells me that the CHS of the image it creates is: CHS=20/16/63. So I guess that's either a bug, or it's expected that …

I used MS-DOS 6.22 running in PCem to partition and format the image. So "fdisk" and "format d:". PCem itself detected the image as 16 heads when adding it to the emulated PC's IDE adapter.

Unfortunately, I don't know which version of GCC is in use in this particular case. It's a buildbot that compiles a dosbox core for …

Yeah. The common image creation tools (like bochs or PCem) create images with that BPB, but they report to the user 16 heads. If I didn't look at the dosbox code, I wouldn't even know what the correct value is supposed to be.

Well, it's 16 heads: Copy code to clipboard 1 Creating hard disk image 'c.img' with CHS=20/16/63 (sector size = 512) But it only works if I lie and say that it's 32 heads using "-size" 😒

(This is with current SVN.) It is currently impossible to mount HDD images. A 10MB image for example created with bximage from Bochs using defaults and formatted with DOS 6.22 fails the sanity check in drive_fat.cpp: /* Sanity checks */ if ((bootbuffer.sectorsperfat == 0) || // FAT32 not implemented …

For the fluidsynth 2.1 support that I've added to a libretro dosbox core I'm currently working on, having fluidsynth output audio is not necessary. Instead you can make it render audio directly in the dosbox mixer buffer using fluid_synth_write_s16(). I added an FSYNTH dos mixer channel (like the …
