Hi, Why does VGA_StartResize(Bitu delay) in SVN have 50 ms delay by default? Apparently, when an application sets a mode such as 13h ("mov ax,13h", "int 10h") and int 10h returns the mode has actually not been setup yet even though an application will think it is. This delay seems to be why the demo …

Is there a reason why 15,16 and 32-bit color modes are disabled for output=opengl? If I remove the disabling code, at least 320x200 32-bit color mode seems to work fine. --- dosbox-0.74.orig//src/gui/sdlmain.cpp 2010-05-10 20:43:54.000000000 +0300 +++ dosbox-0.74//src/gui/sdlmain.cpp 2011-06-05 22: …

Using Dosbox 0.74 and machine=svga_s3, the mode 0x10F (320x200, 32-bit color) outputs with bad aspect ratio. Looks like the window is twice as wide as it should be. The following patch fixes it: --- dosbox-0.74.orig//src/ints/int10_modes.cpp 2010-05-10 20:43:54.000000000 +0300 +++ dosbox-0.74//src/ …

I only have memory addresses from dosbox (0.74) heavy debugger. The vector ball code is loaded after the plasma cube and you can alt-pause to the debugger right before or during the vector ball floor fade-in. The first time the uninitialized variable is read is at instruction 2720:0829 (mov bx,[bp- …

To get the vectorball effect working I had to not only move all the files to the root C:\, but also rename 2ndfix.exe to 2.exe (so I would execute C:\2.exe). The vectorball code appears to use an uninitialized variable on the stack. The stack also contains the full pathname to 2ndfix.exe so that …

Never mind. I looked at debug_gui.cpp and there's a line "resizeterm(50,81);". I guess that is supposed to adjust the terminal size to 81x50 characters automatically, but I have to do it manually. Then the debugger output is fine.

I'm trying to use dosbox debugger, but it's unusable because the terminal window is messed up. I compiled dosbox with --enable-debug=heavy on Linux (Debian Etch) and the terminal looks something like this after I press alt-pause: 150000: VGA:h total 100 end0128blank 012898) retrace (85/97) 0596 …

I'd like to use output=overlay, but my video card can't do UYVY. Could someone point out the piece of dosbox code I need to change to make the output have YUY2 byte order?
