Here's an icon that I've been using in a custom build. It's based on this icon by Jojo Mendoza (released under a Creative Commons License): http://www.veryicon.com/icon/png/Application/3D%20Cartoon%20Icons%20Pack%20II/Command%20Prompt.png I've put together a Windows .ico file and dosbox_logo.h file …

I've found a free Windows program that can create ascii-format PPM files to be used for the dosbox_logo.h file (after following @yhkwong's procedure): http://www.xnview.com/ I've had complete success with @ykhwong's procedure. Thank you!

Your icon is not that bad but isn't it too round at the edge? I prefer relatively sharper one. @ykhwong - Here's a Z: icon with a sharper edge. It more closely matches your logo file. I hope it may be useful! http://dl.dropbox.com/u/271144/Dosbox-Z-revised.ico And here's an image. The gray …

Thank you again @ripsaw8080. Your .diff file let me build an executable that includes the underline under mode mono in vesa* mode and the correct display of 512-character fonts. I'm very grateful for the trouble you went to for this.

Again - thanks, and thanks for your patience with a beginner. As soon as I get back to my development machine I'll apply the patch, and also study the vgaonly code in the hope of learning something for myself, instead of asking other people to tell me. (It would be a lot more efficient and would …

May I ask your help once again? In another thread, @h-a-l-9000 provided a fix for the missing underline attribute in vesa* and svga* modes. This fix breaks your patch for the 2nd font bank, because your patch applies to a part of the code that is now commented out. I tried applying your changes to …

As soon as I used the correct file, the underline appeared correctly. Thank you again. I'll certainly report any problems that might result, but it looks perfect now. Unfortunately, this fix breaks @ripsaw8080's fix for the display of the 2nd font bank. So I'll go back to that thread and beg for …

I finally see my mistake - I was working from the release 0.74 source code, not the current SVN version at http://source.dosbox.com/dosboxsvn.tgz. The release source code has only one VGA_TEXT_Draw_Line function, so I did the best I could, which was obviously wrong. I really did your message …

Here's a report, with thanks for your continuing help on this problem. 1. I edited the distribution source as I think you suggested. I commented out the block that begins: static Bit8u * VGA_TEXT_Draw_Line(Bitu vidstart, Bitu line) { and I uncommented the block that (in the original code) began: …

@ripsaw8080 - Your patch seems to work perfectly here. I had to apply it by hand, because the version of the source that I'm using (generously provided by @TeaRex from his own project) had different line numbers, but I seem to have got it right, because the 2nd font bank is displayed with normal …

The reason I want to use a vesa* option in my custom build is that WordPerfect (which is what is shown here) can switch between text and graphic modes, including VESA graphics if available on the hardware (or emulated hardware). So on my real hardware, I have WordPerfect running in text mode in mode …

In a different thread, I raised the question of the way DOSBox displays the 2nd font table on a VGA display. This thread is about the underline attribute that becomes available when the video mode is switched to "mode mono" (video mode 07). All hardware that supports the VGA specification (including …

Thank you for that patch! I'll apply it when I get to my development machine tonight.

Thank you again. If anyone finds the Windows tool, I would be grateful. It looks as if it should be easy to automate the procedure of adding the zeros and the commas. A macro in a good text editor or a word-processor should do it. I'll experiment and report.

Then perhaps this can be fixed in the distribution release, because DOSbox currently does not reproduce the behavior of the actual VGA hardware, which does NOT use the bold attribute when displaying any upper-256 characters.

Thank you - that pointed me to plenty of code that does the job. As far as I can see, there's no prebuilt application that does it.
