Except that a real VGA doesn't use exactly 70Hz either in Mode 13.
Re: Running Windows app from DosBox (This guy must be mad !!!)
Posted on 2011-05-21, 20:45
Things running inside DOSBox cannot communicate directly to the outside system, but you can do it indirectly. For example you can create a file with a specific name in a specific place whenever you want the outside program to do something. Then you'd need to run a program in the "outer" system that …
Re: Using arrow keys to emulate keypad/joystick?
Posted on 2011-05-21, 20:37
the C64 joystick is [...] a digital joystick that registers movement in four directions. The standard PC joystick is analog and operates very differently. While that is true, many PC games, especially early games that aren't flight simulators or similar stuff, don't need the "analogness" of the …
Re: Acessing Parallel port using Dosbox

It should, but I found it a bit of a hassle to correctly partition, activate and format a USB drive so DOS could boot from it.

Or a new EPROM burner. ;-) Generally, most desktop machines still allow installing DOS, or at least copying a working installation from another machine. Unless they use EFI instead of BIOS, or the graphics card is not VGA compatible, it should work. I've had good success with the DOS that's built …

There's a problem with the SVN addition. Wbat exactly is the function remove() in line 203 of midi.cpp supposed to be and where is it defined? VC++ Express 2010 gives an error along the lines of remove having only one parameter called "FileName", not three, so the function it is thinking of seems to …

I can only support what bloodbat has said: There was a time when I wouldn't have touched a Microsoft product even with a pair of pincers, but their newer compilers are quite good as regards performace of the compiled code, they beat even GCC 4.5 which is already quite a bit better than older GCC …

Personally I got executables of DOSBox that were faster than the standard downloadable version when using VC++ Express 2010 and tweaking all the optimization options. The 2010 compiler produces noticeably faster executables than the 2008. The difference is more pronounced when using the interpretive …
Re: Embed DOS program in DOSBOX install
Posted on 2011-03-17, 22:58
It's quite possible to compile DOSBox with all the libraries, except standard Windows libraries, linked into the executable. Look at the sdl-static project on Google Code, for example, for static versions of SDL & Co. Also you can turn off some things that require external libraries while linking …

It freezes when I (believe) I click things too quickly for my Intel 3 GHz cpu. By the way, this sounds quite unlikely. XP shouldn't ever crash because of CPU speed unless you have a real dog slow CPU (I mean well below 100 MHz or so) and I don't think you can even install it if your CPU is really …
Re: PC speaker problem
Posted on 2011-03-08, 21:25
Playing complex sounds (i.e. anything other than simple "beep"s) through the real PC speaker is next to impossible in a normal modern multi-tasking OS such as Windows XP, since unlike sound cards, the speaker has no hardware data buffer and thus is extremely timing sensitive. Access the real …
Re: BIOS INT14 error
Posted on 2011-03-05, 18:38
Well, *most* DOS programs with mouse support access the mouse through the standard INT33 mouse driver interface of DOS, which is the same no matter what kind of mouse (USB, PS/2, serial, bus mouse) there is. This driver interface is what's created by loading the MOUSE.SYS or MOUSE.COM program in the …

Instead of DOS 6.22, you could also use Windows 98SE, which contains a full featured DOS 7.1 inside it, in case you still have a 98SE CD around somewhere. In fact you can disable the loading of the Windows GUI in 98SE and use it as a "better DOS than DOS". Your IT people will be able to do that for …

Re: DOSBox BIOS Font
Posted on 2011-03-02, 16:41
If you're interested I've got a patch that makes the fonts look like those from a real IBM VGA card (except there's still no 9x14 and 9x16 specific character shapes for vgaonly mode, only the 8x14 and 8x16 shapes). IMHO they do look slightly better, e.g. if you type "MMMMMM" the M's won't stick …
Re: Type |more not working

You can use any real DOS directory you want if you need MORE and other real DOS commands to be available, I believe. Certainly MS-DOS version 5.0 and newer should work. Personally I use the one from Windows 98SE. Just mount the directory into any normal drive (i.e. not Z:) and set your PATH …

And you have to set up BIOS according to your DRIVE type - not according to the type of DISK. So with a 1.2MB drive you set your BIOS to 1.2MB, even if you want to use a 360K disk. Otherwise 1.2MB drives are compatible with 360K disks as long as you only use them to READ the disk. WRITING can give …

ProDigit, I guess if you'll code a good threaded version of DOSBox, the developers will be more than happy to accept your code.
Re: Type |more not working
Posted on 2011-02-19, 17:51
Even if you get a "more" program from another DOS, type file.txt | more won't work in DOSBox (without a real DOS booted) because the shell doesn't seem to support pipes. However, more < file.txt does what you want.
