Re: A DOS program to test OPL2 percussion (0xBD)

As I mentioned, if you disable XMS and EMS in DOSBox settings then you won't get the XMS error with RAC. I'm unaware of anyone else with problems creating an account on SourceForge, but perhaps you can contact the admins there to see what the issue is. There is a section of the forum named "DOSBox …

Re: A DOS program to test OPL2 percussion (0xBD)

Please use an SVN build of DOSBox, as it appears that the DRO capture issue has been previously reported and a fix committed: https://www.vogons.org/viewtopic.php?f=41&t=38029 The RDOS Adlib Capture utility issue with XMS was also previously reported: https://www.vogons.org/viewtopic.php?f=33&t=5551 …

Re: Playing *.avi files in Windows 3.11

in Windows
AVI is a wrapper format, and many different codecs can be used on the contained audio and video streams. There are utility programs that will tell you which codecs are used in an AVI file. Installing VFW drivers (Video For Windows) in Windows 3.x allows decoding of many commonly used video …

Re: Text mode aspect ratio correction

You are apparently concerned less with aspect ratio than with the appearance of the text , because the first screenshot has corrected 4:3 aspect and the second does not. At the risk of repeating myself: In 0.74(-3) the pixel aspect ratio of text modes is intentionally forced to 1.0 in order to avoid …

Re: replacing Z Drive contents possible?

You have to *execute* an alternate shell (command interpreter) in order to replace DOSBox's internal shell, and I don't see you doing that in your example. You can use the COMMAND.COM from MS-DOS 5.0 or 6.22, but to use the one from 6.22 you must first use the command "VER SET 6 22" to change the …

Re: Text mode aspect ratio correction

In 0.74(-3) the pixel aspect ratio of text modes is intentionally forced to 1.0 in order to avoid interpolation, because the interpolated symbols can look quite ugly on lower host resolutions depending on output method. However, with the prevalence of higher host resolutions now, SVN does correct …

Re: Why always 256 MB free?

The default of 256 MB for an hdd is a lot of free space for much of the DOS era, but not so much that it can cause poorly-coded software to have numeric overflows or so when calculating. It's just an amount reported to satisfy typical free space checks, it's not actually tracked (increasing and …
