Small subset of a screenshot of Impulse Tracker

Screenshot of Impulse Tracker running in Dosbox, scaled to 2x normal size.

Text-based user interface

Small portion of the screen centered around the mouse pointer

Yes: 120 x 80 pixels (approximatively 15 x 10 characters), scaled to twice the original size

The image is used as an actual sample of a text-based user interface in a VGA-compatible text mode using a redefined graphic character set with EGA/VGA graphic cards, not to present the program in itself. It does not show any significant part or technology of Impulse Tracker. The screen has been selected because it shows the mouse pointer forced to use two different colors when it overlaps characters that use different foreground colors. Impulse Tracker is an obsolete program, its latest release was in 1999 and it doesn't run on modern computers. It's distributed free of charge and is not profitable to its original author. This image is a screenshot obtained using the open source program Dosbox. The only copyrighted item is the portrayed program in itself. It also contains only a very small portion of the screen: 120 x 80 pixels (approximatively 15 x 10 characters), upscaled 2x.

Very likely not replaceable, for several reasons: the technique depicted is an obsolete "hack" necessary to represent a "graphic" mouse pointer given the limitations and peculiarities of text modes in the old EGA/VGA graphic adapters. It is also specific to single-task operating systems (like DOS), because the program needed direct and exclusive access to the hardware registers of the video card. No modern program (either text- or GUI-based) uses similar hacks and they won't be able to have this level of direct and exclusive access to the video adapter on current multi-task operating systems. So this image is probably only replaceable by very similar others that will probably also depict old proprietary programs. An important feature of this image that makes it harder to replace is that it clearly shows an artefact of this technique: the mouse pointer is split into three colored bands.

The use of the image will not affect the value of the original work or limit the copyright holder's rights or ability to distribute the original. In particular, copies of the image can not be used to make illegal copies of the program (that is also distributed free of charge directly from the copyright owner).
