sol_hsa is working on a very cool graphical upgrade for The Kilrathi Saga. As anyone who's worked on modifying games knows, revamping graphics can be much more work than it sounds, so the predominant method is to take advantage of different scalers and filters. The result is ddhack, which adds bilinear filtering to Kilrathi Saga versions of Wing Commander 1 (and probably 2). Coincidentally, this also works with the PC Gamer release! In addition to smoother visuals, this tweak also improves multi-tasking compatibility for the game. Sol is currently looking for testers to help improve the compatibility and implementation of the program. It's been demonstrated to work somewhat differently on Windows XP versus 7, and more test results would be appreciated. Download ddhack 0.2 here (40 k zip) and provide feedback over at Crius.net.
Usage: Copy to the application directory (next to the .exe). Play.
F6 toggles between bilinear (smoother) and nearest-neighbor (closer to original) filtering.
F7 toggles logo on and off.
ddhack is still at a very early stage, and may be somewhat unstable. It has been mainly tested with the 'kilrathi saga' wing commander 1, but wc2 should also work. If any other directdraw programs work, it's a miracle!
