Cryptogram Puzzle Tool helps solve the simple cryptogram puzzles that appear in the daily newspapers. While these puzzles can often be solved almost by inspection, CPT4 provides a handy tool the ones that turn out to be not quite so easy. If you just want a little bookkeeping help, CPT4 will instantly update all occurances of the new assignments as well as provide frequency and used/not-used letter lists as you drag-and-drop or key in suspected solution letters. But if you'd rather have the computer do the work, the automatic solution algorithm will usually come very close to a complete solution in just a few seconds. CPT4 can also create new puzzles from keyed in plaintext or from a file.
D1X is a modification of the Descent 1 source that was released by Parallax. It's mostly compatible with Descent 1 v1.5, both in multiplayer (new features/fixes may not work with standard Descent, but d1x will still work fine using the old methods) and on the local machine. D1x combines code from both D1DJGPP and ldescent (which are both now defunct/assimilated into d1x) and adds many features of its own. D1x runs on Linux (SDL, SDLGL, GGI, svgalib, and GLX), DOS, and Windows (WGL, DirectX, and Direct3D (incomplete)). In software mode, optimized renderers are available for Pentium and PPro/P2 computers, and OpenGL hardware acceleration is also available.
