The 7th Guest: Graphics
The 7th Guest graphics and VDX video format: a directory of planned documentation for palettes, frames, decoding, image extraction and graphics modding.
This section organizes the graphics side of The 7th Guest: the files that carry visual material and the questions involved in decoding, inspecting, extracting and rebuilding it. Its article directory covers VDX headers and chunks, still and delta frames, palette changes, timing, indexed images and the relationship between foreground and background buffers.
For a graphics modification, the useful starting questions are which file owns the image, how that image is represented, and which playback assumptions must survive a replacement. The entries below reserve space for that research. They are clearly marked as planned until an actual explanation, evidence or reproducible example is published.
This catalogue currently has 42 entries. 0 are published; the remaining entries are planned documentation, not completed guides.
