Extracted Data File Types
The files produced from segments.xlsx are byte-for-byte extracts from a supported game binary. Most do not contain a header, filename, dimensions, or other self-description. Their folder and faux-extension therefore describe how Bloodwych ReSource interprets the bytes.
The faux-extension is documentation rather than a new file format: renaming a file does not change its contents.
| Folder | Purpose |
|---|---|
data/ |
General game tables which are not graphical resources, maps, or sound. |
gfx/ |
General graphics and their companion tables: walls, floor and ceiling artwork, interface pieces, doors, objects, avatars, and similar resources. |
gfx-data/ |
Shared graphics-renderer and viewport tables used by several resource types. These are primarily extracted for decoding, validation, and documentation and are not normally presented as editable artwork. |
monsters/ |
Graphics and companion data belonging to a particular large monster: graphic blocks, component layout, picture offsets, colour grades, and palettes. |
maps/ |
Tower maps and their switches, triggers, objects, monsters, entrances, and related data. |
sfx/ |
Sound data. |
segments.xlsx uses the Type value as the folder name and DATA BLOCK FILE as the filename. The resulting name is normally Type/DATA BLOCK FILE.
| Extension | Meaning | Normal treatment in the Super App |
|---|---|---|
.gfx |
Raw Atari ST four-plane graphical data as stored by the game. It contains no dimensions or picture directory of its own. | Editable through graphical export/import tools. |
.offsets |
Big-endian word offsets locating individual pictures inside an associated .gfx block. This is the table that divides or selects pictures in sequential graphic data. |
Generated and validated when graphics are imported; not normally hand-edited. |
.positions |
Signed screen X positions, Y positions, or packed X/Y pairs used when drawing a picture or component. | Advanced editable layout data with a live preview. |
.heights |
Stored picture heights used by the strip renderer. In several routines zero represents one drawn line because the value is used as a loop count. | Normally generated or validated against imported artwork. |
.layout |
A packed, resource-specific mixture of component dimensions, positions, graphic bases, spacing, or mirroring rules which cannot be separated cleanly without changing the original layout. This replaces the ambiguous .renderdata name. |
Parsed into named fields and exposed through an advanced component-layout editor. |
.lookup |
A value-remapping table, such as view distance to graphic size or facing direction to a graphic variant. Unlike .offsets, its values are not necessarily byte positions in a .gfx file. |
Usually fixed when shared by the renderer; monster-specific lookups may be regenerated with artwork. |
.flags |
Bit or word values which enable rendering behaviour such as animation or mirroring. | Normally fixed or expert-only. |
.colours |
A monster's ordered selections from the master monster palette, used for colour grades. | Editable with palette-index validation. |
.palette |
Palette entries or groups of palette indices. | Editable with format and range validation. |
| Extension | Meaning |
|---|---|
.font |
Raw game-font data. |
.sound |
Extracted sound sample data. |
.block |
A fixed-size binary structure which has not yet been given a narrower file type. |
.locations |
Encoded map or game locations. |
.map |
One tower's packed map data. |
.switches, .triggers, .obj, .monsters
|
The corresponding fixed-capacity tower data block. |
All extracted files are ordinary binary files and can technically be changed. The Super App decides which files receive an editor and which are treated as read-only engine data. Shared renderer tables are kept in gfx-data/; monster-specific companion data is kept beside its .gfx file in monsters/.
The spreadsheet's extract_only action has a different meaning: it allows a useful sub-block to be extracted without replacing that exact source span with an INCBIN. It does not by itself mean that the data is editable or read-only.
