SCI1, which is not covered by FreeSCI at the moment, introduces new concepts like Palettes, scaled bitmap images and several new compression algorithms. In SCI1.0, the resource limit was first increased to 16383 [1] , and then to 65535 in SCI1. Because of the inherent limitations of the FAT file system the primary target OS of Sierra's SCI interpreter was limited to, patch file names were altered accordingly, with the resource number (not padded) before the dot and a three-letter resource ID behind it; examples are "0.scr" or "100.v56".
The complete list of suffixes is as follows:
80: v56: 256 color views |
81: p56: 256 color background pictures |
82: scr: Scripts (static data) |
83: tex: Texts (apparently deprecated in favor of messages) |
84: snd: Sound data (MIDI music) |
86[2] :voc: Vocabulary (not used) |
87: fon: Fonts |
88: cur: Mouse cursors (deprecated in favor of v56-based cursors) |
89: pat: Audio patch files |
8a: bit: Bitmap files (purpose unknown) |
8b: pal: 256 color palette files |
8c: cda: CD Audio resources |
8d: aud: Audio resources (probably sound effects) |
8e: syn: Sync (purpose unknown) |
8f: msg: Message resources: Text plus metadata |
90: map: Map (purpose unknown) |
91: hep: Heap resources: Dynamic script data |
[1] | This appears to be the limit- none of the SCI1.0 games I tested used resource numbers beyond 16383 |
[2] | Type 0x85 resources are 'memory' resources, which are only used internally. |
