The Really Useful SCUMM etc. Info File IndexFiles ---------- 00.lfl/000.lfl Used in V3/4 .000 Used in V5/6 .LA0 Used in V7/8 Conventions: ------------ All little endian unless stated Chunk - a named part of the file, ie RNAM Chunk sizes begin from the start of the chunk ie they include the 8 bytes for the chunk header and size *=repeat until *=no of items, then move onto the next * eg for DROO, read Room No until you've read in (No of items) then do the same for offsets #=do then move onto the next #item and loop until=no of objects eg for RNAM, read Room No, them Room Name, then loop Chunks ------ RNAM Room Names In V5+ MAXS Maximum Values In V5+ DROO Directory of Rooms In V5+ DRSC Direcory of Room Scripts In V8 DSCR Directory of Scripts In V5+ DSOU Directory of Sounds In V5+ DCOS Directory of Costumes In V5+ DCHR Directory of Charsets In V5+ DOBJ Directory of Objects In V5+ AARY List of Arrays In V6+ ANAM Animation Names? In V7 RM Room Names In V3/4 0R Directory Of Rooms In V3/4 0S Directory Of Scripts? In V3/4 0N Directory Of Sounds? In V3/4 0C Directory Of Costumes? In V3/4 0O Directory Of Objects? In V3/4 Scumm V5 -------- Files are xor'ed with 0x69 RNAM ---- Block Name (4 bytes) Block Size (4 bytes BE) #Room No (1 byte) #Room Name (9 bytes) XOR'ed with FF Blank (00) byte (1 byte) Marks end of chunk MAXS ---- Block Name (4 bytes) Block Size (4 bytes BE) Variables (2 bytes) Unknown (2 bytes) Bit Variables (2 bytes) Local Objects (2 bytes) Unknown (2 bytes) Character Sets (2 bytes) Unknown (2 bytes) Unknown (2 bytes) Inventory Objects (2 bytes) DROO ---- Block Name (4 bytes) Block Size (4 bytes BE) No of items (2 bytes) *Room Number (1 byte) *Offset (4 bytes) DSCR ---- Block Name (4 bytes) Block Size (4 bytes BE) No of items (2 bytes) *Room Number (1 byte) *Offset (4 bytes) DSOU ---- Block Name (4 bytes) Block Size (4 bytes BE) No of items (2 bytes) *Room Number (1 byte) *Offset (4 bytes) DCOS ---- Block Name (4 bytes) Block Size (4 bytes BE) No of items (2 bytes) *Room Number (1 byte) *Offset (4 bytes) DCHR ---- Block Name (4 bytes) Block Size (4 bytes BE) No of items (2 bytes) *Room Number (1 byte) *Offset (4 bytes) DOBJ ---- Block Name (4 bytes) Block Size (4 bytes BE) No of items (2 bytes) *Owner of Object (1 byte) ScummV6 ------- Files are xor'ed with 0x69 RNAM ---- Blank Byte(00) (1 byte) MAXS ---- Block Name (4 bytes) Block Size (4 bytes BE) Variables (2 bytes) Unknown (2 bytes) Bit Variables (2 bytes) Local Objects (2 bytes) Arrays (2 bytes) Unknown (2 bytes) Verbs (2 bytes) Floating Objects (2 bytes) Inventory Objects (2 bytes) Rooms (2 bytes) Scripts (2 bytes) Sounds (2 bytes) Character Sets (2 bytes) Costumes (2 bytes) Global Objects (2 bytes) DROO DSCR DSOU DCOS DCHR DOBJ ---- All as in V5 AARY ---- Block Name (4 bytes) Block Size (4 bytes BE) #Stop (2 bytes) Stops if 0x0000 #A (2 bytes) #B (2 bytes) #C (2 bytes) num=AARY no (itinerate through in loop) if c=1 then AARY=(num, 1, a, b) else AARY=(num, 1, a, b) If stop=0 you dont seek past the 6 bytes of A,B,C you just start the loop again.
