[RELEASE] Massive Format Information

[lmame]

I know it's just in case someone didn't see it and was still trying to figure out how it was working

[Drakia]

Welp, here's an updated and fixed IFO format. Just did this as I was making my IFO dumper (Re-writing it) so it should be correct for Mobs, and NPCs atleast.

After in-depth analysis of the CON format, I have these modifications to make:

Line number On/Off | Expand/Contract | Select all

1. BYTE[0x202] unused
2. WORD unknown                  // is either CCCC, 0000, 2C2C or 4D00
3.  
4. DWORD block_offset            // always 524 / 0x20C
5. DWORD lua_offset
6.  
7. DWORD init_count              // always 1
8. DWORD init_offset             // always 16 / 0x10
9. DWORD dialog_count
10. DWORD dialog_offset           // always 100 / 0x64
11.  
12. // NPC INIT BLOCK
13. DWORD init_lookuptable        // always 4
14. DWORD entry_id                // always 0
15. DWORD Command                 // always 3
16. DWORD Data                    // always 0
17. BYTE[0x20] condition_function // always "TA_checkRepeat"
18. BYTE[0x20] reward_function    // always a nullstring
19. DWORD str_id                  // referenced LTB entry always says "Root", though the actual number might vary
20.  
21. // DIALOG BLOCKS
22. DWORD[dialog_count] dialog_lookuptable // contains offsets to each dialog
23. : FOREACH (dialog_count)
24.   DWORD block_size
25.   DWORD entry_count
26.   :XOR( ( (BYTE)entry_count % 2 == 0 ) ? (BYTE)block_size : (BYTE)entry_count )
27.     DWORD[entry_count] entry_lookuptable // contains offsets to each dialog entry
28. : FOREACH (entry_count)
29.       DWORD entry_id
30.       DWORD Command
31.       DWORD Data
32.       BYTE[0x20] condition_function
33.       BYTE[0x20] reward_function
34.       DWORD str_id
35. : ENDFOR
36. : ENDXOR
37. : ENDFOR
38.  
39. // LUA CODE BLOCK
40. DWORD code_len
41. :XOR( (code_len % 2) ? code_len & 0xFF: (lua_offset+4+code_len) & 0xFF )
42.   BYTE[code_len] lua_data
43. : ENDXOR

As you can see, the init block always has only one entry, whose contents are constant. I also corrected block_count to dialog_count, and updated the XOR key for the Lua code block, as it was slightly off in Brett's original format. All assertions have been checked with a script and show 100% consistency in an Evo client. Hope this helps.

I remember running across some INIT blocks that didn't have 0 as the data in pRose files. The init block is just what to initially do, so in the case of all your files, it's load dialog 0 as NPC text. I think I saw some in pRose that started at dialog 53 instead of 0 (Or something like that, I don't remember the exact number). I'll run a script on it later to double check though.

[Rescudo]

Sure, thanks for your effort.

I found some .MRP file today I didn't even know existed. So I spent a whole 5 seconds of my life reversing it's incredibly hard format.

Line number On/Off | Expand/Contract | Select all

1. DWORD Unknown
2. LSTR ZMS
3. LSTR ZMO
4. LSTR DDS
5. BYTE[0x20] Unused

[Blah4]

And... where did you find it?

[Drakia]

3ddata\effect\effectmesh\
3ddata\effect\effectmesh\mrp

[Rescudo]

From the looks of the format, it connects the ZMS, ZMO and DDS and is used to combine the correct files into an animated, textured model? (Just an assumption.)

[Drakia]

Those last 0x20 bytes don't look so much unused. Looks like 8 DWORD's, the values do change from file to file.
