[RELEASE] Massive Format Information

[xadet3]

They probably are used, but at the end of the day I have no idea what uses MRP so it isn't easy to find out, and I don't like to use the word unknown lol.

[Drakia]

They're referenced in EFT files

Damn you Brett, I leave rose for a couple years and there you go , you do all this stuffs I should have stayed around ^^ well good work

[Brett19]

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 don't entirely follow the purposing behind this. What the blocks "always" are doesn't matter, ROSE accepts the format with any correct value there, it doesn't have to be what it "seems" to always be. Also "(lua_offset+4+code_len)" == ( file_length ). <3

Cheers, Brett

Okay ... this information is more useful when you are making an editor I suppose, it's easier to follow the "always" values because you know they will work. But I see your point. Same goes for your "file_length", you do not necessarily know this value until you have actually made the file.

[timmehl]

well i had a nub server b4 but learning everything now 1st class of it so what can i basically do with this??

[Souleater]

Humpff ... due to the fact that you don't know what to do with this, well you basically can't do anything with it

I am sorry for putting it tthat way

Hello everyone! Can some one help me with .ZON format. I trying to read it but here:
// 1. DWORD blockcount
// 2. :FOREACH( blockcount )
// 3. DWORD blockid
// 4. DWORD blockoffset
// 5. :ENDFOR

I get those results:
blockid[0]=0; blockoffset[0]= 44;
blockid[0]=1; blockoffset[0]= 36936;
blockid[0]=2; blockoffset[0]= 37095;
blockid[0]=3; blockoffset[0]= 39253;
blockid[0]=4; blockoffset[0]= 45921;

As you can see blockoffset is too big, but it is read correctly, becose blockid has correct value. And when i trying to read section #2 i got wrong values and crash of the program can you help me to get through this problem?

PS
My english is bad

[Rescudo]

Those offsets are correct as far as I can see.

[Vel]

Correct? Maybe I have wrong type of block2:

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

1. struct  Data
2.     {
3.         float x;
4.         float y;
5.         float z;
6.         char name[8];
7.     };
8. struct Points // Points ( Respawn, Warp ) == 1
9. {
10.     int     entrycount;
11.     Data*   data;       
12. };

Is it right? I am not sure about name, what size it must be? Now i get first ~60 entrycount values = 0, and 61 is 16777216, I am sure this is not correct. This is my source, what is wrong?
