Hot Wheels Micro Racers SFP

[aaro4130]

Hey! I'm trying to look into this format but it's out of my level. Currently all I know is this about it :

header:

Code: Select all

long totalFileLength;
long marker1; //always 1
long unknown; //never the same
long marker2; //always 2
long unknown2; //always the same
long marker3; //always 3

I've seen filenames throughout the files, but can't find a file table, offset to one, etc. Looks like some files are .TGA and some are compressed with WTGA. The only information I can find on wtga is this : http://www.verycomputer.com/155_b0804d5 ... 4_1.htm#p1

I have sample SFP's at http://mmarchive.com/aaro4130/SFP if anyone can take a look for me. They're all <2MB each.

SFP is a chunk-based format.
You can export the resource according to ID.

Code: Select all

//chunk id 1 is file

//chunk id 2 is 1's sub chunk
//chunk id 3 is 2's sub chunk, is a image data chunk.256 color Palette format.
//chunk id 0xE is 2's sub chunk, is a string table. CString(null-terminator).
//chunk id 0xF is 2's sub chunk, is a string's offset table(offset to 0xE chunk).

//chunk id 4 is 1's sub chunk
//chunk id 5 is 4's sub chunk
//chunk id 6 is 4's sub chunk
//chunk id 7 is 4's sub chunk,  a string table.4 bytes alignment, zero fill not enough.
//chunk id 0xB is 4's sub chunk

//Basic Struct:
typedef struct {
DWORD   chunkSize;
DWORD   chunkID;
byte    chunkData[chunkSize-8];
}chunk;


typedef struct {
DWORD   chunkSize;
DWORD   chunkID;

Wow man! Thanks so much . Gonna see if I can find out what any of the sub chunks are, on top of the ones you already found.
