ROMDIR

radad · Post by **radad** » Sat Jul 07, 2007 10:47 pm

Does anybody have some information on the ROMDIR structure? I have this so far:

typedef struct romdir
&#123;
    char name&#91;10&#93;;
    short unknown1;
    unsigned short size;
    short unknown2;
&#125; romdir_t;

But what are the unkowns?
Here is a dump of my rom0:ROMDIR

Code: Select all

I think its actually:

Code: Select all

typedef struct romdir 
&#123; 
    char name&#91;10&#93;; 
    short unknown1;       // <--- Some kind of file 'type' 
    unsigned long size; 
&#125; romdir_t;

Here is the structure

struct romfs_dirent {
char name[10];
short ext_size; // Size of the extended info
int size; // Size in bytes
};

What is the extended info?

Look at the list of your ROM dump.

Name ? Size ?
---------- ---- ----- -----
ROMDIR 80 1584 0
EXTINFO 0 2028 0

The second entry is the extended info. It defines long names for the BIOS modules.
