Trophy00.trp

Background

It is currently unknown what these are used for. Presumably something for storing information about trophy images/files

Structure

Note: This isn't complete.

typedef struct{
	u32 unk1; //perhaps magic?
	u32 unk2; //looks like version or something (3) 
	u64 filesize; //size of full trp file
	u32 entryCount; //num entries
	u32 unk3; //this could either be max entries or sizeof() entry...
	u32 unk4; //padding probably
	u8 hash[20]; //md5? sha1?  Could also be an IV for a form of encryption
	u32 unk5; // 0x30313000 ??
	u8 unk6[0x2C];
} trp_h

typedef struct{
	signed char name[0x20];
	u64 entryStart; //relative to &buffer
	u64 entryLen;
	u32 unk1; //3 on some, 0 on others, could be flags or an enum to determine if encrypted or not?
	u8 unk2[0xC];
} entry_t;

Entries

So far (from what I've seen) there are only 2 types of entries.

ESFM which are encrypted, and PNG which are not encrypted.

PNG is plain image data

ESFM is encrypted but seems to contain the same bytes at the top.

A digest? A Table? Encryption??

What do you think?

That's all so far ~Jakes625
