Some questions about usermaps...

Nuklear · Post by **Nuklear** » Sat Jun 07, 2008 2:03 pm

How big is the CON header in bytes of an usermap because I can't seem to find out exactly. I've tried Google, experimenting, and others.

Also, in the structure for the usermaps, shade45 mentioned that BLF header is 48 bytes while in this thread, it's mentioned that BLF header is always 68 bytes long. I'm confused now. Which one is correct?

Finally, what is CHMD header?

A con file header is 0xA000 bytes long.

Thank you very much. Can someone answer the other questions please?

From what I saw, it's not either 48 bytes or 68 bytes =/
In both the screenshots and usermaps, It's much bigger than that.

For Content the blf header is 48 bytes long. In actual BLF images the header is 68 bytes long.

The size of the header is the first 32-bit int after the '_blf'...

yeah the _blf is 48 bytes long, after that is the chdr header.

Thank you for the answers.

Shade, I've noticed that you use Hex Workshop. I've found out that you count 2 bytes as 1 byte because Hex workshops groups 2 bytes from other bytes.

So, for this reason I have to divide your length by half in structures because I use another hex editor that does not do this.

I don't know if you did this intentionally, but I believe a byte consists of 2 hex characters such as 0x00, etc.

Trust me its 48 bytes, it's like that in other editors to...

Really? How come one time I've looked it was wrong. I think it must be my mind because it was late last night maybe been seeing numbers wrong or wasn't thinking. xD

Thanks for your answers.

heh, i never noticed the chdr section =/ I just assumed that was a part of the _blf header. My bad xD

eh 68 I assumed they were both the same but you know what they say about assuming

After the GT, is that the xbox id or user id that kind of stuff?

Hello. I would like people to confirm the following offsets (all are in decimal):

map_id_1 - 53802
spawned_object_count - 53831
map_boundary_x_min - 53836
max_budget - 53864
cur_budget - 53868

Are the offsets correct? I've opened several usermaps and it seems like it's right. But, I want to know it's actually right.

Not technically... the location of the user map inside of the container varies...

Shade released his white paper...

How come it's right in 3 usermaps I've opened. And isn't CON always A000 like haxalot says.

And, I know that whitepaper. I'm studying it.

If not, how would I be able to find the location inside the CON file?

ProfileID is 8 bytes long and is at 881, DeviceID is at 1021 and is 20 bytes long.

I forgot to mention that the offsets are in 116kb files. I assume it's correct because it's right in 3 116kb usermaps I've opened.

Also, how come the max budget is too low? In Ghost Town usermap, it says the max budget is 205 when it's really bigger than that. I've tried switching endians, etc. What's the correct way to read it? C#'s ReadInt32 says it's way too big.

What does BLF actually stand for?
