EA Sports' NASCAR titles (PS2)

Post by Scar7752 » Sat Jul 27, 2019 4:08 am

I'm looking for a few textures from EA Sports' NASCAR titles that were on the PS2.

Their archives are in a DAT file, which I know isn't helpful, but I wonder if a Madden tool could be reworked to work with these.

Here's a few files of interest from NASCAR 06, 07 and 09. They all run on the same engine so they should all work together in theory. I can upload more if you need more guinea pigs.

Would a QuickBMS script be of use to you? It will give you a bunch of .tmf and .3ds files.

I did this a while ago, but I think it works. I'm not an expert on textures, so hopefully you can do something with the extracted files.


# NASCAR DAT file extract

ComType EA_MADDEN

Get ARC_SIZE asize
Set CHUNK_START 0

Do
Goto CHUNK_START
Get CHUNK_NAME Long
Get CHUNK_SIZE Long

If CHUNK_NAME = 0x46524554
Get JUNK Long
Get JUNK Short
Get ENTRIES Long
Endif

If CHUNK_NAME = 0x31524944
SavePos DIR_START Long
Endif

If CHUNK_NAME = 0x504d4f43
SavePos COMP_START Long
Endif

if CHUNK_NAME = 0x41544144
Set DATA_START CHUNK_START
Endif

Math CHUNK_START + CHUNK_SIZE

While CHUNK_START < ARC_SIZE


For A = 1 to ENTRIES

Goto DIR_START
Get OFFSET Long
Math OFFSET + DATA_START
Get ZSIZE Long
Math DIR_START + 8

Goto COMP_START
Get COMP_FLAG Long
Get SIZE Long
Math COMP_START + 8

If COMP_FLAG = 5
CLog "" OFFSET ZSIZE SIZE
Else
Log "" OFFSET ZSIZE
Endif

Next A

I dug through some of the files and noticed that the 3DS files, when viewed in a HEX editor, start with "MMAP". Those are most likely textures then, right?

I'm not an expert on this side of things, but yes they do look like textures to me. The .tmf files may be the 3D models, but I wouldn't know what to do with either of those file types, unfortunately.
