Hi everyone, I’d like to extract the CRP pack. Can you help me? It’s for private use. Thanks

Thanks mister, how do I use your code for extraction? Sorry, I'm a complete novice. (Cmd)

You can easily convert it to the qbms code.

##############################
get BaseFileName basename

idstring "CRAP"
get Version ushort
get CRPRStrLen ubyte
getdstring CRPResourceName CRPRStrLen
getdstring Dummy 0x5
get StrLen ubyte
getdstring TrackName StrLen
get ResourceCount uint32
get DataBaseOffset uint32

for i = 0 < ResourceCount
	get Unknown_0 uint32
	get StrLen ubyte
	getdstring ResourceName StrLen
	get MD5StrLen ubyte
	getdstring MD5 MD5StrLen
	get Unknown_1 uint32
	get ResourceOffset uint32
	get Unknown_2 uint32
	get ResourceSize uint32
	math ResourceOffset + DataBaseOffset
	
	string Name p "%s/%s.dat" TrackName ResourceName
	log Name ResourceOffset ResourceSize
next i

The first file is some kind of TOC, second are data and rest are PNG's with some metadata on start.

ok many thank's

I just tried the extraction using QuickBMS. I copied the code and created a BMS file; I opened it in Notepad, deleted everything inside, and pasted your code. Then I followed the standard procedure, but an error popped up and it wouldn't extract. I think I must have done something wrong, so could you please tell me how to successfully extract the files and convert the meshes to FBX or OBJ? Thanks again.

Which error popped up?

Extraction works as expected for Tokyo 1%002E1v.crp:

edit: got a structure from the biggest .dat file:
