can anyone pls make a texture exporter of Ridge Racer 7 text files:

It's a container. Table is in BigEndian. File count starts at 0x10 and offsets starts at 0x14.
I will try to make a bms for unpack RPT container and then noesis script for export R7T container.

O.K here's bms to unpack RPT. Just add *.dat extension to it.

Code:

############################
# Ridge Racer 7 tex unpack #
############################
endian big
get baseFileName basename

get Magic uint32
if Magic == 1380996096      # RPT
   getdstring dummy 0xC
   savepos baseOffset
   get files uint32
elif Magic == 1098015564   # ArcL
   get files uint32
   getdstring dummy 0x8
   savepos baseOffset
elif Magic == 1346454347   # PACK
   get files uint32
endif

for i = 0 < files
   if Magic != 1346454347
      get offset uint32
      math offset   baseOffset
      savepos tmp
   else
      get offset uint32
      get fileNum uint32
      get fileSize uint32
      savepos tmp
   endif
   goto offset
   getdstring dummy 0x8
   get fileId uint32
   getdstring dummy 0x18
   get size uint32
   math size   40
   string name p= "%s/%u.r7t" baseFileName fileId
   log name offset size
   goto tmp
next i

And here's noesis script tested on provided samples. Anyway there is one or meaybe more formats which uses ps3 swizzle. So those you must convert with Raw texture previewer/converter.

Code:

from inc_noesis import *
import noesis
import rapi
import os

def registerNoesisTypes():
   handle = noesis.register("Ridge Racer 7 - Texture", ".r7t")
   noesis.setHandlerTypeCheck(handle, noepyCheckType)
   noesis.setHandlerLoadRGBA(handle, noepyLoadRGBA)
   noesis.logPopup()
   return 1
        
def noepyCheckType(data):
   bs = NoeBitStream(data)
   if len(data) < 20:
      return 0
   if bs.readUInt() != 0x00543752:
      return 0
   return 1
   
def noepyLoadRGBA(data, texList):
    bs = NoeBitStream(data,NOE_BIGENDIAN)
    texBaseName = rapi.getExtensionlessName(rapi.getLocalFileName(rapi.getInputName()))
    texMagic = bs.readUInt()
    bs.readBytes(12)
    texPixelFormat = bs.readUByte()
    bs.readBytes(7)
    texWidth = bs.readUShort()
    texHeight = bs.readUShort()
    bs.readBytes(8)
    texSize = bs.readUInt()
  
    data = bs.readBytes(texSize)
    if texPixelFormat == 136:
        data = rapi.imageDecodeDXT(data, texWidth, texHeight, noesis.NOESISTEX_DXT5)
        texFmt = noesis.NOESISTEX_RGBA32
        print("Pixel Format > DXT5")
        print("Texture Width  >",texWidth)
        print("Texture Height >",texHeight)
    elif texPixelFormat == 134:
        data = rapi.imageDecodeDXT(data, texWidth, texHeight, noesis.NOESISTEX_DXT1)
        texFmt = noesis.NOESISTEX_RGBA32
        print("Pixel Format > DXT1")
        print("Texture Width  >",texWidth)
        print("Texture Height >",texHeight)
    elif texPixelFormat == 133:
        data = rapi.imageDecodeRaw(data, texWidth, texHeight, "a8r8g8b8")
        texFmt = noesis.NOESISTEX_RGBA32
        print("Pixel Format > RGBA8 PS3 swizzle")
        print("Texture Width  >",texWidth)
        print("Texture Height >",texHeight)
    texList.append(NoeTexture(rapi.getInputName(), texWidth, texHeight, data, texFmt))
    return 1

thank you so much brother. btw I've found i guess one broken yellow texture after extracting it. is it normal?

Yep, these are ps3 swizzled. You must use raw texture converter. Just open r7t file in raw texture converter and set offset 0x28 and don't forget to check ps3 swizzle flag.
This is what i get with raw tex conv.

Not sure about pixel format, but it's definitely 8 bit per pixel. I tried one of these and i get something like masks in channels.
And this is how it looks in photoshop.

Try to capture some textures with ninja ripper or any tool which can capture textures from PS3 emu.

EDiT: I updated my previous post. Bms now supports 3 formats of texture archive.
