PS Vita Magic Reader v1.1

Post by PsDev »


A while back as a test I made Magic Reader v1 that extracted the Magic (SCEUF), the FW version and license.xml out of the Vita PUP. Well I just added a extraction for the whole Vita Header of PUP.
This script extracts the following:
[*]PUP Version
[*]Package Version
[*]Image Version
[*]File Count
[*]Header length
[*]Package length
[*]A Unknown bit of values 0x50 in length

Also later I'll add a FileTable extractor. which is determined by the FileCount.
This is a linux script and will run in any linux environment.

# PsDev 2012. this script extract the PUP magic.
#Edit from PsiColio lv1.self extractrion
#just extracts the header info from a vita pup, good for comparison kinda useless atm and most likely always.

# File names to extract from the PUP
Extract=( "Magic" "PUPVersion" "License.xml" "PackageVersion" "ImageVersion" "FileCount" "HeaderLength" "PakageLength" "UNKNOWN" "FileTable" "HashTable" "HeaderHash" )

#length starting from the offset and it ending in the offsets total length
length=( 0x8 0x10 0x724B4 0x8 0x8 0x8 0x8 0x8 0x50 0x20 0x40 0x20) #how many long the file is how much to copy, for example the Magic starts at 0x0 and the length is 0x8 bytes.

#offset of the Magic, Version and License
offset=( 0x0 0x9FF 0xC00 0x8 0x10 0x18 0x20 0x28 0x30 0x80 0x100 0x130 ) #where the file dump begins in the hex.


printf "____________________________\n"
printf " PsDev \n"
printf " Magic Reader \n"
printf "____________________________ \n\n"

for file in "${Extract[@]}" #tells it for a file look in Extract = the the file names


printf "____________________________ \n"

printf " %s\n" "${file}" #file name

printf "____________________________ \n"

printf "offset= %s\n" "${offset[$cont]}" #tells offset of file
printf "length= %s\n" "${length[$cont]}" #tells total offset length of file
printf "%s\n" "${cont}"

dd if=$1 of=$file bs=1 obs=1 skip=$((${offset[$cont]})) count=$((${length[$cont]}))

cont=$(($cont+1)) # make sure the usage is "./ PSP2UPDAT.PUP"

How to:
Make a new file named ""
Run "chmod +x" to give to execution permissions
Now in terminal run it. "./ PSP2UPDAT.PUP" It will output the three files in the folder/location the scripts located in.
Example out of the old Terminal LOG in v1, not updated there is a lot more files:

offset= 0x0
length= 0x8
8+0 records in
8+0 records out
8 bytes (8 B) copied, 0.0153084 s, 0.5 kB/s
offset= 0x9FF
length= 0x10
16+0 records in
16+0 records out
16 bytes (16 B) copied, 0.0528894 s, 0.3 kB/s
offset= 0xC00
length= 0x724B4
