    Default Scorpus' Sony UMD/ISO/CSO Guide

    outdated... use the VSH menu to rip your UMD's



    Note: This guide was written by an old friend. I've made some modifications though

    Introduction
    This guide is intended to help both new and experienced users in dumping/backing up their own UMD discs. I intend to cover several methods of Dumping and Optimizing and if desired Compressing said dumps/backups. As I learn of alternate or better methods to do such a task I will update this guide to cover such information. I do not intend to cover very old methods for older tools and firmware, however I will do my best to accommodate users as I see fit or am informed of older methods.

    Items/Applications/Home-brew Used in This Guide.
    1 - Items - PSP with Custom Firmware, UMD Disc, USB Cable and PC (Not necessary for some tasks.)
    2 - Dumper - 3.52 M33 or Newer CFW or PSPFiler 5.x or other app's such as UMDumper, UMDripper.
    3 - Compressor - UMD Gen 4.00 or PSP ISO Compressor or YACC.
    NOTE: I will cover basic *nix/Mac OSX compressors at a later date. (For those who are looking ciso maybe what your looking for.)
    4 - Decrypter (For PSN Games) - NP Decrypter(View Post 2)

    Dumping/Backing Up The UMD
    Method 1 - Built in method (Requires a Computer)

    Insert the UMD Disc into your PSP, Press Select (Or Home) to bring up the VSH Menu. Change your USB DEVICE to UMD DISC. Enable the USB Connection and use your computer to copy "UMD9660.ISO" to your hard drive. (Look and Method will vary by OS.)


    Don't forget when you are finished to set your USB Device back to Memory Stick. Copy the ISO to your PSP's ISO Folder and it will show up under Game > Memory Stick. You will need to set your UMD ISO MODE to either M33 Driver or Sony NP9660 to play. Skip down for further instructions on how to do this or how to compress your iso.

    Method 2 - PSPFiler (Good For on the Go) or other app's such as UMDumper, UMDripper.
    You will need to download and "install" PSPFiler from this link. There are two versions, one for the 1.5 Kernel and one for the 3.XX Kernel. The 3.XX version is not for messing with flash0/1 and it will warn you of this. Don't worry just drop the eboot into the PSP/GAME/PSPFiler folder and run. The first time you run PSPFiler it will ask you what language you would like, select this language and press square to save. PSPFiler takes some getting used to and is a little awkward. I will warn you that the button to go back differs from menu to menu so just don't press anything I don't tell you to.

    After booting PSPFiler and selecting language, Press TRIANGLE, then press R1. It will ask you to name it. To keep this simple just leave the name at default. Press the D-PAD to the right to select ENTER and then press CIRCLE. From here it will copy the UMD to your Memory Stick, you must have enough space on your Memory Stick for this part. Remember UMD's can range upwards of 900 MB to 1.8 GB. The file by default will be in your ISO folder and ready to play. You will need to set your UMD ISO MODE to either M33 Driver or Sony NP9660 to play. Skip down for further instructions on how to do this or how to compress your iso.

    There are an increasing amount of tools avaliable todo this such as UMDumper and UMDriper, keep an eye out for these as well.

    Playing the Game
    I will cover Optimizing and optionally Compressing the ISO for people who have small memory sticks or alot of games in the next section. For now lets just play this thing!

    Copy the ISO file to ms0:/ISO/ . Its not a bad idea to give each game its own name if you have more than one. However this is not required. Before you can play the game you need to use a NO-UMD Driver. There are two to chose from and the Sony NP9660 driver has a 98% compatibility rating. The other choice would be the M33 Driver, use which ever gets the game working for you. This is enabled by pressing Select (Or Home) to bring up the VSH mode and changing UMD ISO MODE. The game will be located where other Memory Stick games are located.



    Optimizing & Optionally Compressing the ISO
    UMD Discs contain Firmware Updates that are no longer useful inside the ISO, removing this will save upwards of 30 MB of space. Additionally UMD discs contain Padding and Dummy data to maintain file placement within the UMD structure, this can be removed to save anywhere up to 500MB. I removed 400 something odd MB from GTA:VCS to change the iso from 1.5 GB to 1.1 GB without any compression.

    Why not just compress it? - Not all games do well compressed, especially racing games that have little read ahead and alot to read.... ahead. Many games can be cut 10 to 30% just by optimizing though most of the padding is nullified with compression. I will cover compression in a moment but lets just get to the quick fix for space. I will also cover addition methods and software in my second post. Audio and Video can be ripped out of a UMD by advanced users to save even more space. PSN Decrypter users also need to use optimization to get their newly decrypted ISO's down a reasonable size. Most PSN games worked well with compression.

    Optimizing Using UMDGEN
    Download and extract UMDGEN 4.00 or Newer. Run the program, Select Open and find your ISO. Click on the UMD Properties Tab and find the Optimize Button. Click Optimize and save your ISO by going save and choosing Uncompressed ISO. You can if you wish chose a CSO and compress it now, however not the point of this exercise. NOTE: These Images are cuts and will not appear exactly as they do on your pc.


    Compressing the ISO
    There are many tools for compressing iso's most of them based off ciso. For us Windows users I will be covering UMDGEN and PSP ISO Compressor to start. CISO/CISO Plus is available for unix/linux users and for mac osx users who are familiar with the darwin unix command line.

    UMDGEN is easy, download, install and run if you have not already from the previous step. You mind as well goto UMD Properties and Optimize to save 40 extra MB on your compressed ISO. Save this time using Compressed CSO.


    PSP ISO Compressor is very basic but it works, its not going to allow you to optimize but the padding/dummy files compress very well so no worries. I do still recommend using UMDGEN. Select Compress ISO > CSO, Select your file and hit convert. A console window will appear and compression will start. Place the CSO in your ISO folder. YACC is more advanced but not quite like UMDGEN is though it provides some minor extras from ciso plus. Follow the screen shot for a fairly simple CSO or check out the advanced tutorial for more information. Once again Place the CSO in your ISO folder.

    Advanced Topics

    Using NP Decrypter to Decrypt PSN Games into ISOs
    If you do not already have it on your psp download your game from the PSN Store or transfer from your PS3. I will be using Twisted Metal Head On as my example. Note that older firmwares will need the USB Version Faker to access either now and NPD has been tested on 3.90 and newer only. Download NPD from this link, copy the NPD folder to the ms0:/PSP/GAME/ folder.

    You will need to find your PSN Game it will be in a folder named after its game id. Rename the EBOOT.PBP to NP.PBP and move it into the NPD Folder. Go to your Game > Memory Stick Menu in the XMB and select NPEG-RV. Once it executes it will tell you how big the ISO will be and ask you if you would like to decrypt it. Keep in mind the game will come out of this anywhere up to 900 MB. You will need the freespace but we will manage the file size back down to where it needs to be later.

    When this is complete there will be a new ISO in the ISO folder. The name will be something like UCUS-98601.iso, this will not always match the regular gameid but this is okay. Once you are done jump to my first post on optimizing ISO's using UMDGEN. NPD decompresses the game and also restores the proper padding as it would have been on the UMD version. Twisted Metal HO was a 309 MB eboot, it comes out of this at 799 MB. Just removing the padding gets it down to a good 400 MB, not bad at all. The game does well compressed although I chose to use only compression level 1 which brought the game down to a 329 MB CSO. Dont forget to delete the old game folder and npd when your done.


    Using UMDGEN to remove unneeded components to make the ISO/CSO Smaller.
    For this part of the tutorial I will be using the Game Need For Speed Carbon: Own the City. Its one of those games that doesnt have more than 20 MB of padding and plays like crap compressed, however due to some games playing well compressed I will also compare file sizes with its CSO counterpart. Its an 853 MB ISO so what can we do about it without compressing it? Optimizing it only removes 68 MB of space and compared to the compressed original we only really saved 20 MB. If you have already played the game you dont need the Movies and if you hate the music you dont need that either so lets get rid of it. Below is a table of the file sizes achieved through out this test:

    Untouched ISO = 853MB CSO = 368MB
    Optimized ISO = 784MB CSO = 348MB
    Re-Linked ISO = 616MB CSO = 182MB

    182 MB is not bad at all, for games that play well compressed this is lovely, however through spoiling the joys of cutscenes and music we have saved ourselves 240 MB on a game that we don't want to compress. Not all games just have their PMF's AT3's and other files out in the open. There are ways to completly extract and rebuild an ISO for a game like Final Fantasy VII Crisis Core, I will link to this in the future. i chose NFS-C:OTC because it is very open file wise. You will have to ask or use your brain to find the files you want to relink. NFS-C:OTC uses PMF's for the cutscenes and .AUD for the music which is found under eatrax.

    Click to enlarge


    How To Relink and What It Does - Using the video/PMF's as an example we will choose the smallest cut scene and relink all the other cutscenes to this. This will basically remove all the other files. To the game they will appear to still be there and end up playing the file they have been ReLinked to. First you must find where the videos are. Click on the images above to see each step.

    Step 1 choose the file to relink to, right click on it and select "Use Selected File as Source". Step 2 select the file(s) to be relinked. You can do this one at a time or use the CTRL button to select each individual file at once. Right click and select "ReLink to Source". The files will be relinked saved the UMD as an ISO or CSO as needed. Copy to the ISO folder of the PSP and play as usual.

    FAQs / Troubleshooting

    Q: Why Dump/Backup a UMD, isnt this piracy? A: Depends on your definition of piracy, I however do not support the act of piracy. There are pros and cons to doing this (check next FAQ). There is nothing like loosing a game due to damage or the entire PSP. Having a backup will still allow you to enjoy the game.

    Q: What are the advantages and are there disadvantages? A: Speed and Portability are the big pros. Uncompressed games run faster from a genuine memory stick than from a UMD. A large memory stick allows you to carry one UMD but many games without lugging around the other UMD's. The biggest con is space, games can take from 300 MB to 1.8 GB.

    Q: When I try to play an ISO/CSO i get the following "Error - The game could not be started. (80020321)" A: On 3.71+ Press Select or on 3.60 or older Press Home. This will bring up the VSH Menu. Use the D-Pad to scroll down and change UMD ISO MODE to either M33 Driver or Sony NP9660.

    Q: My game runs choppy/slow! A:
    Short Answer, Using the VSH Menu set your CPU CLOCK GAME to 333/166 and use less compression. If this does not help don't compress it.

    Long answer, Games designed for UMD discs have their access routines optimized for the minimum expected read speed of the UMD Drive. While ISO games usually run faster than UMD's, CSO's take longer to read data from due to processor overhead during the decompress/read routines. If the game was meant to be compressed it would read ahead sooner, due to a lack of ram in the psp and the intended usage many games dont read ahead any faster then necessary. Racing games and any games that have alot of texture loading going on don't do well compressed. PSN games are typically modified slightly to account for their native compression.

    Q: Does compression amount affect the game performance. A: In reality yes, in practice barley. When running a compressed game make sure your CPU CLOCK GAME is set to 333/166 in the VSH menu. File size barley changes from settings 1 to 9 but a minor amount of performance can be squeezed by only using 1 whil sacrificing a few mb of space.

    Q: I downloaded a ISO/CSO and it wont work. A: Email the file and problem to Jack.Tretton@SCEA.ASS and he will call the police to solve your problem for you.

    Q: I copied my Playstation ISO to the ISO folder and it wont show up. A: Dumbass.... Thats a whole 'nother realm.

    Q: NP Decrypter wont work. A: Make sure you have the games EBOOT.PBP renamed to NP.PBP and moved inside of the NPD folder. This has been tested on 3.90 M33 and 4.01 M33 so far, there is a future possibilty that this utility will not work with the latest games.

    What UMDGEN does is simply dummy the update folder, delete 'boot.bin' and delete any dummy padding files in the ISO image.

    Even though it doesn't look like a lot of space, you will see the difference in space when you compress it. I managed to rip a copy of Madden 09 and shave off around 400 MB from the original file size by just doing this in UMDGEN.
