    Hello.
    I've been trying figure out a way to extract a working PSX ISO from my legit PSone classics for about two years now for personal backup reasons.
    Just recently though I stumbled across a pre-existing PSP app that can already do this very thing! Named psxdecrypt by Dark_AleX in 2007.

    The only problem is that it was made for CFW 3.03 OE and only works for said CFW and has never been updated to work with anything else.
    My question is if someone here could make it possible to run this on 6.60 PRO-B10? The source is included when you download it so if anyone could try and update this to work with the latest kernel that would be more then appreciated! I’ve been going insane trying to find a way to back these up!

    I've not tried it but i wouldn't count on it working on PSX content from the PSN. User made eboots are one thing...Official Classics are probably another.

    But it was made for PSN PSX EBOOTs.
    Here is the description for it in the readme...

    Sorry...i didn't even read what it was, i just assumed it did what you said it did.

    That's not a tool to extract ISO's from eboots. It's a tool to allow PSN content to run off CFW. You're looking for something along the lines of popstrip...although like i said, i doubt you'll be able to extract ISO's from PSN content.

    Does no one know if this can be done (how to get psxdecrypt running or another way of getting the same results)?

    Or I'm I asking in the wrong place? :unsure:

    Yeah, I know another bump by me but hear me out.

    Before I go on I've done some more research into this program and I can confirm that it does do what I originally thought it did (after hearing what xist said got me doubting myself).

    I’m figuring it would probably be better to ask Dark_AleX himself about this question, so does anyone know how to get in contact with him?

    the app most likely to old
    the keys most likely have changed

    and the app may NOT work anymore

    it from 2007 and it now, 2012

    Yeah I know. That's why I'm saying it needs to be updated.

    I don't think that is possible. However, when you first run a PSN PSone game on CFW it will create a file called keys.bin. As long as you have the eboot, document.dat, and keys.bin you can play that game on any PSP with CFW (regardless of PSN account if any on it or even if it is your PSP). Also note that with recent Pro-B firmware you CAN use a custom document.dat file even with official PSN PSone games downloaded from the PSN store. So here is how you back them up. And before you ask: yes that is how PSN versions of PSOne classic games are pirated as well (when I said any PSP I meant ANY).

    1. Download the PSOne game to your PSP with Pro-B10 on it (with either a PS3 or MediaGo) if you haven't already
    2. Run the game and make sure it boots up (the title screen is far enough)
    3. Exit the game
    4. Backup all the game files in the game directory (eboot.bin, document.dat, keys.bin)

    Thanks, I didn't know about the keys thing but I have already backed up all my PSone Classics onto my external HDD.

    I still would like to have the ISO's of the eboots extracted as well so they can be played on the actual hardware or an emulator of choice.
    I'm surprised no one has tried to mimic Dark_AleX's method for doing this back in 2007. Has anyone looked at the source? If so does it look like it can be recreated to modern preferences?

    You ask why nobody's done it? I ask you why it needs to be done.

    Two stated reasons are backing up on the PSP, and PSX.
    Personally I think both are faulty approaches, and here's why.

    • PSP
      As stated if you grab the keys out of your PSP's flash you can keep the backups of your legit copies functional. Since this is easily possible for CFW users, why is there a need to rip the actual ISO out, which is not playable on the PSP in that format anyways? So why would anybody continue to update a complex tool to achieve an end that can be done easily by simply copying keys out of your flash? The phrase "rube goldberg machine" comes to mind when comparing the two approaches.
    • PSX
      The excuse that they're legal backups for use on the actual PSX hardware or an emulator doesn't really fly in this case, because it's not a PSX game disc you bought, you bought a license for ported content on the PSP (which includes the original game, and a wrapper and such). In the legal world (at least in the US), that's something different from getting an actual game disc (a physical medium prone to deterioration) and backing it up for play on the same system.

      If you want a legit backup for the PSX, backup a PSX version.

      Even from a non-legal standpoint this is true, as the official PSP/PSN versions of PSX titles are often modified in order to stop compatibility problems (which is why you don't need to fiddle around with POPSloader versions for them, like you do with actual PSX backups moved to the PSP).

    So WHY would anybody fiddle around with complex methods to backup stuff that, if for the PSX, aren't actual backups (both in the sense that they're modified from the game, and not along the same lines as personal backup copies), and if, for the PSP, will rneder the backup unplayable on the PSP unless you repackage it, which will actually lower it's compatibility with certain firmwares?

    They can just back up the EBOOT and they keys, and be done with it. If they want a PSX version, they buy a PSX version.

    "Well the PSP ones are just PSX versions originally" - The law doesn't always follow common sense.

    I bought the EBOOT so I own everything in that EBOOT.
    If I actually wanted to make 100% sure this was legal I would ask a lawyer, not unprofessional internet lawyers.

    There modified, how so? Is there a detailed write up on this somewhere?


    I wanted to know whether it would actoully be a complex job or not, from someone who is knowledgeable in this field and has actually looked at the source and can say for sure.
    I Figured it wouldn’t hurt to ask.

    Rydian's right you know....you don't own the eboot. You bought a license to use content provided by Sony, and that license has terms where you're not entitled to modify the content they provided. Not only can Sony remove any and all content at any time they like (rendering your license pointless) but the fact that it's digital effectively means that you don't actually own anything.

    I was answering your question (why it hadn't been updated) by bringing into question it's purpose. To give a related example there was a PSX emulator for the PSP, but that stopped being updated a while ago because of the ability to run PSX stuff normally coming about... in many cases there's tools that have not been updated in a long time because there's no need for them anymore. You asked why it hasn't been done, I ask you why it needs to be done.

    Things are, by default, not done. The default state of existence is nonexistence. Therefore, in order for something to be made (a tool, an update for a tool, etc.), somebody needs to make it. So the question becomes the motives for creating a tool. If there's a big enough need and it's possible, it's likely to be done... however if there's very low demand or need, there's little reason for it to be done.

    You don't need to be a professional to read US code. It's easily-avilable.

    In addition, this isn't some complex "first-party parent of daughter of the third-party" crap, the issue here is what type of product a purchase you've made actually is (definitions of which are easily-understood once read), and how it relates to personal backups and fair use (for which there's many guidelines on copyright.org, and example cases).

    False. You bought a license, not the eboot.

    http://www.law.cornell.edu/uscode/text/17/202
    You bought a license from Sony. The eboot is provided to you so you can make use of that license. Just like when you buy a copy of windows you're buying the license (the product key), and the discs are simply provided for your convenience. The distinction between products and licenses for products has existed for a while, it's just become clearer (and more important) with the advent of digital distribution. How many times have you "bought" a product before (or even without) downloading it? You can get Windows, production software like photoshop, games like minecraft... tons of things can be "purchased", yet you're only getting a license, you don't own the actual product.

    Software licensing. Shit sucks, we all have to deal.

    Alright I believe you, it's illegal.
    I guess no one likes talking about this regardless of its legality so I'll just drop the subject.
    Thanks for your answers.

    It's more like if we're not hard-asses some people don't listen, so people like me tend to be hard-asses by default to save time. :P
