    I stuck a paperclip down the slot and shorted the damn thing out. The levels are particularly dark, but the load times are now instantaneous. I just can't seem to get the PSP to do anything else which is a bit of a downside.

    Update: Many people seem disappointed that it's a swap hack. Personally I don't have any problem with it as it works great. We at PSP Hacks give our thanks to the PSP-Dev team for discovering and providing this exploit. For those who are having difficulty getting it to work, follow these simple steps:
    1. Download any homebrew app/game
    2. Load up the MSwap Tool
    3. Select the EBOOT.PBP you wish to use
    4. Select an Output directory
    5. Click "Generate files"
    6. You're now left with two directories - MS1 and MS2
    7. Copy the EBOOT.PBP from the MS1 directory to your first memory stick (MS) - X:\PSP\GAME\
    8. Remove the first MS and insert the second
    9. Copy the EBOOT.PBP from the MS2 directory into X:\PSP\GAME\"
    10. Remove MS2 and insert MS1
    11. Go to the Game menu on your PSP and select Memory Stick
    12. Select the PSP-Dev Launcher
    13. The moment PSP logo screen comes on, swap memory sticks
    14. Vola! You're playing homebrew on your 1.50 PSP!

      To make things a bit easier, I've found that you only need to create the MS1 stick once. That is, once you have the special EBOOT.PBP on the first memory stick, you don't need to recreate it every time you change the EBOOT.PBP on MS2. Obviously, the file on MS1 will report the wrong name, but whatever is on MS2 still boots. Tested with the PCEngine, GB emulator and the SNES emulator.

    I was really excited about this, until I read that it's a swaploit... some people are having it work no problem, but some people are having troubles getting it to load, having corrupted data on their mem sticks, etc.

    Just a note, this hack only works on the firmware version 1.50, which shipped with the PSPs. Sony has since released two updates, 1.51 and 1.52, and the hack does not work on either.

    I'm guessing Sony is going to repeat what they're doing in Japan with the version 1 firmware homebrew hack: make new legit games check and force the firmware updates.

      • I know that they do it in Japan for online games. Everyone has a charger, they have to charge at some point.
      • Installing the update is a manual process regardless of what power source you're plugged into.
        • Yes, but Japanese PSP games have started checking for the updated firmware, and refuse to run if it is not installed. So you bascially cannot play any new games unless you upgrade the firmware. That's why some people have bought 2 PSPs, one for homebrew, one for UMDs.

      If I learned anything from the Xbox, it is that once there is even the slightest soft-mod, no matter how hacky and contrived it is and even if it just supports one or two versions of the console, as time goes on, it will become less hacky, more user-friendly, and support more versions. There is currently a soft-mod for the Xbox that is in every way as good as a modchip. It supports all versions of the Xbox, it is easy to install, it is easy to uninstall, and it even has a toggle for putting the Xbox into and out of a modded state, so you can go on Xbox Live.

      What I am trying to say is that if there is even a tiny little crack that allows for soft-modding a PSP, people will push and push until the mod is so easy to install and so full featured, that your PSP will effectively be able to run any binaries you wish, with no hassle.

      It will take allot of time though. A word of wisdom: if the Xbox drops in price to $99 or cheaper, buy at least one. It will be worth it even if there isn't a single official Xbox game you care to play. The homebrew software makes the Xbox a must own, IMO. The media players and emulators alone make it worth $99.

        You might actually be right, but I think the plan is to sell lots of memory sticks, not PSPs per se.

        I'll bet Sony's profit on an MS is more than it is on the UMD games. I wonder what the ratio of profit on a single MS sale to profit (to Sony) on a game is. And, for that matter, I'll bet that the COGS on the PSP is more than $249. The money is in getting MS accepted. (Hell, I've spent more on memory sticks than I have on games...)

    • Given the fact that future games will most likely automatically update the firmware.. ( I wouldn't be in the least surprised if UMD movies do as well )

      I have to choose whether I want to -buy- more software for their system or just keep the flexibility of homebrew... and.. since either direction means not going back to the other.. homebrew pretty much comes out on top.

    This seems highly inconvienant.. I'm not going to play the swap-trick on a car trip or on the bus, it just seems impractical.

    Nice work on finding this flaw though, but.. I'll wait until something else comes out that will let me run a homebrew app off of the same memory stick on 1.5*

    Note also that Sony will probably be requiring firmware updates with future games, so unless you want to dedicate your PSP to homebrew, you're kinda outta luck until a non-'swaploit' comes out.

    We got to find a way to control the firmware on the PSP before much is accomplished.. Reflashing to 1.00 on US units would make homebrew a reality, but then there is the game firmware update issue. To solve this, maybe someone could create a 'grub'/'lilo' type system that could boot firmware 1.00 or 1.5+.
    • I was quite surprised when I found out I couldn't run any of the cool homebrew applications I found on the Internet after I updated to 1.5

      This might not be elegant, but it works, which is good enough for the desperate types like me.

    A lot of you have complained and complained and complained. Lets not forget that although this is a swap trick, it is however a step in the right direction. To clarify some things that a lot of you are missing

    NO EXCEPTIONS, no 1.51 no 1.52

    Another thing, on your 2nd memory card it will be reported as "corrupted data" for this exploit to work. There is nothing wrong with the file that's on the 2nd Memory Stick. All of this is listed on the developer's site or in the "tutorial" in the archived files.

    Please for the love of bob, give these guys props. I haven't seen any of you guys that are whining give anything to the psp scene besides "we want we want we want". It is being worked on and the hardware will be hacked. As everything else goes this will take a while it's not going to happen over night.

    I personally would like to thank all those involved in this release. It sets the grounds for future exploits 1.5x. . ect.

    I was able to hack my WinXP box to run linux by using a second hard drive. It was actually quite easy.

    1. Pull out the hard drive with WinXP (you should probably do this with the power off, but it's more fun with the power on)

    2. Plug in a fresh new hard drive

    3. Put in your Fedora install CDs and follow the prompts

    4. Play homebrew linux apps on your hacked box (Profit!)

    The best part is that if you ever need to use WinXP again, all you need to do is turn it off and swap the hard drives.

    I realize this is merely a swap hack, but it's a start. Someday, I hope to be able to make it so I don't need to be pulling hard drives, but that could take til like 1995. We'll see

    Remember those memory stick select [amazon.com] sticks? They basically shove two separate memory sticks into a single package, and add a small switch that lets you choose which one to use.

    This actually sounds like the one case where that might be preferable to having a regular memory stick.

  • seems like sony is always vulnerable to this. the original psx and the ps2 both had swap tricks, but of course they really didn't screw up like sega did with the dreamcast. I mean anyone with a cd burner could burn games and play both online (PSO, NFL2k1, etc) and offline. it is only inevitable though that no matter how great the security is, someone will crack eventually.
  • One concern I have with spreading around hacked firmware and methods for using it is that it may make it a lot easier for people to cheat in multiplayer online games for the PSP. I've heard of it happening on other consoles, and of course it's rampant on the PC.
