| Independence Exploit |
| What is the exploit? The exploit allows the execution of homebrew programs on an unmodified ps2 by exploited a buffer overflow in the handling of ps1 game disks. It was initially discovered by mrbrown, and also goes by the name "Independence exploit". Back to top |
 |
| What does this mean for me? The ability to boot homebrew programs opens up a wealth of possibilites, from playing legitimately backed up games from disks as well as from an internal hard drive. There are also emulators for many systems, and even a few media players. Back to top |
|
| Ok, this sounds cool, how do I get started? First, you have to make sure that you have one of the older style(chubby) ps2's. Sony got smart and patched the newer slim consoles so that this exploit no longer works. Back to top |
|
| Ive got a compatible ps2, so what comes next? There are some more materials that you need(or probably already have). These include an original ps1 game, as well as a ps2 memory card(You cannot use a ps1 memory card for this) Back to top |
|
| So I've got all that, let's exploit. Not so fast, we need one more thing(theres always something, isn't there..) You need some way of getting some files to your memory card. The most popular methods are using Codebreaker or Action Replay Max in conjunction with a usb drive, in order to copy the gamesave.(Note, make sure that your version of either of these mentions usb drive compatibility) Not so common is using Gameshark, although some people have had luck with it, I don't recommend it. An alternative method would be to use either original swapmagic disks, or an original hdloader disk. Back to top |
|
| Ok so I've got one of the above, now where do I go? IF you have: ARMax + USB drive - go here Codebreaker + USB drive - go here Gameshark + USB drive - go here Retail HDLoader - go here Retail Swap Disks - go here Back to top |
|
| Sweet, I've got the exploit installed, but all I see is a screen telling me "Load LAUNCHELF.CNF Failed", what does this mean? This is nothing to worry about, it simply means that no settings file was found. uLaunchElf will automatically create this file when you change any of the settings. See my guides on using uLaunchElf here Back to top |
|
| Backups and swapping |
| What is a TOC disk? A TOC disk is used when swapping disks, and must be a retail copy of a ps2 game. The size of the files on the TOC disk must excede the size of the files on the backup in order for the backup to load properly. Back to top |
|
| I used my (insert ps2 dvd game) disk as a TOC to try and boot my backup of (insert ps2 cd game), and it didn't work, even though it was bigger in size, why? Woah, this won't work, the TOC disk must be the same type as the backup, so if your backup is a cd based game, you must use a cd game for a TOC disk.(most cheat disks are cds, not dvds) The same goes for DVD backups, you must use a retail PS2 DVD disk for the TOC. Back to top |
|
| Can I boot my ps1 backups using swapmagic/cogswap/zoneloader? No, if you want to swap backup ps1 games i suggest you purchase breaker pro, or use a ps1 gameshark and swap when it asks you to insert the game disk. Back to top |
|
| Misc. |
| What is an elf file? An Elf file is a program for the ps2, similar to an exe for windows. Back to top |
|
| What is the difference between a packed elf and an unpacked elf? A packed elf is compressed, and at runtime is uncompressed into ram, and loaded from there. Packed elfs are generally smaller in size then unpacked elfs, and can save large amounts of space on the memory card. It is very similar to UPX compression for exe files. Back to top |
|
| I want to make my own elf, can you give me somewhere to start? First off, make sure you are competent in the c programming language. Then head on over to http://ps2dev.org to dowload the compilers as well as sample code. Back to top |
|
| What is an IRX file? An IRX file is a driver for a device on the ps2, such as the memory cards or the controllers. It is comparable to a .dll file on a windows computer. Back to top |
|
| I want to watch my video files on my PS2, how can I do this? Download the excelent SMS Media Player created by EEUG. This application is actively developed, and features are constantly being added. This is definitly the "BEST" media player available for the PS2. SMS Downloads SMS User Manual Back to top |
|
| You mentioned emulators, what are the best emulators availiable for the ps2? The best emulator is probably pgen, which is a sega genesis emulator. It supports reading of rom files from the memory card, usb drive, as well as the hard drive(if you have one). It is a bit hefty in size if you are going to put it on your memory card, but its worth it if you like your Sega games. The second best emulator is SNES Station. As you probably guessed, it plays Super Nintendo roms. Not very well, but it does work. The "official" version only reads roms from a cd, so if you use it you will need either a modchip or to create a special cd and use mcloader; or, you can just download one of the hacked versions supporting rom loading from the hdd, as well as usb drives.

|
| What is my ps2 version? Your can find what version your ps2 is by visiting this site: http://www.mod-chip.com/en/ps2version.htm Back to top |
|
| I downloaded some gamesaves from the internet, how can I use them on my ps2 without having the actual program(armax/codebreaker)? Follow this guide I have written, and it will show you how to do just that. Back to top |
|
| How do I make an IPCONFIG.DAT file? mmmm writing this later Back to top |
|
| uLaunchelf |
| I downloaded uLaunchElf, and there are a ton of files, which one(s) do I need? The only file that you need from the uLaunchElf archive is BOOT.ELF. 'uncompressed_BOOT.ELF' is an unpacked version of uLaunchElf, and generally not needed, the rest you can safely ignore. Back to top |

| more stuff to come eventually Back to top |
|
| HDLoader | |
| What hard drives are compatible with my ps2? There is a very good hard drive compatibility list which you can find:http://ps2drives.x-pec.com/ Check it to see if the hard drive is compatible. Back to top |
|
|
|
| Help, My game doesn't work! Check the excellent compatibility list over at http://list.ps2hd.com to see what modes your game may require. Back to top |
|
|
|
| The compatibility list says that I need modes 1 and 3 for my game to work, how do I set these? Highlight the game in hdloader, and press select on the controller, from here you will be able to enable/disable modes Back to top |
|
|
|
| OK, so I see the list of modes in HDLoader, but none of them say "Mode 1" or "Mode 3", which ones do I set? With the more recent versions of hdloader, they have added more descriptive names for the compatibility modes, so they are now as follows
Back to top |
|
|
|
| Will I have to set the modes every time I reset my PS2? Of course not, the settings you select for each game are stored on the hard drive, and should only change when you choose to modify them. Back to top |
|
|
|
| The compatibility list says that the game I want to play requres MDMA-0, what does this mean, and how do I enable this? This refers to the speed that data is transfered from the hard drive. MDMA slows down hdd access closer to the speed of the dvd drive UDMA allows for faster hdd access, which may reduce load times even more, but also breaks some games. To take advantage of these different speed settings, you used to have to have a seperate hdloader elf file for each different speed that you wanted; this is no longer the case, as the more recent versions have a speed selector built in. The speeds are selected at the splash screen by holding down a button. The list of speeds and buttons is below.

|
| Can I install ps1 games to the hard drive? No this is not possible, and probably never will be, for reasons I may eventually explain here. Back to top |
|
|
|
| How do I add more games to my hard drive? To add games to the hard drive, you have three options: 1)Insert the game disk when hdloader is running and press install 2)Connect your PS2 to your pc over the network and use hdl_dumb/dump 3)Connect your ps2's hdd to your pc(either internally or externally using a hard drive enclosure), and use the program winhiip to add the game. Back to top |
|
|
|
| Is there a guide or something for using hdl_dumb/dump? Of course, and it was written by yours truly. Read it here Back to top |
|
|
|
| Im really, really noob at this, can you explain how to install a game using only the ps2? sure, this will get written later Back to top |
|
|
|
| Ok, thats too much wear and tear on my laser, and the network is too slow for me, how do I use winhiip? well you sure are the noob arn't you...lol, maybe later Back to top |
|
|
|
| Can you please tell me how to change the background and splash screens for hdloader, they are terrible looking? Turns out I have a guide for that as well. Back to top |
|
|
|
| Can I play online from the hard drive? No this is not possible because of DNAS protection. Back to top |
|
|
|
| But I saw DNAS patches, what are they for? The DNAS patches are for cogswap/swapmagic/modchip users so that they can get their backup copies to work online. Back to top |
|
|
|
| I extracted a game from my PS2 hard drive using winhiip, but the image is smaller on my pc drive then it was on my ps2. Why? This is due to the fact that each game is stored in its own partition on hdloader, and each partition has to be a multiple of 128mb. So for instance if I have a game that is 1974mb in size, when installed to the ps2 hard drive it will consume 2048mb of space, the closest multiple of 128 greater then the actual size. This is completely normal and is nothing to be worried about. Back to top |
