Convert US EUR monster hunter freedom 2 saves to JPN

Update: An alternative for the PSP slim is located here

All the files you’ll need – Download

Things to know before you start off

It took me several hours a day for several days to piece the whole procedure together, with the help of several friends. I’m doing this because I want to share my experiences/knowledge with the rest of the hunters in the world, nothing more. I expect the number of people visiting this site to increase over the course of this month as 2G is coming out, so if anyone feels helpful, do help out in any way you can in the comments. Like most people, I hate registration, floating adverts and rapidshare, so I’ll try to make this site as accessible as possible. If you have problems understanding my phrasing, do tell me so I can do amendments.

Japanese Monster Hunter Portable 2 = English Monster Hunter Freedom 2
.lbc files are actually text files which contain instructions and gamekeys to decrypt psp saves

There are a few reasons why someone would want to convert their hard earned US/EUR saves to the JPN version, or would even want to read this. If you have no tastes for theory, just skip all the way down to the practical part.

JPN version of monster hunter portable 2

– has more blood (technically I believe if you hurt a weak point, lots of blood will be spilling out. There might be a cwcheat for this, if anyone has it do tell me)
– it’s way cooler to play in japanese : D
– there’s an english patch available for the japanese version, it’s not 100% but you’ll get by
– last I checked, statistically, 25% of everyone who owns a psp in Japan has monster hunter, there should be more players on xlink kai

Okay, here we go~
Games which require firmware 2.0 and above most likely have the savegames encrypted, I would think there are 2 kinds of encryptions used, one which tells the psp to do the encryption, and the encrypts the savegame by game itself. For save games, there should be 3 different kinds of encrytion used, firmware 1.0, 1.5 and 2.0 above.

Monster Hunter Portable/Freedom 2 JPN/EUR/US uses 2.0 encryption, that can be decrypyed using a file containing the appropriate Gamekey.

Laboko is a japanese software, and they have most of the gamekeys for japanese games stored in Laboko’s boot.pbp file. The problem comes in when you need a gamekey for a US or EUR game like monster hunter freedom 2. You have to put the ULUS10266.lbc OR ULES00851.lbc into ms:/laboko/code/ (I would assume the extension means LaBoko Code or something, it’s not a usual extension that can be found)

We’re going to use Laboko to load save games from the memory stick and then convert an encrypted .bin to an unencrypted .bin file. With this .bin file, you can use a hex editor to modifiy your save games. THEN RENAME YOUR FILE TO ULJM05156.BIN. Afterwhich you use Laboko to convert your plain .bin back to the encrypted .bin. Since Laboko already contains the JPN gamekey, you can use Laboko to save your plain .bin to an encrypted JPN .bin!

Practical part
Laboko 101 – Download
ULUS10266.lbc – Download
ULES00851.lbc – Download
You will also need a JPN game save from somewhere online. Probably gamefaqs, I won’t be posting any JPN save files, cos they’re not mine and my own is just to embarrassing to show : D

If you have firmware 1.0 or 1.5, you should be able to run Laboko without any problems.

1.5 Kernel addon for M33 3.9 FAT PSP ONLY – Download

If you have custom firmware from M33, or you have problems getting Laboko to start, you’ll need to install the 150 kernel addon. A word of advice, if you’ve never flashed your PSP or are afraid of bricking your psp, you are better off asking for help in other places, sorry. Then again, you shouldn’t have any problems as I was on M33 3.71 R4, I merely followed instructions in the text file and viola, I can run Laboko : D

If you are using the slim, you will need to use the TimeMachine /w Pandora to load your slim into 1.5 kernel.

Also, you should try to have less than 5 saves on in your PSP’s save directory. From lurking I have heard that laboko doesn’t play well with more than 5 saves. So this might be one of the things choking up laboko.

After you run Laboko in the first time, a laboko directory will be created. Quit Laboko, and put the appropiate .lbc file into ms:/laboko/code and run Laboko again. I made the mistake of using the inbuilt usb in Laboko and I couldn’t convert the first time round.

You only need the correct one, so just download one.
ULUS10266.lbc << US Gamekey
ULES00851.lbc<< EU Gamekey

Follow the instructions which I ripped all over the internet and you’ll be on your way.

To convert your ENCRYPTED .bin to DECRYPTED .bin
> Menu 2 > Choose the US/EUR gamesave file > Menu 4 > Wait a few seconds > Viola




This shot here is actually wrong. It should show Monster Hunter Freedom 2nd on the left but the option is selected. This option does the decryption.

An decrypted .bin file should show up in the root directory of your memory stick.
– ULUS10266.BIN TO ULJM05156.BIN
– ULES00851.BIN TO ULJM05156.BIN

Yes I was a dolt, and I left this step out. Sorry. I assumed everyone knew how to read that part which says it’s missing the ULJM05156.BIN

To convert your DECRYPTED ULJM05156.bin to ENCRYPTED .bin
> Menu 2 > Choose the JPN gamesave file > Menu 5 > Wait a few seconds > Viola




You can now delete that ULJM05156.BIN you have in your root, or leave it there.

Load your JPN Monster Hunter Portable 2, see your savefile and ENJOY THE BLOOD!

In the next guide, I’ll teach you how to apply the english patch to MHP2 so you can have english menus!

Many many thanks to my Korean friend for providing me with BOTH the lbc files with the Gamekeys.

    where is the ULUS05051.lbc file?? DD: help!

  • kenshinjeff says:

    Sorry! There isn’t a ULUS05051.lbc, there’s only the ULUS10266.lbc

  • Zidanet says:

    Hmm. I think I’m stuck on the 1.50 kernel add-on part. I’m using 3.71 M33-2, and honestly I’m quite n00b when it comes to this kind of “tinkering with the system” stuff. And the 1.50 kernel’s instructions are like…. “Copy the files to this folder” and nothing else. Do you think you could help me on that one? I don’t want to bother you by asking you to convert my save for me so……

  • Kenjitsu says:

    Ok I do the first step. I did read your faq and it said i need a Hex editor? Reason im asking cause im getting problems at the second part.

  • KENJIXXX says:


  • kenshinjeff says:

    To install the 1.5 kernel on your system
    – Copy the whole UPDATE directory to MS0:/PSP/GAME/
    – It will look like this MS0:/PSP/GAME/UPDATE/
    – Start your psp, navigate to “1.5 kernel installer” and run it
    – Once installed, turn off your psp totally.
    – Turn it on while holding R, you’ll be able to switch to firmware 1.5 in one of the options there.
    – Voila
    – If you like you can delete the UPDATE directory

  • kenshinjeff says:

    Kenjitsu: Hi, you do not need a hex editor to edit anything.

  • oz78 says:

    what if the icon for the kernel installer appear as a corrupted icon? I hav read various guides and come to the point where I needed only to get this installer for the kernel to work. he 3.71files showed and ran but notified that it’s for 23.71(maning nothing has changed) eitherthe files i got from the site for dark alex is wrong or rapidshare hates me. I can never download off them.

  • kenshinjeff says:

    oz78: PSP fat or slim? It won’t work for slim, the kernel addon only works for fat. If it’s the slim you need timemachine 0.1. Boot to 1.5 with timemachine then run laboko.

  • oz78 says:

    fat 3.80 m33-5. I was unable to load the addon 1.50 as it is showing as corrupt data.

  • kenshinjeff says:

    oz78: I just downloaded it off darkalex’s webpage it unrars fine for me. I justed the old readme, it might work for you.

    Install instructions:
    – Copy the program to /PSP/GAME/UPDATE
    – If you have 1.50 addon, make sure you have the kernel of game folder configured to 3.71, or the program will not even start.
