This method has been successfully tested and working with all currently released v6.20 games! (God Eater, Harvest Moon, Prince of Persia, Kingdom Hearts, Naruto, Modnation Racers, etc.)


How to Do It:

Tools you will need:

* eDecrypt, Prometheus & UMDGen
* The untouched, unpatched, not decrypted or modified in any way ISO. This DOES NOT WORK with a MODIFIED ISO.

1. Using UMDGen, extract the eboot.bin file from \PSP_GAME\SYSDIR.
2. Using UMDGen, delete the eboot.bin from \PSP_GAME\SYSDIR.
3. Using UMDGen, extract the libfont.prx file from \PSP_GAME\USRDIR\DATA\PRX.
4. Using UMDGen, delete the libfont.prx file from \PSP_GAME\USRDIR\DATA\PRX.
5. Using eDecrypt on your PSP, decrypt eboot.bin and libfont.prx. (Note: libfont.prx decrypting is only necessary for a few games, such as God Eater (J).)
6. Rename the eboot.bin you decrypted to eboot.old.
7. Using UMDGen, add eboot.old to \PSP_GAME\SYSDIR.
8. Using UMDGen, add eboot.bin & prometheus.prx from the Prometheus folder to \PSP_GAME\SYSDIR.
9. Using UMDGen, add libfont.prx to \PSP_GAME\USRDIR\DATA\PRX.
10. Using UMDGen, save as an uncompressed .iso.
11. Play!


Notes:

1. To work with Kingdom Hearts: Birth By Sleep (J), you must also decrypt BBS1.DAT, BBS2.DAT & BBS3.DAT and put the decrypted files in \PSP_GAME\USRDIR.

* To decrypt those files, you need dnas decryptor. (Now included in the tools download above.)
* Extract it to \PSP\GAME\dnas on your PSP Memory Stick.
* Put BBS1.DAT, BBS2.DAT and BBS3.DAT in the root of your memory stick.
* Run dnas decryptor. If it gives you a black screen, don't be worried -- it can take as long as 10 minutes to complete. When finished, it will put you back to the XMB automatically.
* When it's finished, you'll have BBS1_DEC.DAT, BBS2_DEC.DAT and BBS3_DEC.DAT in the root of your memory stick.
* Rename them to BBS1.DAT, BBS2.DAT and BBS3.DAT.
* Use UMDGen to put them back in your ISO at \PSP_GAME\USRDIR.

2. If you are an M33 user (WHY?!?!) you may also need to decrypt all the PRX files in \PSP_GAME\USRDIR\MODULES.
3. Make sure you are using an ORIGINAL, UNMODIFIED ISO!!


Tested and confirmed using:

ModNation.Racers.EUR.PSP-GLoBAL
Prince.of.Persia.The.Forgotten.Sands.EUR.PSP-GLoBAL
Naruto_Shippuden_Ultimate_Ninja_Heroes_3_EUR_PSP-ZER0
Naruto_Shippuden_Ultimate_Ninja_Heroes_3_USA_PSP-PSPKiNG
Harvest_Moon_Hero_of_Leaf_Valley_USA_PSP-PSPKiNG
Kingdom_Hearts_Birth_by_Sleep_JPN_PSP-Caravan
God_Eater_JPN_PSP-Caravan

I used GEN D3-Final, and my friend used the latest M33. Seems to work fine for both .. so M33 users are (unfortunately

Once you get used to the controls, I think it's very good. I don't have a PS3 to compare against though. The only thing I don't like is that it seems they're using "rubber band AI". All the computer players are always right behind you when you get hit, and it's very easy to go from 1st to 6th.

online doesn't work though,, connects signs in and then it gives an in game error and logs you out
Well the game isn't actually in stores yet.

You might need to use PSNLover to access the online, like with other online enabled PSP games?
He did say he signed in (Which you can't do without PSNLover IIRC) and that he got a in-game error so i'm guessing it's something to due with the Modnation servers not being open yet.

Uh, I know i'm going to sound like an idiot saying this but how am I supposed to decrypt eboot.bin from my PSP if it's stored on my PC...

eDecrypt is an application that runs on your PSP. You put it in \PSP\GAME\eDecrypt.

Make a folder on the root of your memory stick named "Enc". Copy the eboot.bin (and the prx files if needed) that you extracted from the ISO to the "Enc" folder.

Run eDecrypt on your PSP and let it decrypt all the files that are encrypted. It will save the decrypted files in \Enc\done.

Copy those decrypted files back to your PC to modify the ISO.

I know you're kind of kidding but Note 3 is kinda silly....GEN 5.50D and 5.00 M33-6 are all but identical, and what one gains over the other it loses in other ways. Freedom of firmware choice and whatnot compels me...

Edit - and by that i mean the bit in brackets if it wasn't immediately obvious!
