Help with extracting ISO from PS1 Eboot.PBP

[mynamesmouse]

Im not sure if someone is working on this yet. I was curious so I FTP'd over my PS1 PSN games and Ive been trying to extract the iso's. PSP tools do not work. Are they encrypted? Sorry if Ive sounded dumb but I need some help. Thanks.

I'm guessing with graf's new tools for npdrm decryption this now might be possible.

I'd really love to see a PS1 backup manager.

My hand is itching to try Legend of Dragoons again on my shiny ps3. I swear I played this game at least 5 times trying to get all the stardusts before I found a faq.

tryed to substitute the psn ffvii pbp with my original backup pbp to psp popstation to see what happens but cant find a way to encrypt again

I found this post in google's cache of pee ess 3 iso dot com before it blew up.

Okay well here is what I did, it is simple.

Download PBP Unpacker
Buy any PSX game off of psn and install it on your ps3. (Lets say Spyro)
Connect FTP and get the EBOOT.PBP File from the psx games directory.
Download an EBOOT.PBP PSX EBOOT PSP Game from pspiso.com of the game you want. (Lets Say Resident Evil)
Open the EBOOT.PBP of Resident Evil and extract all of the files to a folder and name it Resident Evil.
Now open the PARAM.SFO that is in the EBOOT of SPYRO and EDIT it if you like and extract it, overwriting the PARAM.SFO in the Resident Evil Directory.

Now choose to make a NEW PBP using all the files in your Resident Evil directory. You should be using the PARAM.SFO from Spyro to build it.

Now when you got your NEW EBOOT.PBP upload it to your PS3 SPYRO directory, overwriting the original (MAKE SURE TO BACK THEM UP!!!!)

Turn PS3 off then on again, launch SPYRO and it should work as Resident Evil.

If by chance this does NOT work, you may need to Edit TWO PARAM.SFO

1. In the Root Directory of your psone game on the ps3.
2. The PARAM.SFO that is injected into your EBOOT.PBP

The edit you want to do is change the DISK_ID to that of your Resident Evil (Which is SLUS00747)

You may also need to sign the file! Find that program.

Key here is you need to OWN a PSOne game to replace it!

Now I may have missed some steps here as I was trying a TON of different things, if so I am sorry.

I used this method to get Resident Evil DC working by using the Resident Evil Files to replace the Castelvania files in the EBOOT.PDP.

If anyone finds more info please post it.

I'm not interested in downloading any pirated ps1 games, but it seems like with this information and a little bit of fiddling it should be possible to rip my own PS1 games to .iso, convert the .iso to .pbp format that the PSP would accept, and then inject that pbp into a PSN PS1 game I've already purchased. It's sort of a ghetto way to do it, but with a little scripting it might not be too painful.

Anyone want to try this and report back?

FF7 and 8 and 9 fail to unpack with that tool. In a hex editor the PSP.pbp is similar to the PS3.Pbp's but different after the header. Ive not tried to ftp a psp.pbp to the ps3 yet as im sure that wont work. We need modified pbp unpackers for ps3.pbp files.

I don't think you read it correctly. edit: Or maybe I didn't. I was assuming the param.sfo of "Spyro" he was referring to was just the one in the game directory. Anyway, I encourage others to mess around with it. I'm goign to play around with it tomorrow and see if I can get it to work.

1) Purchase PSN PS1 title (Spyro for example, or in your case FF7, 8, or 9).
2) Get PSP pbp of game you want to play, let's say it's "Chrono Cross". (He suggests pirating it, I'm saying convert legit PS1 copy to .iso then to .pbp).
3) Extract the PSP .pbp of the game you want to play (Chrono Cross).
4) Replace the PSP game's (Chrono Cross) param.sfo with the param.sfo from Spyro.
5) Repackage the PSP pbp (the game you want to play, Chrono Cross) with new param.sfo from Spyro.
6) FTP this new EBOOT.PBP and copy over Spyro's EBOOT.PBP (back it up first obviously).
7) Restart PS3
8) Boot "Spyro" but be amazed when ${GameYouWantedToPlay} boots instead.

You can extract the iso + make pbp files using PSX2PSP

Someone already tried that but it didn't work , maybe you can do it

For those that don't have any PSX games from PS Store you can download "Xi [Trial Version]" for free from Hong Kong and Japanese stores. If you don't already have PSN accounts for these regions then set one up for Hong Kong as that store is available in English, Japanese store is only in Japanese.

If this works then it would be fairly easy to implement in a backup manager. Convert all EBOOT.PBPs to have same PARAM.SFO as base game for example "Xi [Trial Version]". Backup manager will then copy selected EBOOT.PBP (along with document.dat, ICON0 etc) to "Xi [Trial Version]" and call lv1_panic to reboot lv2, then simply launch "Xi [Trial Version]" to play new EBOOT.PBP.

Tried above method. Failed with error code. Took it about 20 seconds to fail. Gonna play with some strings and try a different game, prolly SOTN.
