Stripping an ISO from a home made psx eboot - here's how!

[mrdude]

Well guys, I decided to download a few games today just to test my theory out - plus I didn't like some of the games as they still had hotshots icons in - anyway here's info on how to strip the original iso out of the eboot.


Download winhex and open your eboot file.

The iso starts at offset - 00150000 - so strip all info out of the file before that.

Ok we don't know how big the iso is - but we do know this....

Look at the bottom of your file and then get a hex calculator (windows one in scientific mode will do) - then what you do is look at the address of the bottom row of your file and minus this hex from it - 8a20

Once you strip that you are left with the original iso file - so save whats left of your file as whatever.iso

Open your new iso with isobuster or some other iso software to confirm it's working and you should see all the psx files inside...that's all folks....

[StoneCut]

Thanks, this might come in handy.

[Ooops]

Nice find could be handfull some day, thanks for sharing it.

[dick]

mrdude can u explain it more clearly? thanks.

how u strip the info?

i tried highlight all before 00150000, took a long time of shift+page up.
i select remove from the edit menu.
said will be save as backup in temp.
after waiting. i save as .iso from winhex.
cant read with alcholhol the iso.

tried again but this time winhex say invalid txt when i tried to save as iso.

Drag and drop the .pbp onto the exe in this package, it will make file "out.iso" in the same dir as the PBP is in - I have only confirmed it working with a cloneCD image made into a PBP and back to iso (the out.iso is a few thousand bytes short of the original .img and does not have any of the extra data normally used by clonecd in the ccd and other files), the iso itself seems to be intact when checked using IsoBuster, but one cannot be too certain if it will be usable on the PSX without some extra data.

[matomato]

nice find! ;)

[NSCXP]

is there another tool that makes the eboots be converted back to ISOs?
everytime I canvert it back with the tool above & try it thought a emulator it says its invaild image.

please can somebody reply or help with this problem.

[Cobra.uK]

Quality cheers. :)

[cory149]

NSCXP: nope, no other tools as of yet, that is why I wrote PSXstrip. What emulator are you trying? Do you know for sure that it works with iso's without bad data, directly?

Check your final iso with isobuster or a similar iso tool like daemontools or something, as I said before, PSX games have extra data that refer to bad blocks as a protection strategy, which are essentially discarded when you make an iso isntead of a clonecd or alcohol image.

At any rate, there could be a problem with the data that is stripped off the end, I just used Mr.Dude's number wrather than dig about for it myself. Verify your iso (preferably with something that isn't using the PSX bios) and if it is the tool that is causing the problem I can fix that.

I have tried it with epsxe and it wont run the game i'm trying is Thrill Kill but the game runs fine as eboot, any ideas?

Are you saying if we rip our games as a clonecd, go EBOOT, then back to ISO, we should be able to run it as an ISO on our PSP or a cso if you want it compressed further?

[cory149]

then what you do is look at the address of the bottom row of your file and minus this hex from it - 8a20
NSCXP: This is the problem. mrdude's length offset is NOT standard for every file. There does not appear to be any size reference to the original iso size (at least, not that I have found at any rate), and the data that appended at the end of the iso appears to be padded between the iso and the extra data.

Are you saying if we rip our games as a clonecd, go EBOOT, then back to ISO, we should be able to run it as an ISO on our PSP or a cso if you want it compressed further?
Not at all. To run it on the PSP it has to run through the PSP's PSX emulator (which currently means popstation is the only way to do so with an iso).

[orochiPSP]

Seem's to be working perfectly for me. I've tried it with 3 games now and the new isos work in epsxe.

Many thanks!

Yep, same here, thanks! :)

[cory149]

:) Cool. Just in case though, I went back in and did a bit of looking at the disc format. Managed to grab the sector size and numbers (so no getting a different sized file from the original like I did with .img files) and added a couple verifications that check to see that the PSX data is in the header. Also greatly improved the disc io speeds, so it should take alot less time to extract.

NCSX: give this one a shot, it should tell you if it's finding a valid disk image at least. It's possible that the iso you are extracting just isnt made with a program ePSXe recognizes (and possibly my program won't recognize it either).

Was ThrillKill ever actually released? As far as I always thought, it was only leaked as a beta and never actually sold...?

[flatwhatson]

Awesome work cory149, thank the lord for someone on these boards that writes open and portable code!

Compiles fine under linux, works like a charm. Tested with FF8 disc 1, resulting iso is identical to the original.

I've been looking into the popstation EBOOT format, trying to work out what the header and trailer data that's added to the iso in DATA/UNKNOWN.PSAR is, to re-implement popstation in open, portable code. Popstation crashes harder than the zepplin under linux (still makes the EBOOT fine though).

Your code is of great assistance!

Props.

[mrdude]

Superb work m8, I just tried it with a croc 2 eboot - and extracted the exact iso file i used to make it....That was made with ultraiso.

This is one sweet tool. Thanks.

[peter_poiuyt]

hey sorry noob here, but from what i understand the psx 2 psp isos are NOT readily playable on epsxe? did they compress it or something. see i wanna play silent hill but my old disc is not working and i found a dl of a psx to psp but its only like half the size of a normal psx title.

basically what i'm gettin at is are these psx to psp dls the original psx titles or something new altogether?

oh and can i use my old psx games on the psp as is or do i have to convert them or something?

[NSCXP]

flatwhatson,

how did you manage to get FF8 working, My version is PAL, I made the ISO image them coverted it to NTSC then made it into a EBOOT, when I load the game on the PSP it shows the playstation logo and then goes black screen.

Any ideas?
Please can you reply ASAP
Cheers & Thanks in advance

[cyx]

cory149, with the new util does it still miss the header ? thus hex compare of ISO files will be different ?

[xtofu]

what a nice thing.

i'll be looking for this kind of tools for a long time since the popstation released.

some game u try on psp and really want to play it on ps2, so need this tools.

thax so much.

[StoneCut]

Thanks for the tool cory149

[markmcrobie]

Excuse my ignorance, but what's the usefulness of this?

[katsika]

nice little tutoriaa man,i ll try it out...

[p$p b0y]

Was ThrillKill ever actually released? As far as I always thought, it was only leaked as a beta and never actually sold...?

no, at the time it was thought to be "too gorey" for the public (lmao), hopefully i can get my friend to lent me his thrill kill, if he can find it (its an amazing game)

[cory149]

p$p b0y: that is what I figured, the only time I have actually played that game was years ago and a friend was (over) excited about having a CD burner plus PSX chip... how times change.

StoneCut: :) 'welcome.

cory149, with the new util does it still miss the header ? thus hex compare of ISO files will be different ?
As far as I have been able to test, it has reproduced the original files I put into popstation.exe - let me know if it missed something and I will try to reproduce it and fix it as I did not test very many images/types.
Excuse my ignorance, but what's the usefulness of this?It's meant to pull the iso/bin/img back out of popstation created pbp files. (Help save HDD space. Help people who didn't realize Dark_Alex may very well later update OE to add compression to PSX pbp files. Gives me a reason to look at Mode 1/XA disk images closer and perhaps learn something.)

peter_poiuyt: the original files that come from PS store and are downloaded to the PSP with a PS3 are compressed and possibly crypted, so no, unless you find a way to decompress/decode them there is no way they will work with ePSXe.

If there are games with Audio tracks included, will this extract the audio tracks? I know the audio tracks can be within the .bin files, but can they be within .iso?

I'm using the NTSC version I'm afriad... that works straight up.

It shouldn't make a difference, but I'm using popstation for linux and the ripped BASE.PBP.

I think your problem is the PAL iso...

Google helped me... uh... locate "psx isos" that are all ntsc ;)

[WrathofGod]

I tried your second build and got this error with my chrono cross iso.
Valid image id not found.
press enter to quit.

but with the first build I used it and it extracted the files fine... without any hesitation.:confused:


<----- Little confused here

EDIT: the game doesn't run after extracted :'(

[cory149]

The first build didnt check for anything. The current one only supports mode1/XA type disks, so if it doesnt find the image header that says "PLAYSTATION" it tells you it is an invalid image (unsupported). Try extracting with the other GUI pbp maker if possible, it probably has this stuff corrected already (I have been gone for a few days).

Yeah i found the gui pop maker thing after I tried yours and it works. Also your first build those images did work for some reason I can't get epsxe to work I had to dl PSx and it worked :/ But good work on your program :) maybe you'll continue to work on it as it does what its suppose to :D

Noob here....just a warning....

Anyways I am so confused on how to strip after minusing(?) hex (whatever from the one he gave to us.... can someone go through this process clearly please because i want to play my broken version of GTA2 on my PSX and the only thing i could find was an EBOOT of it.


PLEASE HELP!!!1

[WrathofGod]

download the program here http://forums.maxconsole.net/showthread.php?t=40946 tidus_ffx2006 and just where it asks for iso select it and there should be an option to extract it :)

[tidus_ffx2006]

thank you SO much i really appreciate it.

[WrathofGod]

thank you SO much i really appreciate it.
No problem I know how much it means as I was wanting some games for the psx I couldn't ever track down and now I have em :)

[tidus_ffx2006]

Sorry to bother you guys again but this GTA 2 image I got was only 14MB when i extracted it...becasue there was no radio stations or movie modes...anyways...i burnt it and it worked fine but then i thought: i just wasted a 700MB disc for 14MB

So finnaly the question: Can i put multiple games on one cd then like make a menu to choose which game i wanna play after swapping?

Once again i am a noob so yeah......much appreciated

Thanks

Sorry for double posting :(


I just got a PSP and GTA :Liberty City Stories and i just happened to let my sister play it in the toilet (but it wasnt grand theft auto ) and she made it fall in the toilet

so i bought a new psp and my sister found GTA and touched the place you cant touch and scratched it and now it wont let me do any missions:(


it wont start and i was looking up how to play burnt UMDs on a memory stick
i have a 2.71 psp and i heard if you downgrade it you could "brick" the psp
i have this mother board that i heard if you try to downgrade it it wont work. it was something like Ic003. Question: does these precautions come with upgrading it to a custom firmware? or will i have my psp bricked if i try to upgrade it as well? i really want to play GTA with the missions by downloading (and im pretty sure its legal since i have the game) th ISO and putting it on a custom firmware psp


Thanks alot

I'm a little confused here. First off how long ago did you buy the 2nd psp? If at all try to return it and goto eb games or something and buy a used one. Ask them to see what firmware is on the psp. If its below 2.0 your set. but i'm not sure what the highest firmware is you can downgrade from.

[tidus_ffx2006]

sorry i geuss ill put it pretty striaght foward

i am quite broke so is there a way that will possibly safely make me be able to play gta lcs iso instead of downgrading but upgradidng to a custom firmware. btw my firmware is 2.71


please help and it is a TA-082 motherboard

thanks

tidus_ffx2006

[cory149]

3.03 is the highest firmware you can downgrade, though you definitely need the unpatched GTA:LCS disk to do it with.

All I can say, is why are you posting questions like this in a thread titled "stripping and ISO from a home made psx eboot"??? Not even close to the correct topic for your questions.

Hello, I have a PSP PBP that was made from a PSX game and I'd like to convert it back to something playable with PCSX for Mac.
I've tried PSXstrip and PBP Unpacker but when I mount the resulting image, it's an audio CD with a single noisy aiff file.
Any idea ?

Try a different program. I would try popstation gui I think it's called. If not just search popstationa and you should be able to come up with one.

[xamelosnoc]

I believe the problem comes from the disk images not the emulator, BTW PCSX is the only functional one on Mac OS X.

[WrathofGod]

cant you emulate windows or windows programs on the mac i thought?

[xamelosnoc]

I can but it won't help in the present case.

[quiquezero]

dunnoe what's happening! but how long does this take!?
i dragged the file inside, is there anything else i have to do to make it work?
it just says the direction it is in, and stays there.
i tried the file brave fencer musashi...
file name is EBOOT.pbp any problem? =/
