1. Dump with "UMD DAX Dumper Beta 0.2 by Dark_AleX":
- PSP must have fw 1.5 or any OE
- download umddaxdumper02.zip (http://exophase.com/files/psp/umddaxdumper02.zip).
- extract folder "PSP" to already connected to computer memory stick.
- launch PSP dumper and select "ISO" at Format option
- start dump and upon finish move image from root folder ms0:/ISO to computer

2. Extract info:
- use Hash calc to obtain various hashes:md5,sha1,crc32,emul. (http://www.slavasoft.com/hashcalc/)
- download SFOInfo (http://ajax16384.narod.ru/SFOInfo.rar) (this tool needs .net 2.0)
- mount PSP image as ordinary disk emulation drive and run "SFOInfo s r:\ d:\myinfo.txt" (r: emulation disk letter)
- post myinfo.txt, image hashes and in-game languages as PSP dump info

Можно дампить как на флешку, так и на комп через USB или Wi-Fi.

P.S. Где взять инфу по формату SFO файлов?

Ничего такого прежде не слышал! Я сдампил по USB и образ в точности совпадал с его данными.
И я таки нашел формат описания SFO файлов. Так что вот: SFO Files!

Ничего подобного, пользоваться USB-копированием нельзя! У меня получился совершенно другой размер образа, кроме того он даже не маунтится Daemon Tools. А вообще нужно проверять размер по смещению 0x8050 (там написана LBA диска, т.е. количество секторов на нем). Так что используйте Memstick (конечно это не очень удобно, но зато проверно и работает правильно).

English: Do not use USB method in DaxDumper! You will get bad dump, with incorrect size.

Может у тебя были локальные проблемы? Например у тебя кривой драйвер usb.prx? Возможно в нете расплодилось хакнутые и "исправленные" версии оного. Могу тебе скинуть мой комплект - с которым у меня все нормально сдампилось. Причем Дарк_Алекс писал в ридми что только wi-fi способ еще не очень стабилен, а про usb не упоминалось. А вообще стоит делать ДВА дампа. Один на MemoryStick а  второй через usb-host.

З.Ы. Возможно в скором времени сделаю свой SFO info extractor. Так как имеющаяся утилита имеет ряд недочетов и собирает не всю информацию с диска. Как сделаю - зарелизю сюды.

2Grey Fox: USBSSS и UMD DAX usb-host дампят криво у нескольких человек и под разными прошивками. Именно из-за такой неоднозначности получаемых данных у разных людей можно говорить об отказе от usb в пользу хорошо зарекомендовавшего себя memory stick дампа. (usbsss лично у меня давал неверный размер для psp demo образа в то время как  memory stick дамп через тулу алекса выдал правильный размер)

Напиши какие недочеты имеет SFO info extractor. По моему с задачей извлечения метаданных из .sfo файлов она прекрасно справляется, а дополнительную информацию по самому образу нужно извлекать совсем другими утилитами.

Тогда ясно. Ну значит только на Мемори Стик smile

Она не извлекает те же данные из BPB файла. Который так же может находится в образе. BPB - это контейнер внутри которого помимо других есть и SFO файл. Так же для типа файла MS (MemoryStick Save) она не может извлечь данные.

Попробовал 3.52 M33-3. Туда добавили нечто похожее на USBSSS (возможно просто взяли у booster алгоритм).
Для UCJB-98302 полностью неверно он сгенерил образ. Мало того что размер Iso меньше чем у UMD DAX dumper, так еще в 16ом секторе количество секторов неверный указан относительно реального размера Iso.
Отписал о проблеме HM33(одному из авторов m33) на pspx.ru, но шансов на рассмотрение ими проблемы мало.

А дамп на мемори стик правильный выходит всегда? Думаю это кривые драйвера. Но раз есть такая трабла - то стоит отказаться от усб-метода совсем.

Насколько я понял, с соответствующего треда на No-Intro, PSP Filer делает более точные дампы.
И кстати не работает на слиме sad

Поделись ссылкой на него.

А на слиме не идет видимо из-за отсутсвия ядра 1.50, для которого писалась программа. Ибо на всех Fat пспхах на кастом прошивке присутствует ядро 1.50.

с No-Intro:

Somehow, the last 2K-6KB is not extractable on the file system.
And, it sometimes causes problems to some games. (iso doesn't work. icon is corrupt. etc)
Until the dumper, you needed to dump the last file by iRShell or PSPFiler, and replace the last 2K-6KB to the FL iso.(BAHAMUT, pSyPSP and WRG did it.)
PSPfiler 3.9 automaticly repairs the last 2K-6KB to extract the last file like iRShell.

    This image has been resized. Click this bar to view the full image. The original image is sized 800x576.

This is "Puzzle Quest (J)", and posted by other forum.

From Japanese readme of PSP Filer (sorry, machine translation):
Quote:
1. At first I perform ripping from file system as much as possible.
2. I inspect size described all over the ISO and prepare for size for the difference as supplement data if bigger than the size done ripping of.
3. If I search file structure in the ISO, and there is a file written in at the point for a difference, I write in it at the right position of the whole supplement data which prepared the contents of the file with 2.
4. I add made supplement data to the end of an image done ripping of in this way.

Hi, is the guide still the best way to dump PSP games, I was reading over at No-Intro and their discussion says DA dumper produces bad dumps so I wanted to ask does redump still want DA dumps or is there a better method.

I was also wondering about the best way to dump.  I have tried two different methods: DAX Dumper and PSP Filer 4.5.  This is found in the readme for PSP Filer:
<UMD ripping tips>
Though the reason is not clear now, the last 1-3 record of UMD cannot be read from filesystem. So, doing ripping operation, the iso file is 2k-6k (1record = 2kbytes) smaller than it should be. Since version 3.9, Filer try to fill those "lost tail records" by following sequence:

1. Filer rips as large as possible.
2. Filer checks expected size by peeking ISO file, and if it is larger than ripped size, create a differential size data which is filled with 0.
3. Filer searches ISO file structure, and if there are files which uses "lost tail records", copy those data into right place of the differential data.
4. Filer appends the differential data to the ripped ISO file.

It seems to work fine now. Give me reports if the feature does not work well - to fix it.

I then checked the ISOs (using UMD Gen's sector viewer) from both programs and discovered that PSP Filer did have a few extra sectors of data at the end of the file that were not zeroed out (DAX Dumper zeroed out the last few sectors).  I am a novice at this business but figured I'd let you guys know.  A few games might not matter (Lumines Puzzle Fusion is identical both ways), but for some it does (GTA Vice city stories).  Maybe someone can also verify this and make sure I'm not just making stuff up smile.

And I see someone else was referring to this above and I'm sorry if I am repeating something (can't read Russian).

<EDIT TO REMOVE REDUNDANCY> Thank you for the info!  To be more specific GTA: Vice city stories [ULUS-10160] has sectors 828125-828127 zeroed out (this is viewing smallpad.dat, I don't know where to find the 828128th sector) when using DAX Dumper.  Using Filer, all the sectors are filled with data (and the 828127th is about 1/4 full of data).  Hmmm, so it is a waiting game for a new dumper?

BAH!  And on a disappointing side note, UMDGen does not "losslessly" (if i can say that) compress ISO to CSO.  If you compress, then uncompress the file, it yields different results... could just be a change in some part of the ISO header or something I have no idea about.  Don't know if it matters, but I find it annoying wink.  Anyone know of a program to compress and decompress without altering the original dump?

UPDATE!  One problem solved... not the most important one tho.  One can use ISO Compressor by Winnydows.  I have tried one image and it is the same when you compress then uncompress it.

Already redumped.

I've read some posts on 2ch, and found a method to find bad dumps without redumping.
In most case, DAX dumps are good. this will save us from huge redumping.

1. Open ISO with UMDGen, and check the layout of ISO.
2. Extract the last file in the ISO.
3. Check the last file in hex editor. If the last part of the last file is strangely zeroed, it's possible to be a bad dump.

The problem is that DAX dumper can't dump the last 2k or 6k, and some UMD has significant data there.
So, all you need to check is the last file.

And, it's confirmed by many people, hand-fixed isos (dump the last file with irshell or pspfiler, and fix missing data by hands) match pspfiler dumps.

So... I know some people don't like pspfiler because of [s]its slow dumping speed, no compatibility with older CFW and FW1.5[/s] or no support dumping via wifi/usb.
For such a people, DAX dumper is useful.
You can even use USBSSS, you just need to add 00s, as i wrote in No-intro.
You can fix the last files of the dax dump by hand.
It's not difficult, you just add the missing data in hex editor. (Need to be careful with the iso size)


Example of a bad dump in database, SMALLPAD.DAT of Grand Theft Auto - Vice City Stories (U) [ULUS-10160].

Now here's a question, I'm using a psp slim to do my dumps, getting 100% matching checksums when using Filer 5.5 for kernel 3.

One of the oddball discs I came across, Stealth (which has a custom demo of wipeout pure with a special set of tracks and ship) gave me annoying results...

Everything ripped fine from the game data... except for the fact that apparently filer skips the entire video subdir of the umd altogether.... repeated the process on a combination of fat and slim with the same result. Now, before I started dumping using the methods outlined here, I have used DAX dumper and the usb iso mode of modern cfw's to get the images (of course less accurate), and these methods dumped everything, including the video. Which is the preferred method as everyone seems to agree that filer is more accurate, although slower, and does this outline a larger issue with umd dumping altogether?

UMD video with updater and/or games are undumpable by any dumper except "Demo Disc for PSP Vol.1". CFW dumper can dump only the movie part and other dumpers can dump only the game part... We need a new dumper for this kind of umds...

I also have "Stealth feat wipeout pure", btw. tongue

Just a suggestion but I think it might be time to update the PSP Dumping guide and remove Daxdumper as the definitive tool to use to dump PSP games and add PSPFiler 5.9. It's been proven that Daxdumper produces bad dumps and through my experiences dumping PSP games with Daxdumper it underdumps and also has trouble dumping data in the last sector of the last file. PSPFiler however does not have these problems and always produces a good dump. Here is a link to PSPFiler 5.9 for those few PSP redumpers out there smile
