GDEMU как добавить образ MDF/MDS

$
0
0
Всем доброго времени суток, у меня делемка)) Приобрёл GDEMU, и давай добавлять образы на флэшку, CDI прекрассно работают, на консольке запускаются, НО, MDF/MDS образы не удаётся добавить полноценно чтобы Дрим их видела и запускала, т.е., образ как бы на флэшке, и в программе GDEMU_SD отображается, но в меню на консоли игры не появляются. И что ещё при добавлении образов вылетают неприятные сообщения. Пробовал конвертировать в CDI, но производитель заявлял что MDF/MDS тоже поддерживается, что я не так делаю?)
Так же подробности сообщения ниже:
************** Оперативная отладка (JIT) **************
Для подключения оперативной (JIT) отладки файл .config данного
приложения или компьютера (machine.config) должен иметь
значение jitDebugging, установленное в секции system.windows.forms.
Приложение также должно быть скомпилировано с включенной
отладкой.

Например:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

При включенной отладке JIT любое необрабатываемое исключение
пересылается отладчику JIT, зарегистрированному на данном компьютере,
вместо того чтобы обрабатываться данным диалоговым окном.

Excuse my lack of knowledge a new time.

Here the issue I have with resident evil code veronica X for the french version :
[Изображение: bug_%C3%A9cran_titre-png.5715]

I can open the pvr text file only playing with the color format, and I can't edit it because like the FONT, I can open it only with a viewer. And the alpha layer is missing...
How can I copy the french text to the original complete (X in europe) version ?
the palette are not the same either...

Thanks for you help.

finding an IDE hdd with LBA48 support

I've gotten a 40GB 2.5" IDE drive to boot dreamshell and certain games just fine. Only problem is that it only works in LBA28 meaning the bootloader bios won't boot it without pressing start and iso loaders version 0.6.6 and 0.7.0 don't want to work.

Is there a guaranteed way to find a drive that will work in LBA48? the drive is from 2006 according to the date code so its not a matter of age. Should I just look for a bigger drive like 120+GB?

Не нашел подобного, есть какой то варик запихнуть в дрим другой бп не родной? я так понимаю там на контактах 3 вида напряжения, 3.3в, 5в, и 12в, у меня вопрос сколько ватт родной блок у дрима?
если взять допустим блок питания просто левый на проводе, на котором есть те же напряжения и захимичить всё так что что бп новый просто к дримовским разъемам подрубить... будет работать или не?

я еще к чему, просто хочу один из дримов сделать хдд мод, соотвественно хард запитать от внешнего бп или от ПКшного бп, там все эти напряжения есть вроде, что если просто помимо храда с этого же БП цепануть дрим... вот какая идея еще)

Freezing at bootloader with StarTech adapter

I'm attempting to use the StarTech IDESAT2 SATA adapter (the red PCB) and a 120GB hard disk with Dreamshell. I'm finding that the bootloader will recognise the disk properly will also show up as a selectable option in the boot menu however in both cases it will immediately freeze the console whenever it attempts to boot.

I have tried with pin 1 connected, floating and grounded via a 10k resistor as has been recommended before but nothing seems to work.

CSO support

Does Dreamshell support CSO images , aka compressed ISO images ?
If yes, how ? what are the limitations ?
I can't seem to get it working on my system.

cso support

$
0
0
I've been looking for *.cso (compressed iso) support on DreamShell.
This capability is mentioned here and there, in a few places, and more importantly, there are traces of this support in many places throughout the code base.

However, every time I tried to load a .cso file, it resulted in a crash.

I was lucky enough to receive a hint from @ChristinaDreamcustDC, stating that .cso support might have been dropped in recent versions of DreamShell.
There is, indeed, one short line on the topic in the middle of RC4 release note, firmware section :

> Removed support for CSO in IDE loader to save memory =(

So that's interesting for a few reasons :

1) I'm not using IDE, but a SD Card reader on serial port. From the spelling, one could believe that it should not be impacted by the change on IDE, since after all, within `DS/firmware/isoldr`, there are distinct `ide.bin` and `sd.bin` files.

Well, the Serial Port config is clearly impacted. To confirm, I downloaded RC3, and attempted again to load the *.cso file. This time it worked.

So something broke support of *.cso files for all storage types in RC4.

2) "to save memory"

OK, this one is even more interesting. I've been looking at the code in `modules/isofs` pretty closely, and, provided that the *.cso file is using LZO compression, there is nothing that makes it consume more memory than a direct read on *.iso file. LZO decompression only costs a handful of stack variables, nothing significant.

Note that this is fairly different from zlib compression, where there is a state, which costs memory. I want to underline that I'm targeting LZO-compressed *.cso file as my primary application, precisely because it costs less memory and cpu at decompression time.

3) The code is still there.

As mentioned, I've been looking pretty closely at the code in `isofs`, and a little bit at `isoldr` and `firmware/sd`.
It's pretty clear that the ciso code is still here.
More than that, it's still active, it's not gated, and it ends in the produced binary file, meaning it consumes space, and exposes all expected symbols.

Yet, I've not found where exactly the *.cso support is disabled, if it is.

Presuming I would like to re-enable this support, is there a place to look at ?
Can this support be enabled with a simple build flag at compilation time ?

I'm interested in this topic, and may even provide some patches to improve performance of this code path. That is, if there is a way to test the code changes ....

Hi, I put this FAQ together for DS. This is a project I've been following for a while and I wanted to contribute to it.

If anybody would like to contribute to this FAQ please reply. It isn't finished and I know it could be better. I know a few
things on here may be a little outdated or could be explained better. Thanks

Also, please ignore any formatting issues, I copied/pasted from a text file. This will be fixed later.

This is a FAQ I made for Dreamshell. It pertains mostly to the HDD mod
but contains other information as well. Over the years I've copied &
pasted alot of stuff into a text for reference. I thought organizing it
might bring about something helpful for DS Users.

Thanks For All The Hard Work

Download the Following Files From Here: http://www.dc-swat.ru/page/dreamshell/

DreamShell 4.0 RC 4 CDI Image
DreamShell 4.0 RC 4 + Boot Loader
ISO Make pack v2.4

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
2 # HARDWARE MOD - http://www.dc-swat.ru/blog/hardware/874.html
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
* Adding the IDE connector/cable/board to your DC.
There are many different ways these days to achieve this.
Go do your research and find what works best for you. Many people make boards for this now
and you can also check Alliexpress for some cheaper pre-maid stuff.

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
3 # BIOS MOD
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
* The Dreamcast Bios mod is optional, but preferred if you don't want to boot from disk.
* There are four ways you can go about this.

1) You can load from "DreamShell 4.0 RC 4 CDI Image.7z". This does
not require a bios mod, but will be taxing on your gdrom drive.

2) Load Dreamshell from the HDD (With GDROM & NO BIOS Mod)
* Extract "DreamShell 4.0 RC 4 + Boot Loader.7z"
* Place DS folder and DS_core.bin in the root of your HDD (DreamShell_boot_loader_v2.3.bin file is not needed)
* Burn DreamShell_boot_loader.cdi to a CD-R

3&4) Load Dreamshell from the HDD (BIOS WITH GDROM & BIOS WITHOUT GDROM)
* Extract "DreamShell 4.0 RC 4 + Boot Loader.7z"
* Place DS folder and DS_core.bin in the root of your HDD (DreamShell_boot_loader_v2.3.bin file is not needed)
* Burn DreamShell_boot_loader.cdi to a CD-R
* Lauch DS and go to your "Bios Flasher" utility
* You will see the following in /bios/ds
1) boot_loader_devkit.bios -
Bios for loading DreamShell from HDD or SD, IGR works, start animation from a DevBox
  2) boot_loader_retail.bios -
Bios for loading DreamShell from HDD or SD, IGR works, start animation standard
3) boot_loader_devkit_nogdrom.bios -
Bios for loading DreamShell from HDD or SD, IGR works, start animation from a DevBox, check of gdrom is switched off
4) boot_loader_retail_nogdrom.bios -
Bios for loading DreamShell from HDD or SD, IGR works, start animation standard, check of gdrom is switched off
* If you are keeping your gdrom drive (or gdrom board) you can pick one of the first two bios files above depending on you choice of startup animation.
Once burned, you should be done with the process. Move to the next step if you are removing your gdrom drive completely.
* If you want to remove your gdrom drive board you have two options:
  1) install an active crystal 33.8688 MHz manually to pin B23. 
Schematic http://www.dc-swat.ru/blog/hardware/874.html
Topic http://www.dc-swat.ru/forum/thread-2257.html
2) Solder test points P096 to P154. This solution may create a bit of audio lag (I have not tried it)
and a slight delay at boot.
* Remember. "nogdrom Bios" disabled syscalls for GDROM sybsystem
"nogdrom Bios" is only needed if you remove your gdrom drive completely. If you remove
your gdrom without using this bios, your DC will hang at boot.
* Old but worth a read - http://www.dc-swat.ru/forum/thread-2250.html

4 # HDD Info
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
------------------------------------------------------
4.1 # HDD Prep
------------------------------------------------------
* I believe 2TB is the maximum but I have also heard any size HDD will work
* Make Sure Your Drive Supports LBA48 (Any drive @ 160GB or larger should be LBA48)
* Set Drive To Slave
* Create An msdos Partition Table
* Create A Single Primary Partition (I've heard up too 4 partitions is possible, I'll need to test this)
* Format FAT32 & choose the maximum cluster size (64kb)
* Keep Your Drive De-fragmented. I Defrag Whenever I add/remove files.
* Download DreamShell 4.0 RC 4 + Boot Loader & ISO Make pack v2.4
* Copy "DS" Folder and "DS_core.bin" From "DreamShell 4.0 RC 4 + Boot Loader" To The Root Of Your Drive
* Burn the CDI Image To CDR At Low Speed. Tyo Yuden Disks Work Best
* Always Turn HDD On Before Starting Console (If Powering Your Drive Externally)

--------------------------------------------------------
4.2 # IDE to xxx Converters
--------------------------------------------------------
* IDE 2 Compact Flash & IDE 2 SATA work fine, but are said to have minor
issues here and there.
* If you use an "IDEtoxxx" converter, make sure your converter has the option to
be set to slave or it wont work.
* There are alot of converters out there and some work better than other. The only brand I know works well
are the "red" Startech.com converters. There are more out there that work fine but I have not tried them.
* If you are having trouble with your converter working, you can:
connect Pin 1(reset) via 10k resistor to VCC.
* IDE to SD has many problems at the moment. I would suggest going this route.

* Something from dc-swat.ru that I copied a few years ago. Keep in mind that it is translated from Russian.
“CF does not have any problems, speed enough. But HDD works a little better in some cases,
though the games were designed for disk cache, and it does not matter in the drive or if he HDD,
are there alone. In general, they are not designed for flash memory have been, but it is just a
handful of games, so it is not necessary to dwell on it too much.”
--------------------------------------------------------
4.3 # SSDs (I need to do more research)
--------------------------------------------------------
* SSD's via Sata
* when reading a large chunk there is practically no difference, and when reading many small files the
speed increase will be noticeable
* Samsung and Crucial said to work best. sandisk u100 works.

-----------------------------------------------------
4.4 # POWERING YOUR DRIVE
-----------------------------------------------------
* It is not recommended powering your drive from your DC. Unless, you remove your gd-rom
drive completely and are going to power a 2.5" HDD or Compact Flash Card in place of your gd-rom drive.


=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
5 # Optimizing Your GD-ROMS
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
* Dreamshell Works best with Optimized GDI Images.
* Both optimized GDI and ISO images are recommended so you can enjoy a true async DMA, it requires clean sector data (2048)
* Currently there are 4 formats that DS supports, ISO, GDI, CDI and CSO(compressed ISO)(CSO appears to have been dropped)
* CDI and non-optimized GDI images will work but are not suggested because CDI and non-optimized
GDI images are slower and do not support pseudo-async for SD and true async for the IDE.

----------------------------------------------------------------------------
There are Two ways to optimize your GDI Images.
* Both these tools will optimizes GDI images, converts BIN tracks to ISO. Useful not only for DreamShell, but also for GDEMU
* The amount of files that make up a GDI will vary, but generaly you will be left with one .gdi file, some .iso files,
and sometimes an IP.bin file. Optimizing GDI’s will also save you a lot of space too, around 300mb, give or take.

----------------------------------------------------------------------------
5.1 GDI Batch Optimizer (gdiopt batch)(optimize multiple images at one time)
----------------------------------------------------------------------------
1) Download here: http://www.dc-swat.ru/forum/thread-2981.html
2) Put images in the gdi folder
3) Run optimize.bat
4) Wait for the process to end

-----------------------------------------------------------------------------
5.2 Optimize GDI Images with ISO make pack
------------------------------------------------------------------------------
* Unzip ISO Make pack v2.4
* Extract the file and move the folder sys and the file optimize_gdi.bat to a
separate folder. You will use this folder to optimize your GDI’s.
* Take all the contents of the GDI and place them in that folder.
* Launch the optimize_gdi.bat file
* Delete the sys folder, the optimize_gdi.bat file, and feel free to delete the .raw files.

6 Game Settings (may need an update)
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
* Launch ISO-Loader
* Find you game and click on it ONCE
* Click the wrench icon in the upper right hand corner
* Generally you will only need to change three settings:
* Using DMA Can Help With Lag

1) Enable/Disable Use DMA transfer (GDI / IDE Only) - turn this off only if your game does not start with this
activated. (in 90% of cases, this solves the problem of launching the game)

2) Emulate CDDA audio - try to enable it only if the game has these same tracks. Usually in the folder with the game
they look like track05.raw further in order. Many games have wired music inside themselves
and did not use CDDA (music with ordinary CD tracks) to store it.

3) Loader Memory - The vast majority of games run with a default value. But if you have already unchecked Use
DMA transfer (GDI / IDE Only), but the game still only shows a black screen, then it makes sense to try looking
for other values. First try 8cfe0000 or 8cfe8000, if it doesn’t take off, try the rest.

* Once satisfied with a configuration you can check "[ ] Save as Preset". This will
save that setting for the game, not universally.
* Remember the diskette icon will save all changes to your settings.
* Check Compatibility Lists in Section 7 for per game pre-sets in ISO Loader

* http://www.dc-swat.ru/forum/thread-3096.html
* http://www.dc-swat.ru/forum/thread-2248.html
One way is to save the game at the end of the first disk and load it from the second, it works with RE Code Veronica.
Or, if the game specifically requires changing one disc to another and nothing else, I’m afraid you
will have to play from the disc as usual.

9 In Game Reset (IGR)
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
* To reboot your Dreamcast, during a game press A + B + X + Y + START.
* This doesn't work in homebrew games.

10 # Dreamshell Applications
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Description of graphics programs in Dreamshell 4.0.0.RC4:
BIOS Flasher - BIOS firmware utility, relevant for those who made BIOS mods. Inside, everything is
intuitive - the program allows you to read, write BIOS consoles. There is also a function that allows
you to compare the image of the flashed BIOS with the image of the file on the hard disk.

File Manager - Allows you to browse the contents of connected drives, delete, rename,
compress, copy files between drives.

GD-Ripper - An application that allows you to remove the ISO image of a game from a disc inserted
into an optical drive and copy it too a hard drive or SD card.

ISO Loader - The main application responsible for setting up an image and launching it.

Region Changer - Utility for changing the region of the console and outputting the video signal format,
relevant for those who made Region Changer-mod and BIOS-mod.

Settings - Dreamshell settings, allows you to set and automatically load applications (for example, ISO Loader)
at boot. Also contains screen settings and more.

Speed Test - Application for reading/writing the speed tests of your devices, such as your hard disk or SD card.

VMU Manager - Memory card manager with an intuitive interface. This app allows you to add, remove,
backup etc… the save files from you VMU.

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
* Here is a list of these games:
http://segaretro.org/Windows_CE
http://www.dcemu.co.uk/vbulletin/threads...games-List

* Currently Windows CE/MMU games works only for IDE and GD (SD is not supported yet).
Also you need use true async DMA and ISO or optimized GDI images. There are some bugs and lags in video.
Support is good.

bootROM v1.032 Retail & DevKit Changelog:

* In BIOS menu to update the following bootROM settings (Boot animation color, SEGA license screen skip,
MIL-CD/backup direct-boot, Dreamcast main menu scenery perspective and color)

* Skip the "set date/time" screen

* BIOS video mode forced to 60hz

* Auto region patching for GD-ROMs

* Internal changes for future updates

14 # Programs For Burning CDI Images
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
* I prefer ImageBurn with the optional CDI pack.
ImageBurn runs fine in WINE (If you happen to be on Linux)
* Alcohol 120%
* Disk Juggler

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
15 # SD mod
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
The main disadvantage of this method is the low data transfer rate. This port supports speeds of up to 600 kb/s, which means
that with this connection you will have long downloads and it will also be difficult to use CDDA tracks (you will need to
convert them to use ADPCM format).

* The adapter itself can be easily purchased at aliexpress or Ebay. You can also mod the DC internally with an SD card slot.

* Memory cards have a maximum memory capacity:
SD 1.0 - from 8 MB to 2 GB
SD 1.1 - up to 4 GB
SDHC - up to 32 GB
SDXC - up to 2 TB

* Dreamshell supports SD / SDHC cards of at least class 6 (or better 10) up to 32 GB. It is possible to use microSD and miniSD
via adapters, the main thing is that the contact is good in them, otherwise they can press the card poorly.

* SD cards up to 2GB formatted in FAT16 will load faster

* If your SD card is 4GB or less, then it makes sense to format it too FAT16 :
The speed test application inside Dreamshell on the same 1 gb card shows some
advantages of using FAT16 over FAT32 on smaller SDs

17 # Create ISO From CDI - NEEDS WORK
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
* Unpack the archive "ISO_Make_pack_x.7z".

* Mount the mdf/cdi image through Deamon Tools Lite and copy all the files from the mounted image
to the "data" folder, which is located inside the folder of our unpacked archive "iso_make".

* After which we click on the batch file "hack_lba.bat", then on "create_iso.bat" and wait for the
process to complete, the newly created "isoldr_game.iso" will appear, it can be renamed as you like,
for example, "Veronica.iso". (name up to 255 characters, without spaces)

5. We transfer our Veronica.iso to the ROOT (I strongly recommend it to the root) to the SD card and
run in the same way as according to the instructions under the spoiler above.

* Launching Games with Dreamshell forces VGA Mode, bypassing the warning you would normally
receive when launching from disk.
* NOTE: Keep in mind that some games simply wont
run correctly in VGA Mode. Bangai-O is an example of this

19 # Recognizing CDDA Tracks - NEEDS WORK
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
gdi dump of the Skies of Arcadia [U]
[GDI] game, and from here after unpacking the archive we see a somewhat unusual file structure:

Code:
Skies of Arcadia v1.002 (2000)(Sega)(NTSC)(US)(Disc 1 of 2)[!].gdi
track01.bin
track02.raw
track03.bin

Alternative example where there are gdda tracks
this is for example gta 2

Code:
Grand Theft Auto 2 v1.002 (2000)(Rockstar)(NTSC)(US)[!].gdi
track01.bin
track02.raw
track03.bin
track04.raw
track05.bin

* more than three tracks, this means that the game has gdda tracks

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Note: if you put a poster of size 256x256 in JPEG format with the same name as the image
in the apps/iso_loader/covers directory (for example, for Veronica.iso the poster should be called Veronica.jpg)
it will be displayed in the application when you select a game image.

Project Overview

I've been spending a lot of time working on the official documentation lately, I've been converting .doc files, .htm pages, and images into .pdfs and .docx files with proper bookmarks.

I wrote a program called tikatree that goes through a directory and parses metadata from all the files, it also creates a directory tree, file lists, and checksums.

I used tikatree on all the documentation and SDKs I have and used the file lists it creates to make a spreadsheet of almost every single official Sega Dreamcast related file I have.

The spreadsheet lists a little over 38,000 files but I excluded most of the SDK installation files to avoid having even more duplicates. There are a couple of sheets that are already pre-filtered to checkout, one that just lists docs, another shows all the duplicate files, and one shows all of the unique files. I don't have anything that isn't already out there, this is meant to be an easier way to check things out and a quick way to see revisions.

Links:
tikatree - GitHub - Pypi
Docs on website bookstack.kairohm.dev (currently outdated)
Docs and SDKs on Google Drive
Alternative:
Excel Spreadsheet on Mega

The processed folder under SDKish means that they've been run through tikatree and they include the files that get installed.

Создание CDI образа с LBA 45000 из GDI образа игры Sega Dreamcast.

$

Файлы оригинальных дисков Sega Dreamcast изначально заточены под адрес 45000 менять привязку LBA мы не будем.

ИНСТРУКЦИЯ

1.Открываем GDI образ через программу GDROM Explorer

2.Извлекаем ресурсы в отдельную папку <data> а также IP.BIN который нужно поместить рядом с папкой <data>. Применяем хаки не изменяя LBA в файлах.В некоторых играх достаточно хакнуть только IP.BIN.

3.Создадим образ ISO с LBA 45000

mkisofs -V GAME_TITLE -C 0,45000 -G IP.BIN -l -o image.iso ./data

4.Создадим CDI с LBA 11702 из полученного image.iso (утилита cdi4dc.exe может только с 11702!!!)

cdi4dc.exe image.iso image.cdi

5.Самый важный фикс для изменения LBA 11702 на 45000.

Открываем image.cdi в Hex редакторе и спускаемся в конец файла.Ищем глазами там группу байтов 'B6 2D 00 00' в двух местах -это адреса 11702 и изменяем их вручную на 'C8 AF 00 00' это адрес 45000.
[Изображение: E2_a41VgeX4.jpg]

Размер CDI образа получился такой же как при LBA 11702 но остался привязан к 45000.Можно также создать MDF/MDS образ через mds4dc.exe а image.mds открыть в HEX редакторе и изменить адрес с 11702 на 45000.
