Great news man, please upload the dumps to Mega.nz, OneDrive, Google Drive ect so we can get started working on the data and try to get the dump working.. very exciting!

 

アップロードは難しいと思います。ご不明な点がございましたらお知らせください。大きすぎてアップロードできない場合は、メールで送信して、データを調査して処理することができます。インターネットの速度が十分であれば、MegaまたはGoogleドライブにアップロードします。地域社会に貢献していただきありがとうございます!

Hello
Compress the data and upload V2.06 and V4.52
I'm uploading now, but it's taking a while because of a garbage-like internet connection:
I will participate in the auction now and will upload V3.58 if I can make a successful bid
Upload to Google Drive
V4.52 is 29.7GB
V2.06 is 12.6GB
is
Contact me again when upload is complete
See you

 

PS

Can be ported from 4EX to 2, but crashes when displaying results
This time again

Let me see if I can ask around with people who have previously tried to do the dump, perhaps it's more complicated with certain arcade SSDs.

thanks

You should have asked before you started !

Does the ssd still work in the arcade cabinet ?

Some security measures will destroy a arcade machine specific hdd / sdd mbr when connected to a windows PC !!!

 

The standard is tu use CHD format.

Read it very carefully bit by bit literally !!!

You use it at your own risk !

Ask, if not sure !!!

hello , try with Macrium Reflect software. for me the best and easiest software to use

Yeah and let windows / macrium reflect handle sector level copying, even hidden sectors and partitions ?

 

There was a really sad story in year 2010, when Nirin hard drive died and the arcade technician took the disk from another machine to make a copy using Acronis in Windows.

The copy is made, everything seems to be fine, but after connecting this HDD to the machine it no longer boots and says that you have a problem with the drive.

Stubborn technician didn’t stop and took a drive from third arcade.

The same story.

Nothing can stop our person, he calls his pal in another city to send him Nirin drive by mail.

All 4 machines were sent to London (Namco Europe) paid by technician who thought that stubbornness could win it all!

Recovery cost almost €8000.

 

So you know, some hdd's / ssd's have CUSTOM firmware !

https://medium.com/@ValdikSS/researching-protection-and-recovering-namco-system-es1-arcades-1f8423fdeb3b

 

To qoute from the above article, concerning Namco  ES1 machines:

 

Fortunately no, everything is simple yet evilly genius: drive’s Master Boot Record (MBR) has it’s Disk Signature field filled with zeros.

Right as you connect this HDD to your Windows machine, the OS sees zeros and don’t like it, generates a random Disk Signature and silently writes it to the disk.

Game motherboard reads MBR in boot process, sends it to the TPM.

When it’s time to decrypt the data, PCR are not exactly the same and decryption is not possible.

This was done intentionally—every Linux disk partitoning utility generate random Disk Signature, not zeros.

 

What to do if you’re as stubborn as the man in the above story and you have no working machines anymore?

Fear not!

Just write 4 bytes of zeros where they should be in the MBR, at the offset 0x1B8.

You can do it like this in Linux:

$ sudo dd if=/dev/zero of=/dev/sdX bs=1 count=4 seek=440

 

Every kind of system got their own kind of security protection

And no, specialists will not make these tools needed public !

 

Try to clone these HDD's and make it work, good luck !

Inform us all when you succeed :very-good:

If you need help Dumping / backupping these drives, send me a message.
Because you need certain software and hardware, if there is something you don't have, then it saves me hours of typing.
Once i know what you have, i can guide you the right way.
And these drives can't be just copied, you need to do a hotswap inside of the original pc.
And there is another connector which needs to be taken loose after the boot up.
Otherwise it will reset half way the backup process and you can  start all over again.
Backup will be around 90GB, so make sure you have the space available.
When using usb3 connections, it takes about 30 minutes to make the backup.

I'm waiting for someone to upload the uncrypted data of the songs to port them directly on the Switch version actually.
Also, I made a tool to port songs from AC and Mobile to Switch in a second, here it is if someone have a modded Switch :

Looks like OP was just hoarded it for themselves lol.

 

Ringedge and Taito Type X Zero are the easiest things to dump ever, anyone can do it easily. 

 

Golden rule: never discuss anything about arcade PCB hacking or dumping to public.

 

The dump for GC 4EX have been up in nyaa for a while, have you got it working? could I ask for guidance if you have. No posts seem to exist about it which means it's either working and people are keeping it low-key or it's not working and therefore has no post about it.
