GameCube DVD dumping

[Organic]

To dump GC DVD you need mod-chipped GC and Broad-Band Adapter (BBA). Then you must use option in your shell to "backup" disk. Usually shell asks you to insert original disk and get backup from http://192.168.1.32/backup.iso

After you get backup, you can use HashCalc (www.slavasoft.com/hashcalc/index.htm) to calculate MD5, SHA1, CRC32 and eMule checksums.

GC disk ID is placed on the disk itself (not on back-side of box cover). Example disk ID is DL-DOL-GWRP-EUR.

Game version is written at offset +7 from beginning of the dump (one byte). 0x00 mean v1.00, 0x01 mean v1.01 etc.

DOL MD5 is need for better recognition of disk versions.
Dont use this: You can extract DOL by GCTool 1.2 from menu Tools -> Extract DOL..
See the next post.

Disk size is always 1.459.978.240 bytes.

Я выяснил, что GCTool неправильно извлекает DOL файлы из GCM и поэтому все DOL MD5 полученные ранее - неправильные.
Поэтому я сделал специальную утилиту для подсчета правильной DOL MD5. Также утилита извлекает GCNDefault.dol
Если у вас есть возможность, исправьте старые DOL MD5.

I found that GCTool incorrectly extract DOL files from GCM images, so all previous DOL MD5 checksums are wrong. Sorry
I wrote small console app for correct DOL MD5 calculation. Additionaly it extarcts DOL from GCM as GCNDefault.dol.
Please, use this tool when calculating DOL MD5 and fix old DOL MD5 if its possible.

Is the "Marker Code" in GCTool the same as the "GC disc ID" you are talking about in the first post?

We discussed GC Disk ID naming convention and decided to use ID inscribed on disk surface. Obviously GCTool cant telepatically guess real ID, so it may look the same, but may not.

To Dremora: сделай пожалуйста новость на главной странице, что обновлено руководство по созданию чексумм для куба.

Oh woops I meant to say "Game version".

Following data structure (called "DVD DiskID") is placed at the beginning of every GC disk :

Code: Select all

typedef struct DVDDiskID
{
    char    gameName[4];
    char    company[2];
    u8      diskNumber;
    u8      gameVersion;        // 0 mean 1.00, 1 mean 1.01 etc.
    u8      streaming;
    u8      streamingBufSize;
    u8      paddingZero[22];
} DVDDiskID;

"MakerCode" shown in GCTool is actually DVDDiskID "company" record. This is predefined game developer unique number, assigned by Nintendo license agreement. For example "01" is company code for Nintendo itself. All game makers have different codes.

Please, do not ask questions later in this topic, because someone may be confused by unneeded information.
Thanks.

I've sent you an email to with another question so as not to confuse anyone reading this. I'm just letting you know here in case it went to your spam/junk folder since we don't have a PM system.

You could also dump GameCube discs from a Wii, no modchips or extra hardware necessary, just as long as you have a wireless router.

You pretty just just need cIOS and the cIOS DVD Dumper: http://wii.waninkoko.info/ (yeah, I know that Waninkoko doesn't make the safest programs, but these ones can't do any real damage).
