Redump Forum

I've found a game possessed by me that isn't on the database: Homeworld EU (English).
Using the guide on the wiki, I have successfully dumped a file and checked its MD5 hash.
The offset value is listed as mandatory, but the guide didn't go through that with data only discs. Knowing the disc creation date would also come in handy. I'll report a full dump if I receive instructions on how to do the rest of the mandatory info.

To dump discs without audio tracks is easy. just dump the disc with IsoBuster then use clrmamepro dir2dat function to get the hashes (md5, crc and sha1). You should check the image for corruption is Cdmage (in discs protected with SecuRom the disc will extract fine with isobuster but it should have 1 corrupted sector in cdmage).
Installing the game is a good idea to check for games languages and game version (sometimes the game version is in a corner of the title screen).
About the offset value it's only mandatory in discs with audio tracks.
