I recommend you do not get OCD over Xbox dumps there are very few verified xbox dumps yet anyway and these are all DVD9 even though some games fit a CD and only 3 or 4 games actually take up the space of the DVD9 disc aka dual layer disc, most games will fit a standard DVD5 disc, there is no advantage to having a full DVD9 image of a game that will fit a CD, xbox games like a few other systems have a lot of junk data that is not game data to fill out a full DVD9 disc so a RAW dump v.s. an iso file made up of all the game data is going to be half the size of a raw dump and not have any data missing from it
It would be better if there was a database of the files that make the games up for xbox rather than a database of raw dumps
xbox dumps are not the only ones like that wii and gamecube can be like that also, just not to the extreme of xbox games, i.e. gamecube games came on 1.4GB discs all dumps are 1.4GB when a raw dump is done due to junk data, Wii games are the same except that they came on standard DVD5 discs and only came on DVD9 discs if the game data used more space than a standard DVD5
for Wii and GC I do recommend raw images though to avoid any chance of bad scrubs ect... this has happened in the past with much better dumps done later on, but this is a learning curve for dumpers always has been hence bad dumps and rips existing on all platforms.
