Hello,

I'm trying to document the regional difference between the North American and European release of the GameBoy Color game "Donald Duck Goin' Quacker (USA)/Quack Attack (Europe)" since, at first sight, theses two ROMs have no difference, because they offer the same languages available (En, FR, De, Es, It).

Using radare2 difference tool (radiff2), I have created a .csv file to compare the different bytes at a specific offset.

sha256sums of the ROMs I used were the following :

0ee26b1a12c91560ab852510a792b13d7391c2fcebf4c0c0a1d8323194eb473a  Donald Duck - Goin' Quackers (USA) (En,Fr,De,Es,It).gbc

The .csv file is available here : https://pastebin.com/raw/GvNHg8bv
