After scouring the wiki, Google, illicit ISO-hosting websites and the like, I figure I just have to ask the forum for more info on this. I have 3 copies of Sonic Adventure for Dreamcast. One of them doesn't work because I played it too much, so we won't worry about that one. The other two I have look identical to each other when you're just looking at the discs; no "Not For Resale" or "Limited Edition" or anything. But they have one difference between them that I can't understand: the title screen. On the older copy, it is just a static Sonic Adventure logo and the "Press Start Button" text. On the newer copy, the title screen has the logo and the background has an animated "ripple" effect. Beyond this, I can't find a single difference in the gameplay. No apparent bug fixes, differences in object placement...nothing. Even my save files are compatible with both versions. (These are both legitimate, retail, not-burned copies.) The only info that I have found that might relate to this comes from some cheat websites. If you Google "Sonic Adventure 1.1," you'll find that there are separate GameShark codes available for 1.0 and 1.1 versions of the game. I was pretty surprised to find that these revisions aren't documented on the Sonic Adventure page in the wiki. I have no idea if my copies of the game are the 1.0 and 1.1 referred to by these sites (lost my DC GameShark a long time ago, so can't test the codes). Do any of you have any info on why I have two different title screens, or what sets 1.0 apart from 1.1?
