Sonic Adventure 2 rips

[Shadowth117]

I'm fairly certain now that the "Shared Gun Textures" are just the textures for the aircraft carrier boss fight between Eggman and Tails, but to avoid more confusion I'll just leave them as they are unless anyone really wants the name changed again. The reason is that I found another texture set just like those, but for the Sonic vs Shadow in Green Forest boss fight. It was pretty obvious what it was this time since there were far too few textures there for anything other than that fight. I'll make sure to label this and any future boss arenas correctly.
