1: I haven't actually checked... I didn't realise the japanese version had that. When I get a chance I'll have a look see and snap you guys a photo
2: I've been playing this on my 32inch Samsung and I have no real gripes with the graphics at all. Nothing looks jaggy persay, it actually looks good and is visually quite nice for a Wii game. What I will say is that when in conversations, the screen in split in half for each character just like Hotel Dusk on the DS. It's nothing major it just makes me feel like I'm playing on a DS
Played about 5 hours of it yesterday, looking forward to spending some more time with it too.
