I'm playing on a tated PVM also, was pretty gutted when I noticed it was using the same mode when rotated as MMP / PS & the awful Guwange port... I'm OK with having to tweak it too get it right once you're in game, but there are always going to be the overblown cropped menus when you aren't. It just feels lazy, especially when the Mushi Futari & DDP DFK were done so well... It really is strange why Cave wouldn't try to be consistent with it...
Oh well, The game looks absolutely beautiful on my (newly acquired

) 20" PVM. But it is really... really... hard. So far I can only get too stage 3.
