Klonoa: Door to Phantomile, Famitsu has posted a perfect comparison shot between the new Wii version and the PlayStation version. These two screens put next to each other will disabuse you of the nostalgic memory of Klonoa on the PlayStation looking nice, and will completely shatter any idea of the Wii version being a simple port.
What it does suggest is that Klonoa on the Wii is a very close remake of the PlayStation game. This environment, at least, looks completely identical in layout. There may be extras attached (probably), but we expect this to be an upgraded remake rather than a remix.
