I would like to see a "changelist" of what Ristar went though compared to the Japanese and the others...
EDIT - Got it :
* Planet names change between the different versions of Ristar.
* The Western version's enemies were altered to appear more threatening, and the "angry" Ristar sprite is used throughout the entire game.
* Most of the idle animations have been removed in Western versions.
* A skiing sequence was added to the start of round five. Sprites for a skiing Ristar actually exist in the Japanese ROM, though it is completely unused.
* Itamor was changed from a giant mechanical cat to an ice monster. This is because of a pun ('cat-tongue') that works in Japanese.
* Anti-gravity shoes were added to round six. However, the "swimming on air" sequence still exists in the Japanese version. The same shoe sprites exist in the Japanese ROM as well.
* Notes appear next to the giant mechanical birds when they are about to peck down on Planet Neuos / Sonata. This was removed in Western versions, though the birds still stop moving their heads right before they peck.
* The names of the treasures in the bonus stages were removed. On a related note, if all the treasures are collected, Ristar says "Miracle" in the Japanese version and "Good job" in the Western versions.
* The European version of Ristar is one of the few Mega Drive games to take advantage of the larger resolution used by PAL systems.

The things "too obscene for U.S audiences" are the differences this player points out
