Wanpaku Duck Yume Bouken
In 1990 Nintendo released Duck Tales for the NES/Nintendo Famicom. However, some changes, respectively censorships have been made for the final release. Probably the reason was the strict policy of Nintendo-USA not to have religious symbols in their games. This revised version was eventually merchandised worldwide.
In that game you play the role of Scrooge McDuck looking for treasures.
Compared were the US-prototype version and the ordinary US version.

altered cross on coffins
At the level “Transylvania” the crosses on the coffins were transformed into R.I.P. labels. Within the prototype the level is called haunted house.
Within the moon-level an enemy has been altered belatedly.
This level is called “surface of the moon” in the prototype.
There are several other alterations, but these only affect the text. Additionally, some of the levels were given different sounds/names.
