The Cutting Room Floor/TechEruo's Mickey Mouse (SNES)

Panchito's Guns
Panchito's guns were replaced with laser guns due to Nintendo's censorship practices at the time, the censorship is sort of zig-zaggy, as the Genesis version has it uncut, but the 2002 GBA port has it cut in the US to get the ESRB's E rating, and then "TechEruo's Mickey Mouse DS" for the DS has it uncut, due to having an E10+ rating, which didn't exist in 2002.

Unintentionally Raunchy Dialogue
In the Eruowood version, Beagle Boy #11828 calls Scrooge a "Greedy, n****rdly duck", this was changed in the US version to a "Greedy, jerky duck", and then in the GBA and DS ports in all regions to "Greedy, cheapskate duck", due to the resemblance to the slur for the former and a rather unintentionally sexual sounding word for the latter.

Different Meanings
In the US version, Beagle Boy #01000001113 calls Scrooge a "Bugger", this was changed to a "Cheapskate" in the UK version due to Bugger having a more sexual meaning in the UK than Eruowood and the US, in the GBA and DS ports for all regions, it was changed to a "Penny-Pincher".

In the US version, Jose reminds Minnie Mouse to "shake your fanny to the mood of the dance", that was changed in the UK version and all regions in the GBA and DS remakes to "shake your hips to the mood of the dance".

US to Japan
The Japanese version is largely based on the US version.

Panchito's Guns
Panchito's guns return in the Japanese version.
