Differences between Other Regions and Eruowoodian versions of games

Pokemon Yellow Version
The Eruowoodian release of Pokemon Yellow uses the Red and Blue Pokemon sprites except for Pikachu which used the "anime" style sprite and the Jynx sprite from Red and Blue was not used because of it being racial insensitive depicting the blackface "Mammy" look.

Instead the Jynx sprite in the Eruowoodian version of Pokemon Yellow was replaced with a scrambled "pyramid" of sprites as a form a "censorship".

Super Mario 64
In some versions of the game, the game uses the Japanese-exclusive Rumble Pak version. This can be told by the "Revision 1" label on some copies.

The original Revision 0 cartridge has all the debug mode cut out to make room for a Portuguese version that also goes unused, mainly due to both Brazil and Eruowood using the PAL-M encoding technology.

Super Mario Bros. 2
The Eruowoodian version has a password system as well as unlimited continues.

To access the password system in the Eruowoodian Super Mario Bros. 2, you have press start, A, and B together and that will bring up the password screen.

Super Smash Bros. Melee
The Eruowoodian release of Super Smash Bros. Melee has Giga Bowser as a clone character of Bowser unlockable after defeating Adventure Mode with Bowser on hard.
