The game is designed for a 4:3 display, with 16:9 support being limited to the title screen, menus, and credits. Because of this, the original North American and European releases feature colorful custom borders which occupy the unused screen space during 4:3 segments when playing on a 16:9 display. However, this attracted complaints from players, as the static nature of the borders risked causing screen burn-in after prolonged periods of play. Consequently, later revisions remove the borders, instead using standard black bars.

Mario Party 8 was recalled in the United Kingdom due to the character "Kamek" saying the word "Spastic". The word is considered highly offensive in the UK, as it has been used to mock the disabled.
