The games working title was Legacy of Goku 2: Future Shock. The title was dropped mid-way through development. All three LoG games were meant to have subtitles.

If the game detects that it is being run illicitly, when Gohan first goes to the world map, a message will appear saying "This game will not run on the hardware found.". You will then be sent to the title screen.

The opening FMV is present in the US and Japan (international) versions but was removed in the European version due to the need for storage space to add other languages.

Though none of the Dragon Ball Z: Legacy of Goku games were released in Japan, a special version of the second instalment called Dragon Ball Z: The Legacy of Goku II: International was released exclusively in Japan. This edition was published by Banpresto and featured updated character portraits and the character's names changed to their original Japanese names, though Mr. Satan is still referred to his English name "Hercule" on a parade float.

There are six Super Nintendo game cartridges on display in the game. These include:
•Final Fantasy IV (released in the U.S. as "Final Fantasy II")
•The Legend of Zelda: A Link to The Past
•Secret of Mana
•Super Metroid
•two other games that have yet to be identified.

There is also a Game Boy Advance sitting on an adjacent table.

There is a variant of the pirate robot built by the Red Ribbon Army.
Its description states "This giant robot bears the insignia of the Red Ribbon Army. Scanning indicates that this robot was designed for military purposes. The thick Geromatium armor on this robot makes it invulnerable to most conventional attack."
The original was built by pirates. Also, the name Geromantium refers to a character from the series named Dr. Gero.
