- New Work, Recycled Graphics: Re:coded lifts many characters models and some level geography from Kingdom Hearts: 358/2 Days, the previous Kingdom Hearts game made for the DS.
- No Export for You: The original cell phone version never left Japan due to being too intensive for most phones of the time.
- The Other Darrin: In 2.5's English dub of the remastered cinematics, Jim Meskimen voices the Genie, taking over from Dan Castellaneta, who previously voiced him in the series.
- Remade for the Export: The Japanese cell phone game was remade for the Nintendo DS for the sole purpose of bringing it to America.
- What Could Have Been: Re:coded was initially supposed to be a straight port job instead of a remake. An episodic WiiWare release a la Final Fantasy IV: The After Years was also considered.
