Kirby's Adventure vs. Nightmare in Dream Land
Kirby Nightmare in Dream Land is a remake built entirely from the ground up. It has completely different physics, mechanics, graphics, and an entirely remade soundtrack. No glitches or tech carries over from Kirby's Adventure, and Nightmare in Dream Land has its own new tech.
Other Main Differences
- Some Invisibility candies are placed by Meta Knight in Adventure. All candies are already placed in Nightmare in Dream Land
- The Rolling Turtle midboss is replaced with Phan Phan
- When swallowing an enemy with an ability, the "demonstration" does not have a hitbox. Meaning Kirby can't kill enemies with it or burn ropes while underwater for example

English vs. Japanese
There are two main differences between the English and Japanese versions that are significant for speedrunning
- Soft reseting is around 0.5s faster on the Japanese version
- The Japanese version has a bug where if you combine your discarded ability with 2 other enemies holding abilities, the mix roulette will always start 1 ability after your discarded ability. On English, your discarded ability is completely ignored.
There are no known differences between the US and EU versions of the game.
Wii U VC
Wii U VC has a few differences compared to playing on Console. There is a gray filter to help protect players eyes from the flashing affects, as well the flashing effects of midbosses and bosses being mostly removed. This means each time you kill a boss, you save time on Wii U VC. That being said Wii U VC has slower load times, and also runs at a slower framerate. This means Wii U VC is overall less than a second faster than console versions.
