Kirby's Adventure is one of the most graphically advanced games released for the NES. Released near the end of the console's life cycle in 1993, this game features a great amount of unused content – some of which would end up in future Kirby games.

It was also remade in 2002 for the Game Boy Advance as Kirby: Nightmare in Dream Land. There was also given a 3DS port in 2011 as 3D Classics: Kirby's Adventure, using the original NES resources with minor differences like depth effects.

Not so much the objects themselves, but the way they behave.

Unused Ability

These tiles of a tiny Kirby are found in sprite bank 8C, along with the graphics for the Mike and Ball abilities. These graphics were possibly used for an ability that no longer exists in the game. The oddly-sized Kirby would have been used for a shrinking animation (Kirby does the raised hand pose for abilities like Crash and Light that aren't demonstrated right away).

This Mini ability might have been replaced with the UFO power. All of the other ability tiles are close together in graphic banks 80-99, while the UFO Kirby graphics are located in bank C6. UFO is also the last normal ability by ID, further supporting this theory.

12 years later, this ability would finally be implemented in Kirby and the Amazing Mirror...although in that game, you can't slide while using this power.

Unused Song

Track 16 (10 hexadecimal in-game) in the Sound Test is an upscale version of the Kirby's Dream Land title screen.

Unused Graphics

Bank 14

An untranslated duplicate of the invincibility icon. The icons normally used by the game are stored in banks 40-4B.

Banks 24-27

Graphics for seven different water tiles of this style. Only two appear in-game.

What they would have looked like animated.

Bank 47

This icon does appear in-game, but is nearly impossible to see normally. Using the Mix ability, it can easily be seen during the roulette selection of abilities using an emulator's frame-by-frame advance feature. It was meant to be used when Kirby hopped into a cannon and, oddly enough, is used in the French version!

This icon was also restored and used in the 3DS port 3D Classics: Kirby's Adventure.

Bank 50

This entire graphics bank is unused! It would have been used for the second dark room in the game.

How the stage could have looked.

Bank C0

The bank used for the Level intro font seems to contain graphics for an early version of the stage hub HUD. This is much darker than the HUD used in-game and the graphics are very different.

Bank D8

This bank contains data for a 7th stage door graphic. The largest level hub only has 6 stages in it, so this is never used.

Minibosses

These three frames aren't shown in-game at all. The Mr. Frosty frame is similar to frames seen in future games, where it's used after he charges at you and falls down. The Poppy Bros. Sr. graphic is similar to his normal death frame, but his feet are on the ground. The Rolling Turtle graphic is strange – perhaps he could hide in his shell during battle.

HAL Zone

At the end of the first room in Stage 2 of Vegetable Valley is the name "HAL" in the form of many Star Blocks; however, it is inaccessible due to the Warp Star beforehand that forces the camera to stop going to the right. A simple glitch will make the Warp Star disappear and allow you to see the HAL blocks. Oddly, a Broom Hatter is present on the "L". Going through the door at the end will take you to the next area.

This place is also present in Kirby: Nightmare in Dream Land, but there is no way to access it.

Revision Differences

There are two versions of Kirby's Adventure: PRG0 CHR0 and PRG1 CHR0. This section lists all the known differences between the two.

Text String

At ROM address 0x7FFF0, PRG0 contains the peculiar string RGKK_SetStillX. In PRG1, this was changed to an unreadable hex string (FF DD FE F7 FF 77 FF BF FF DF FF FF 7F FD FF F5).

Intro Story

The spacing of the "KIRBY'S ADVENTURE" text is incorrect on the first few story pages in PRG0. This was fixed in PRG1.

Collision Bug

It is possible to pass through the sloped floors in the second area of 7-3. The easiest way to do it is to jump towards the point where the upper and lower slopes meet, then quickly press Up to inhale air right before Kirby touches the point. If done correctly, Kirby will pass through the slopes. If you do this with the structures on either side of the screen (as pictured to the left), Kirby will get stuck, forcing you to reset the game if you haven't cleared the stage yet!
