Donkey Kong Land III
|Donkey Kong Land III|
Also known as: Donkey Kong GB: Dinky Kong & Dixie Kong (JP)
This game has unused playable characters.
This game has a prototype article
Donkey Kong Land III is the final game in the Donkey Kong Land series. This game is based upon Donkey Kong Country 3, just as the preceding Land games were based on their Country equivalents.
The game was first released in English for the Super Game Boy, then released in Japan for the Game Boy Color with upgraded graphics. There is no official GBC version in International versions, although fans have made a translation patch.
Everything mentioned here is assumed to apply to both the Game Boy (International) and Game Boy Color (Japanese) versions of the game, unless stated otherwise.
Check to see if the Super Game Boy border is present or unused in the Japanese version.

Rattly the Rattlesnake (from Donkey Kong Country 2 and Donkey Kong Land 2) is partially playable in this game by hacking, though he is glitched. He is playable by using GameShark code 010600DF. If both Kongs are present, a Rattly icon, left over from Donkey Kong Land 2, will appear on the bottom right of the screen just like any other animal friend would. When first entering the level, the code doesn't completely refresh the sprite (until a bonus stage is entered or exited), which means that Dixie or Kiddy will still be playable instead of Rattly. However, some of Rattly's functionality is still here, such as:
- Being able to safely jump on enemies that the Kongs can't jump on, such as Buzzes or Bristles
- Bouncing higher than the Kongs do when jumping on enemies
- Being unable to climb or swim
When entering a bonus stage with this GameShark code, the sprite refreshes to Rattly, who is glitched. Rattly doesn't actually appear as there are no such sprites here; instead, he is replaced by an immobile purple puff ball sprite that is used for other things in the game, such as explosions or when the Kongs get hit by enemies. The only way out is to wait until the bonus stage runs of time, then press Start + Select to exit the level.
It is likely that Rattly is only present as leftover code from Donkey Kong Land 2, since both games run off the same engine. It is unlikely that Rareware ever intended for Rattly to be playable in this game, since Rattly isn't playable in Donkey Kong Country 3 either (and likely isn't even programmed in the game).
In the prototype International ROM, the Kongs will not turn into an immobile puff ball; instead, the game will lock up, and the only way to fix it is to turn the game off.
Document ROM offsets for these graphics.
Much like in Donkey Kong Land 2, several unused sprites exist in this game, most of which were leftover from DKL2. These sprites can be viewed by using any of the following GameShark codes:
- 01xx0FC1 (Current sprite #1)
- 01xx2FC1 (Current sprite #2)
- 01xx4FC1 (Current sprite #3)
- 01xx6FC1 (Current sprite #4)
- 01xx8FC1 (Current sprite #5)
- 01xxAFC1 (Current sprite #6)
- 01xxCFC1 (Current sprite #7)
- 01xxEFC1 (Current sprite #8)
- 01xx0BDF (Player sprite)
The xx should be replaced with the unused sprite's ID. Note that by using these codes, the animation cycle will be based on the sprite that is being replaced.
Sprite ID: 73
Sprite ID: 30
Sprite ID: 3E
A sprite for a TNT Barrel. This sprite is leftover from Donkey Kong Land 2, where it was used. Donkey Kong Land III is Rareware's only Donkey Kong game which never uses this barrel.
Sprite ID: 70
Several barrels were leftover from Donkey Kong Land 2, but are unused in this game. The X and Check Barrels were used in Target Terror in Donkey Kong Land 2 and Donkey Kong Country 2, but have no use in this game. The Minus Barrel was, curiously, unused in Donkey Kong Land 2; its only use was in Donkey Kong Country 2, in Haunted Hall. The Light Barrel was used in Glimmer's Galleon in Donkey Kong Land 2. The Invincibility Barrel was used in several levels in Donkey Kong Country 2, Donkey Kong Land 2, and even Donkey Kong Country 3, but strangely went unused in this game. Finally, the Krockhead Barrel was used in Krockhead Klamber in Donkey Kong Country 2, as well as in Krockhead Klamber and Fiery Furnace in Donkey Kong Land 2, but has no use in this game.
Rambi Charging Animation
Sprite ID: 87
A sprite for Rambi's charging animation. This was naturally used in Donkey Kong Land 2, but went unused in this game, as Rambi doesn't appear at all. None of Rambi's other animations are known to be present.
Sprite ID: 83
A sprite for Screech. This sprite is leftover from Donkey Kong Land 2, where he appeared in Screech's Sprint. Screech naturally doesn't appear in this game, so his sprites went unused here. Oddly, he is colored purple in the GBC version, despite being colored closer to red in Donkey Kong Country 2.
Diddy Carrying Sprite
Sprite ID: 5A
A sprite of Diddy carrying an object, such as a barrel. Again, this was used in Donkey Kong Land 2, but is unused here, seeing as Diddy doesn't appear in DKL3. This is the only known sprite of Diddy in the entire game.
Early Kremkoin Sprite
Sprite ID: 39
An odd sprite, this appears to be an early design for a Kremkoin in Donkey Kong Land 2, where it was unused even in that game. For reasons unknown, it was given a blue palette in the GBC version.
Sprite ID: 7C
An odd flame sprite; its purpose is unknown. It first showed up in Donkey Kong Land 2, where it was unused from the beginning and was never removed in this game. Unlike some of the other sprites, this sprite was given an appropriate red palette in the GBC version.
Leftover Background Tiles from DKL2
DKL3 has some leftover graphics from DKL2, which consists of animated tiles for certain stages, including the ship hold, ice, lava, ship deck, dungeon, and roller coaster stages. The leftover tiles start at 7C30C in all versions of DKL3. These tiles have no use in DKL3, and are thus unused.
Unused Barrel Cannon Behaviors
Explain how to enable these features. Also, look into more unused behaviors, if there are any.
Barrel Cannons have a few behaviors that were used in previous Donkey Kong games, but go unused in Donkey Kong Land III.
- Auto-rotation (upon entering a Barrel Cannon)
- Moving up and down vertically
- Moving left and right horizontally
Among the unused tracks is Rocket Run, essentially an 8-bit version of Rocket Rush stage music of Donkey Kong Country 3. It is not known what this music would have been used for, however, since Donkey Kong Land 3 has no equivalent of Rocket Rush.
Though no known GameShark code exists to change the music, it is possible to hear it by hacking one of the bytes in the level headers – for example, changing offset 40118 (4011A in the Japanese version) from 0B to 14 will change Red Wharf's music to Rocket Run. More information can be found here (International version) or here (Japanese version), as well as here (International versions).
Leftover Tracks from DKL2
Find a less confusing way to explain this.
There are also five leftover tracks from Donkey Kong Land 2: Token Tango, Boss Bossanova (unused the first time!), Klubba's Reveille, Donkey Kong Rescued, and Titular Tableau. Unlike Rocket Run, these five do not contain pointers, so pointers must be hacked in.
These songs still exist due to the way that DKL2 handled the memory all the music. In DKL2, most of the songs resided in ROM bank 1 (offsets 4000-7FFF), but not all songs could fit into this bank due to the amount of space that they took up. Due to the way that the Game Boy's memory works, when these songs were copied into RAM, they would end up at 4000-7FFF in RAM.
The other five songs: Token Tango, Boss Bossanova, Klubba's Reveille, Donkey Kong Rescued, and Titular Tableau, needed to be placed in another part of DKL2's ROM -- 7F54E-7FFCD in the International version; 7F54F-7FFCE in the Japanese version (in all versions of DKL3, the data is located at 70000-70A7F). In order to load this into RAM, a function is called at 3747 (in English DKL2), 3778 (in Japanese DKL2), 378A (in International DKL3), or 3619 (in Japanese DKL3) to load the songs when necessary. In both DKL2 and DKL3, the five songs exist at D000-DA7F in RAM.
The function is only called on specific screens, such as boss stages, whenever the songs needed to be used in DKL2. The reason why the function is not always called is because this same area of memory is often used for other things as well -- for example, in non-boss stages, the memory is used to store decompressed map data (which starts at C600 in RAM), and the map data is almost always large enough -- if not always -- to reach D000 in RAM and beyond.
In DKL3, while the songs in bank 1 (ROM offsets 4000-7FFF) were all replaced with new songs, the other five songs were left intact, and the code to load them still exists, and is still called on certain screens, despite it being completely unnecessary in this game.
Here is a table of RAM-based pointers that each song uses. The endianness in this table is adjusted for readability, but note that unlike most of the game, these pointers are little endian, so you have to switch the two bytes when using a hex editor.
|Song||Channel 1 pointer||Channel 2 pointer||Channel 3 pointer||Channel 4 pointer|
|Donkey Kong Rescued||D649||D741||D7CE||D82B|
In the music pointer table of DKL3, some songs have "blank" pointers; that is, they point to data that results in silence. Therefore, by going to the following addresses, the pointers above can be added back in (note that only five of these need to be edited):
|Music ID||Starting address of pointers|
After adding the pointers back in, going to ROM offset 401F9 (or 401FB in the Japanese version) and changing the value to one of the values in the table above will change Barbos Bastion's music to one of the leftover songs from DKL2.
The song tempos still need to be fixed, though. The tempos can be found starting at address 4D71 and adding the appropriate music ID (e.g. for song 01, its tempo is found at 4D72). Here is a list of the correct tempos that each song uses:
- Token Tango: 70
- Boss Bossanova: E0
- Klubba's Reveille: E0
- Donkey Kong Rescued: A5
- Titular Tableau: B0
Keep in mind that when hearing these songs, after going to one level, the game will add 14 to the music index value until the game is turned off, so these songs can only be heard if you go to the level with the hacked music when you first turn the game on.
This patch (which should be applied to the Japanese version) restores all the leftover songs from DKL2, and assigns a different one to each of the boss levels (except K. Rool's Last Stand, since there are six boss levels but only five leftover songs). It also disables the functionality to add 14 to the music ID number, so you don't have to keep turning the game off to hear each song.
Unused Sound Effects
By going to ROM offset 2172 in the International version (alternately, 216C in the prototype English version, or 215F in the Japanese version) and changing its value, the sound effect that is heard from collecting all the stars in any Collect the Stars bonus stage is changed. Depending on the value changed, various unused sound effects can be heard:
- 02: The Kong Token sound effect from Donkey Kong Land. This was also unused in Donkey Kong Land 2.
- 05: The tire sound effect from Donkey Kong Land, as well as certain barrels in Donkey Kong Land 2, such as the ones in Krockhead Klamber.
- 08: The KONG letter sound effect from Donkey Kong Land, as well as the banana bunch sound effect from Donkey Kong Land 2 and Donkey Kong Country (Game Boy Color).
There are a few unused strings related to Bear. These strings exist in both the International and Japanese versions of the game.
KEEPING A TIGHT GRIP ON THE WALLET HUH? NO PROBLEM.
さいふのひもが かたいやつだな べつにかまわないけどさ
Addresses: B45D (International), 7DC5F (Japanese)
This text string takes place right after the string where Bear asks the Kongs if they want to play the card game, so this text presumably would have appeared if the Kongs said no to his question. In the final game, Bear doesn't say this and instead skips to the next question (where he offers the Kongs hints on certain levels).
GREAT! HOP IN AND WAVE YOUR HAIRY ATOMS GOODBYE!
Addresses: B915 (International), 7E103 (Japanese)
This appears right after the string where Bear asks the Kongs if they want to teleport to another world. Presumably, he would have said this if they said yes. In the final game, he says nothing before the Kongs use the teleport.
SORRY KONGS. IT'S STOPPED WORKING. TRY AGAIN LATER.
ごめん、コングたち こいつうごかなくなっちゃった あとでトライして
Addresses: B94C (International), 7E13D (Japanese)
This appears just after the unused string above. Presumably, Bear would have said this if the Kongs tried to use the teleport before defeating the first boss (since teleporting would be useless). In the final game, Bear doesn't even offer the teleport before defeating the first boss.
Unused Save Data
Unused Level Bit
Each level contains flags to determine whether a level is cleared, secrets have been found, etc., which is stored in A01C-A03F in RAM for File 1, A06C-A08F for File 2, and A0BC-A0DF for File 3. The most significant bit stores whether Dixie or Kiddy completed a level for the first time (0=Kiddy; 1=Dixie), similar to some other Donkey Kong games. However, in this game, this information is never used, and is likely a leftover from DKL2 where Diddy's and Dixie's icons would show up on the map, depending on who beat the level first.
In a similar manner to Donkey Kong Country 3, this game saves the player's current Bear Coins whenever the game is saved. However, unlike in Donkey Kong Country 3, this data is not actually used in Donkey Kong Land III. Upon loading a save file, the Bear Coin count is read from SRAM address A009 (File 1), A059 (File 2), or A0A9 (File 3), and then stored to HRAM address FFB3 (international versions) or FFB2 (Japanese version)... however, when entering the world map screen, this byte (FFB2 or FFB3) is set to 0, which causes the player to lose all their Bear Coins each time a save file is loaded.
This unused feature first appeared in Donkey Kong Land 2, and remains unused in this game, due to both games sharing similar game engines.
To prevent the Bear Coin count from being reset to 0, go to ROM offset 16A25 (Japanese version), 16404 (international retail versions), or 163DC (international prototype version), and change the two bytes to 00 00. This will prevent the value 00 from being written to FFB2 or FFB3 (depending on the version), and will allow the player to keep their Bear Coins across play sessions.
Inaccessible Blast Barrel
The downward-pointing Blast Barrel above the invisible Bonus Barrel in the wall is used to reach the barrel pointing up and to the left. Since Bonus Barrels do not appear in Time Attack mode, the Blast Barrel was added below it -- if the Kongs attempt to access this bonus in Time Attack mode, this barrel is used to prevent the Kongs from falling to their death by launching them up and left, back to the floor above and into the exit. However, the Blast Barrel to the left of the one pointing up-left is not accessible at all. It appears as though the diagonal Blast Barrel was originally going to launch left instead of up-left, but this may have been changed at the last minute. It is also worth noting that these bottom two Blast Barrels in the wall did not exist in the prototype ROM.
To access this invisible Blast Barrel, use a hex editor and go to ROM offsets 40454-40455 (or 40456-40457 in the Japanese version). Change this to BF 08. Now, when starting Whiplash Dash, the Kongs will be placed just above this otherwise inaccessible Blast Barrel -- just move a little to see it.
Sheepy Shop Card Game Record
Prior to displaying the file select screen, the game calculates the percentage of each file, based on the progress made. At one point, the game reads the record for the card game in Sheepy Shop, and checks if it is 31 (the default on a new save file) or lower. However, the game does not actually do anything with this information, since the program jumps to the same location regardless of the player's card game record. The code for this is located at F8A0 in the Japanese version, and FA15 in the international versions.
ROM3:78A0 2A ldi a,(hl) ;hl = C615 for file 1, C665 for file 2, C6B5 for file 3. ;These addresses contain the card game records for each file, ; and this instruction reads that data. ; Records are set to 31 seconds at the start of a file. ROM3:78A1 FE 31 cp a,31 ;Does current record = 31 seconds? (Note: This game often uses ; binary-coded decimals for storing values.) ROM3:78A3 20 00 jr nz,78A5 ;If not equal, branch to 78A5. If equal, go to the next ; instruction, 78A5. ROM3:78A5 0E 06 ld c,06 ;Program counter always ends up here! So reading the record ; and comparing to 31 was unnecessary.
It is possible that the developers once considered making it mandatory for the player to get 30 seconds or better in the card game. In the final game, the only thing that happens when beating the record for a given file is that Bear congratulates the player, gives the Kongs 5 extra Bear Coins, and tells them how to play the card game on the title screen.
When the game was released in Japan, the game was remade for the Game Boy Color and as a result uses full color. However, this wasn't the only change...
The Japanese title is ドンキーコングGB ディンキーコング&ディクシーコング, which translates to Donkey Kong GB: Dinky Kong & Dixie Kong (Dinky is Kiddy's Japanese name). The title screen was consequently given a slight update.
|International GB||Japanese GBC|
As the game is GBC-only, the following message is displayed if one attempts to play it on an original Game Boy. For obvious reasons, this appears nowhere in the English releases.
Donkey Kong GB: Dinky Kong & Dixie Kong This cartridge is designed for use only with Game Boy Color. Please use a Game Boy Color.
In the International version, the Bear sprite is fully animated. In the Japanese version, for reasons unknown, his animation was dropped to one frame. The tiles still exist from offsets 1F420-1F97F, but only the tiles from 1F420-1F53F are used in the Japanese version, while the rest are unused.
|International GB||Japanese GBC|
Similarly, the maps were animated in the International version with flowing water, rotating mills, smoke being emitted from factories, and blinking lights from Sheepy Shop and Wrinkly Refuge. In the Japanese version, all of these lost animation, resulting in a static world map. All that remains in the Japanese ROM are the tiles for the animated graphics (starting at 7CF24) -- the code to animate the maps was removed completely.
In the International versions of the game, the level names are centered. In the Japanese version, they are aligned to the left.
|International GB||Japanese GBC|
Jetty Jitters demo
If you wait on the title screen without pressing Start, eventually a demo of a level will appear. Jetty Jitters is the default demo, seen when Left, Up, Down, or Select aren't pressed at all, either.
In the English version, the demo works as you'd expect, and the Kongs make it to the end of the level. The Game Boy Color has double-speed mode, which the Japanese version takes advantage of, causing timing differences between the Game Boy and Game Boy Color. Due to this, the same demo desyncs at one point in the Japanese version, resulting in a glitchy demo (see right). This can be fixed by going to offset 530CF in the Japanese version, and increasing it to 0B (some other values up to 10 will also work). Alternately, disabling double-speed mode will also fix the demo (this can be done by going to ROM offset 016D and replacing the byte string with 00 00 00) -- however, this will also make the game significantly buggy and virtually unplayable.
Time Attack screen
On the Time Attack screen, your most recent time is displayed on the bottom of the screen in the International version. In the Japanese version, this is no longer the case.
Interestingly enough, tiles that read さいごのタイム (the Japanese translation of "last time") appear in VRAM from 9580 to 95EF, but are never displayed in-game. Additionally, the code to display the last time was removed completely.
|International GB||Japanese GBC|
Wrinkly and Bear dialogue
One piece of dialogue of Wrinkly and one piece of dialogue of Bear was not translated, and removed completely.
In the case of Wrinkly, she randomly says one of two pieces of dialogue when greeting the Kongs in the International version. In the Japanese version, only the first piece of dialogue was translated; the other was cut. Interestingly enough, though, there are two pointers in the Japanese ROM (at B224 and B227) pointing to the same text (at 7E2B4); both are used, and the one that is used is random.
WHY, IF IT ISN'T DONKEY - OR IS IT FUNKY? NO, DIDDY!
ドンキーじゃないかい? あれファンキーかな? いや、ディディーよ!
TEA'S READY - I'LL SAVE YOUR GAME WHILE YOU DRINK IT.
In the case of Bear, the same situation occurs when attempting to buy something without enough money. This time, however, only one pointer exists in the Japanese version (at B15E; points to 7E1C1)!
SORRY CHIMPS, YOUR CREDIT WON'T STRETCH THAT FAR.
UH-OH. LOOKS LIKE YOU'VE BLOWN YOUR BANK BALANCE.
およよ ぎんこうにあったお金 全部つかっちゃったのか
The Lost World Bug
In all International versions, a glitch exists that makes it possible to enter the Lost World without needing 35 DK Coins. In order to do this glitch, there are some prerequisites that need to be taken care of first:
- There needs to be a file that already has access to the Lost World, including the ability to enter it (i.e., K. Rool Duel has been beaten and at least 35 DK Coins have been collected).
- On the file where the player wishes to use this glitch, the Lost World must be accessible from the world map (Northern Kremisphere). This can be done by either beating K. Rool Duel, or using the level unlock cheat (on the title screen, press Up, Down, Left, Left, Down, Up, Right). However, it is not necessary to be able to enter the Lost World successfully (i.e., for this file 35 DK Coins are not necessary).
Once that is taken care of, here are the steps to perform this glitch:
- Upon turning the game on, choose the file where the Lost World is already unlocked per normal means.
- Next, enter the Lost World and either press A + B + Select + Start to reset the game, or lose all lives. In either case, wait until the title screen appears.
- Select the file where you wish to use the glitch (the level unlock cheat can be used if necessary).
- Enter the Lost World. K. Rool will not appear! To be clear, by doing this, it is possible to enter the Lost World, despite not having enough DK Coins.
This glitch works because in the International versions, when successfully entering the Lost World, a flag is set at C5BF, which causes K. Rool to stop appearing upon subsequent attempts to enter it until the game is turned off. Since the 35 DK Coin check only occurs if K. Rool appears, this means that it is possible to enter the Lost World regardless of how many DK Coins are obtained. The Japanese version fixed this by resetting this flag at C5BF upon loading a save file, which makes K. Rool always appear whenever trying to enter the Lost World. Therefore, the 35 DK Coin check will always occur as well.
A variation of this glitch also exists for K. Rool's Last Stand, but the first file needs 42 DK Coins and exactly 6 watches in order for this to work (having more than 6 watches does not trigger the glitch). This variation likewise only works in the international versions, for similar reasons.
- The Japanese version has noticeably less lag, particularly noticeable in Clifftop Critters and Redwood Rampage.
- The credits have been updated to include those responsible for the Japanese translation. (Interestingly, while most of the game was translated, the credits are still in English.)
- In the International version, when pausing the game, the screen darkens (excluding sprites, which do not change). In the Japanese version, the screen simply freezes without darkening.
- In dialogue, the text appears one kana at a time, instead of the entire text showing up at once (which is the case in the International version).
Two International versions of Donkey Kong Land III were released. The 3DS Virtual Console version is based on international v1.1.
|International v1.0||International v1.1|
The title screen changed from "Donkey Kong / Land III" to "Donkey Kong Land / III", with the Kongs and "Press Start" text moved down slightly. Interestingly, the v1.1 logo resembles that of the European box.
|International v1.0||International v1.1/Japan GBC|
In Tundra Blunda, the width of the level was extended from 215 tiles to 218 (where each tile is 32×32 pixels), with the 96 new pixels adding a pit to the right of the steel keg at the very end of the level. This was likely done to fix a minor bug where if Kiddy was facing right, touched the right boundary of the level, and threw a steel keg, it would be stuck under the snow. The Japanese version also has this alteration.
Virtual Console Changes
For players outside of Japan, who got the Game Boy version of the game, it is locked in Game Boy mode, so the Super Game Boy enhancements are inaccessible.
