Unused Music

A short 8-bit loop that may have been used for testing, otherwise its intended use is unknown.

Debug Features

Cacti speak Japanese.
...But what does it mean?
This game has text or audio that needs to be translated. If you are fluent with this language, please read our translation guidelines and then submit a translation!
Notes: Debug menus need to be translated.

Debug Room

HRR - Debug Room Map.png

There is a debug room, that looks like the Clubhouse, which can be accessed with the room selection cheat code with the ID 0001 (see Unused Rooms).

About this room:

  • You always start between the "1" and the "2".
  • The music played is the Clubhouse Theme.
  • Unlike the Clubhouse, you can't interact with any object except the blackboard and the TV. Note that the TV only shows a black screen in the debug room.
  • The top-left exit doesn't work and you just go out of the map.
  • The main exit leads to the world map, but before that it asks which story flags you want to set on, from 0, none, to 7, all of them.

HRR - Debug Room Story Flag.png

HRR - Debug Room Story Flag Choice.png

  • Jingle is a Ham-Ham formation tester. You can see the 100 formations used during the cutscenes.

HRR - Debug Room Formation Tester.png

  • Interacting with the "0" in the Japanese version will play the "sticker get" animation and give you one sticker at random.
  • Interacting with the "0" in the European version will make all sprites disappear for a short time and give you all stickers (except the 451) and sticker backgrounds.
  • Interacting with the "1" does not seem to have any effect.
  • Interacting with the "2" will bring you to the Ham-Ham Lawn before giving an ingredient to Bo. In some cases it doesn't work.

Debug Menus

Elementary, my dear Cactus.
This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: Is there a way like the Rainbow Land Debug Menu or Party Selection Menu to access the other menus?

This game still has some functional debug menus.

It is possible to trigger any of those by setting the correct value for the next event pointer at the IWRAM's address 04:5A28 (EU) or 04:59C8 (JP), for example with the cheat code 03005A28:XXXXXXXX (EU) or 030059C8:XXXXXXXX (JP). While interacting with almost any object (e.g. talking to a Ham-Ham or picking up sunflower seeds), setting this event pointer then advancing the dialogue allows you to access the event.

Rainbow Land Debug Menu

An inaccessible though active debug menu can be opened by talking to that shop hamster in Rainbow Land. One way to access it is to go in front of the "0" in the Debug Room and use the room selection cheat code with the ID 012F. In this menu you can choose:

  • To deliver an invitation to a particular hamster, with a confirmation message:

HRR - RL Debug Menu Confirmation.png

  • To deliver invitations to all the hamsters. In that case, you'll see this message:

HRR - RL Debug Menu All Set.png

  • To watch the 2nd ending.

Party Selection Menu

Elementary, my dear Cactus.
This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: What exactly do the flags do?

Some rooms hide a green elderly Ham-Ham at the origin (top-left), which normally can't be accessible.

Either traveling to the origin; forcing him to an accessible spot; or, setting the next event pointer to 081F2E87 (EU) or 081A3277 (JP).

The first menu lets you:

  • Change what Ham-Hams are in your team.
  • Test formations (much like Jingle in the debug room). When quitting out, you'll be stuck on the elderly Ham-Ham.
  • Change flags (Unknown what flags' purposes are).
  • Warp directly to Rainbow Land's elevator (next to the train station).

The options in the team-changing menu are as follows:

Page 1 Page 2
(Clear Team) Howdy
Hamtaro Dexter
Boss Maxwell
Oxnard Sandy
Bijou Stan
Pashmina Cappy
Penelope Panda
(Next Page) (Close)

Note that clearing the team won't alter the first Ham-Ham you control.

Sparkle Coast Event/Team Menu

There is a debug menu for testing the events that occur in Sparkle Coast. This lets you activate some story event flags and change your party between 4 formations that are used during the storyline of this area. There are 2 pages in this menu, but oddly no connection between them, as you can't go to the second page in the first one. The dialogue parts uses Snoozer as the speaking character.

Note that all "Yep-P" and "No-P" will be replaced according to your language set.

First Page

You can trigger the first page by setting the next event pointer to 08208932 (EU) or 081B8D12 (JP).

Second Page

You can trigger the second page by setting the next event pointer to 08208B5B (EU) or 081B8F3B (JP). Option 7 will do the same as option 7 in the first page. Option 8 has no text in the menu. For some reason, option 10 incorrectly uses the dialogue of option 9 at the end, saying that you switched to a 4 members team while you actually switched to a 3 members team.

Sparkle Coast Bijou's Warp

Another Sparkle Coast debug dialogue. This time it just lets you warp to the beginning of Sparkle Coast's chapter. Bijou is the speaking character.

Due to some error, the second text after your choice will appear without clearing the dialogue box, making it unreadable.

You can trigger this event by setting the next event pointer to 082084BE (EU) or 081B889E (JP).

Unused Rooms

All these rooms can be accessed using a cheat code:

  • When you are in the game, enable this code: 03006C90:XXXX (EU) or 03006C30:XXXX (JP), where XXXX is the room ID.
  • Open and close the menu.
  • Disable the code.

Clover Elementary Section

5 Clover Elementary maps linked to each other are not used in the final game. There isn't any interaction in these maps, but the loading zones and links to other maps are defined, and even links with used maps.

Elementary, my dear Cactus.
This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: The top-left and top-right edges of the desk trigger the climbing animation, so there may have been something that you can climb at these points that is an other exit for this room.
Hmmm...
To do:
Add the other unused rooms.

Unused Items

Cacti speak Japanese.
...But what does it mean?
This game has text or audio that needs to be translated. If you are fluent with this language, please read our translation guidelines and then submit a translation!
Notes: The image descriptions and the dialogue need to be translated.

There are 5 items never used in the final game. Each one has name, images and description in the Japanese version. In the European version, they lost their names, showing only the images and the Japanese description. All of them can be seen in the item menu with the cheat code 02001E78:000101XX, where XX is the item ID.

Additionally, there is an unused dialogue (in both versions) involving the "Ham-Ham Ring" and another item, the "Lucky Gold Card" (see Unused Events for more information).

Unused Events

This game has text or audio that needs to be translated. If you are fluent with this language, please read our translation guidelines and then submit a translation!
Notes: All dialogues from those events need to be translated.

Ham-Ham Ring Exchange Dialogue

There was an event where you would have exchanged with an Ham-Ham NPC the Lucky Gold Card for the Ham-Ham Ring. However, the Ham-Ham Ring wasn't used in the final, and this event goes unused.

Saying "Yep-P" in this dialogue gives you the Ham-Ham Ring and takes out the Lucky Gold Card of your inventory if you have it.

You can trigger this event like the other debug menus by setting the next event pointer to 081D9D70 (EU) or 0818A0B4 (JP).

Japanese Translation

Boss's Orange Dialogue Early Version

There is an event in the first chapter where you find Boss searching for the Orange on a tree and request his help. While this was used, another version of this event still is in the game, which is longer than the final one. The early version also doesn't use the orange color for the word "オレンジ".

You can trigger this event by setting the next event pointer to 08217486 (EU) or 081C7A36 (JP), but it will not always work because characters are moving during the event.

Sticker Hermit Dialogue Early Version

There is also an early version of the Sticker Hermit's explanations about stickers. While the final versions uses a star system to rank the stickers by rarity, this dialogue refers each rarity rank by "「レアど」?". You choose between 4 explanations instead of 5, one for each rarity, in the final. At the end of the dialogue it will loop on the final version.

You can trigger this event by setting the next event pointer to 081FB5EE (EU) or 081AB9F3 (JP).

Unused Backgrounds

These backgrounds are also considered as rooms, so they can be accessed using the room selection cheat code.

Rainbow Background (Room ID: 015E)

HRR - Unused Rainbow Map.png

This background is located just before other rainbow backgrounds used for the introduction scene (which are rooms 015F and 0160), so it could have been used for that introduction scene too.

Cutscene Background (Room ID: 016A)

HRR - Unused Cutscene Background.png

This background looks like other backgrounds used for end chapter cutscenes. However, there is no information or text that can be related to this background.

Regional Differences

Title Screen

Japan Europe
Hamtaro RR - Title Screen (JP).png Hamtaro RR - Title Screen (EU).png

As with past titles, both versions of the game have different title screens, each using their region's respective title and subtitle. The European version adds a literal rainbow between the two not present in the original and changes the color of the suns on the sides of the subtitle from red to yellow/orange. The European subtitle also has the colors of the rainbow in a sort of backwards order, with an extra light blue added in for most of the "w" and a repeat of red at the beginning instead of the straightforward Japanese version.

Music

Title Theme

The Japanese version of the game plays a new, longer 32-bit rendition of the Japanese Hamtaro intro, "Tottoko no Uta", while the European version uses a newer version of the international theme. Unlike previous games, the Japanese theme is nearly the same length (albeit still shorter by about 10 seconds) as the international's instead of being roughly half or less.

Japanese Title Theme European Title Theme

Character Table

Both versions of this game use the same character table. However, alphanumeric characters were redrawn for the European version (including some that were never used in the Japanese version), as well as the buttons. Most of the symbols on the extended table were slightly moved up, and some characters were added.
