Notes

Panel de Pon GB

Characters from Panel de Pon can be found in the ROM, suggesting that Pokémon Puzzle Challenge was originally meant to be a Panel de Pon entry but got re-branded partway through.

That said, Panel de Pon GB does exist in a very early and generally unpolished state, as the characters and music are all there. The game can even be accessed on a regular Game Boy or Super Game Boy. Interestingly, the game's CGB Bootstrap ROM palette is remarkably similar to Tetris Attack for Game Boy and its Japanese version, Yoshi no Panepon, except that it is more yellow than green.

Japan	US	Europe

The European version of this hidden mode renames the "FIREWORKS" option to "SCROLL".
All options save for the last two correspond to options or secrets available in the main game. Their functions are as follows:

GAME MENU	Gamemode settings.
GAME MODE	Swaps between Marathon and Garbage mode.
GAME LVL	Difficulty level. Effects differ between gamemodes.
SPEED LVL	(Marathon mode only) Affects speed of the stack's automatic rise.
GRBG LVL	(Garbage mode only) Affects size of falling garbage blocks.
START!!	Launches a game.
OPTIONS	General settings.
SEMI-SIGN	Toggles pseudo-transparency of the signs that pop up for combos/chains.
SCORE LIM	Whether the score maxes out at 5 or 6 digits.
CRY	Swaps between two sets of combo/chain sounds.
SPEED LIM	Whether speed levels above 50 keep increasing stack speed or not.
STOP	Toggles stop timer given when doing combos or chains.
SCROLL	Allows the player to raise the stack while panels are popping.
MUSIC	Toggles music playback.
SOUNDS	Toggles sound effects playback.
DANCING	Toggles panel animations.
RESET	Sets all OPTIONs to their default state.

If using a non-GBC Game Boy, Panel de Pon GB can accessed from the GBC-only screen by pressing A (×24), B (×24) (you will hear a chime after pressing each button the required amount of times). If on a Game Boy Color or a newer handheld, the GBC-only screen can be triggered from the title screen by pressing Up (×2), Right (×4), Down, Left (×10), Up (×4), Right, Down (×6), B. Once the screen is displayed, pressing A (×24), B (×24) will launch Panel de Pon GB.

Alternatively, it can be accessed by using Game Genie code 1F0-23B-80E which will start Panel de Pon in GBC mode, or 1F0-3AB-91E in any other GB mode.

Other Leftovers

To do: This game has a lot of compressed graphics; documentation and decompressor on Jul.

In addition to the above, very barebones version of Panel de Pon GB still buried inside the game, there are many leftover graphics from a more complete version which likely would've had features similar to the final Pokémon Puzzle Challenge.

• 

  Mugshots of various Panel de Pon characters.

• 

  Zoomed out mugshots, some additional English text and less Engrish. Some of the graphics were localized since they are still used in the final game.

• 

  Even more mugshots. Note that the bottom two characters, Zilba and Kain respectively, were later used in the Nintendo Puzzle Collection version, which replaced nearly the entire cast with redesigned characters. The second character in the middle row appears to be unused in both the Super Famicom and GameCube releases.

The graphics from the middle image are loaded into VRAM on all stage select screens besides Challenge mode's, but any mugshot that would appear in that mode is then replaced with the corresponding Pokémon, Gym Leader, or Professor Oak's head.

• 

  0x7D615: The Nintendo logo screen, reminiscent of the SNES version.

• 

  Assembled mockup of the Nintendo logo screen, part 1.

• 

  Part two of the Nintendo logo. It appears these were animated.

• 

  Mockup of the Nintendo logo screen (3).

• 

  0x9E3A5: The title screen.

• 

  The Title screen, as seen after applying the title screen patch.

• 

  0x9F2B4: The title screen's "Push Start" message.

• 

  0x3E5E4: Graphics for the suspend save screen.

• 

  0x3E8FE: More graphics for the suspend save screen.

• 

  Restored suspend screen.

• 

  0x135B37:Garbage blocks. The last set is reminiscent of Tetris Attack (SNES).

To restore the PDP Title Screen, use this xdelta patch and apply it to the Japanese ROM:

Besides the uncompressed mugshots, there are many blocks of compressed graphics still left over from Panel de Pon, including the title screen, which reveals that the game was supposed to be called Panel de Pon GB before the Pokémon rebranding. (All offsets are for the Japanese version.)

A restoration is in the works here.

Character Artwork

Game Genie code 160-23B-80E will boot the game in a mode that displays redrawn "character bio" artwork from Panel de Pon. Different artwork will be loaded depending on the value at RAM address CDA1 (JP) or CDC1 (US/EU).

Unused Stage Graphics

Setting the RAM address for the current stage graphics (JP:CEBF US/EU:CEA2) to values above 0D will load themes left over from Panel de Pon GB.

• 

  0E: Flower Stage

• 

  0F: Wind Stage

• 

  1B: Zilba?

• 

  1C and over: Fallback?

0F, 11, and 13 use the same borders as the Flying, Grass, and Water Pokémon themes respectively. Only the background animation differs.

1B and over load the same palette and border as 1A (with a broken "incoming garbage" area). 1C onward use the background from training mode, which lacks vertically offset animations, so the last loaded background is reverted to as the stack scrolls.

Unused Scenes

Artworks showing unused scenes from Panel de Pon GB can be seen on the map in VS. COM mode by setting RAM Address DF1F to 01. Also set CE25 to 01 to make sure the background and sprites for the current scene align with each other. CF09 is the image id, and setting CF08 to 2C or 38 sets the screen to black or white while the tiles load.

! Panel

The ! Panel exists in all forms. The inverted red version is an unused state, while the black rendition would be used for the upcoming panels which never appear.

There is a routine that verifies all panels at the start of the round. Set RAM addresses D245, D24B, D24D, D251, D257 D25D, D263 to 07. This will set the last row of panels to the ! panel.

This unknown tile appears in the game bank.

Unused PPL Title Screen

The game was going to be titled Pokémon Puzzle League at one point, matching the N64 game. Using these Game Genie codes for the Japanese version will load this screen in place of the Puzzle Challenge title screen.

27B-C5D-E6F
4AB-C4D-E63
4BB-C3D-D57
27B-C2D-E6F
4AB-C1D-E63
32B-C0D-6E2
27B-BFD-E6F
48B-BED-E6B
D2B-BDD-E6A

Debug Menu

Game Genie code 220-23B-80E will start Pokémon Puzzle Challenge in a screen setting viewer/CHR set viewer. Soft resetting from the main game after enabling the code is recommended for more stable results (especially on the European version, since many screens rely on a language being selected).

You can view all stage backdrop sets, special events, and boss introductions. Pressing Left, Right, Select, Select+Up, or Select+Down depending on the screen allows testing of various functions such as listening to Pokémon cries, scrolling the screen, setting the menu cursor, and other specific functions.

Entry	Description
0000-0003	Save, resume, congratulations, and game over screens. Left, Right, and Select move the game over screen's cursor.
0004-000B	LineClear introduction screens.
000C-002E	Character and Pokémon portraits.
002F-0048	Battle portraits. Shows all frames and their corresponding animations. Left and Right play the Pokémon's cry.
0049-007C	Garbage block sets for every Pokémon. Can be scrolled in all directions.
007D-0085	Overworld "islands" for Challenge mode.
0086	Scrolling Pokémon League hallway. Can be manually scrolled in all directions.
0087-008E	LineClear "ROUND CLEAR!!" screens.
008F-010E	Stage graphics and layouts. Some of these combinations are normally inaccessible.
010F-0116	Puzzle mode completion screens.
0117-0128	Ending screens for the various modes. Select+Up decreases credits scroll speed, Select+Down increases it.
0129-012C	Pokémon egg portraits.
012D-0146	PKMN Data screens. Select+Up/Down scroll "Face Select" cursor, Left/Right change selected Pokémon without updating the screen.
0147-0155	Boss battle introductions and defeat cuscenes. 0155 depicts an unused event, as beating Lance always triggers the ending on the spot.
0156-0157	Stop timer animations.
0158-0159	Pikachu splash screen.

GBC-Only Screen

There is a black-and-white GBC palette programmed for the GBC-only message screen, likely added for the aforementioned Easter-egg game mode Panel de Pon GB. Game Genie code 1D0-23B-80E will start the game on this screen in GBC mode.

(Source: Mezmorize, nensondubois)

This screen might have leftover code from Tetris Attack's title screen, as a connected copy of the main game or Tetris Attack will mistakenly treat being on this screen as being "multiplayer ready".

Leftover Japanese Language

Setting RAM address CF2B to 00 while on the European version's language select screen will highlight an otherwise inaccessible Japanese option, complete with its own flag sprite.

While the game does retain some Japanese text and assets, a good amount of content is still replaced with its English counterpart when playing on this setting. Interestingly however, the Japanese Link Error screen was kept, but modified to remove a mention of Panel de Pon GB.

Unused Text

To do: Unused Japanese text for Panel de Pon GB character bios and easy mode ending has been found.

Unused Music

To do: There's a LOT more unused songs than the ones listed here, mainly the entire Panel de Pon GB soundtrack. Get all the music uploaded along with providing their ROM offsets.

There are three unused music tracks in the game's data. Game Genie codes ??3-C3B-F72 ??4-88B-F72 (where "??" is the song ID number) will play your selected song at the main menu. Song ID 54 is a duplicate main menu track, while the Panel de Pon track ID values are 1E, 1F, and 20.

Unmapped Tracks

Besides the above songs, there is a lot more unused songs and jingles from when the game was going to be Panel de Pon GB. They are unmapped, so the songs need to be patched in. The music pointer table is located at 8190E in the Japanese version, and nearly every pointer after 8196E is set to play no music. The offsets for all songs here are for the Japanese version.

Unused Sounds

The sound that plays when the player does a combo or chain in Panel de Pon GB mode changes depending on the RAM address for player character (JP:C0CE US/EU:CEA3). If the "CRY" options is set to "VOICE", the game will play approximations of the voice lines from Panel de Pon. "SOUNDS" mode, meanwhile, will usually play all-new sound effects.

Value: Character	Voice	Sound
00: Lip (Default)
01: Windy
02: Sherbet
03: Thiana
04: Ruby
05: Elias
06: Flare
07: Neris
08: Seren
09: Phoenix
0A: Dragon
0B: Thanatos
0C: Cordelia

When the stack is near the top of the screen, a different sound will play to signal a longer stop timer. This sound is the same for all characters, but still has a SOUNDS and VOICE variant, unlike the main game which always plays your Pokémon's cry when "PKMN Cry" is enabled.
