Pytanie: Co otrzymasz, gdy połączysz Pokémon i Tetris Attack? Odpowiedź: Pokémon Puzzle Challenge, jedna z prób Nintendo zwiększenia atrakcyjności gry poprzez zmianę jej marki.

Panel de Pon GB#

To do: Descriptions of the menu entries are needed here

For those who don't know, Pokémon Puzzle Challenge is pretty much the same thing as Tetris Attack, which in turn is the international rebranding of the Japanese game Panel de Pon. Characters from the latter game can be found in the ROM, suggesting that this game was originally meant to be a Panel de Pon game, but got rebranded partway through. (In case you're wondering, this was a Pokémon game in Japan as well.)

That said, Panel de Pon GB does exist in a very early 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 some of the menu options.

If using a non-GBC Game Boy, Panel de Pon GB can accessed from the GBC-only screen by pressing A (24x), B (24x). (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 must first be triggered from the title screen by entering Up (2x), Right (4x), Down, Left (10x), Up (4x), Right, Down (6x), B. Once the screen is displayed, pressing A (24x), B (24x) 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.

Some of the mugshots in the middle image are even loaded into VRAM on the puzzle level select screen. All but three of them are then replaced with Professor Oak's head.

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.)

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 panel 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.

Ekran Tylko GBC#

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.

Unused Music#

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.

Virtual Console Changes#

Like all Game Boy Color games for Virtual Console, there is no hardware support or emulation for the Game Link Cable, so all multiplayer functionality is inaccessible.
