|Pokémon Crystal Version|
This game has a notes page
Pokémon Crystal is the update to Pokémon Gold and Silver with a focus on Suicune and the mobile phone stuff, which is removed from all versions except for the Japanese version. Pokémon Crystal was notable for being the first Pokémon game where you could play as a female character.
Other than the Mobile Adapter features requiring the GBC, what makes Crystal a GBC-only game if most of the code is reused from Gold and Silver (but more so from Gold as per the unused stuff)?
Confirm this. And Crystal also made minor changes to many maps as well as some big changes (e.g.: Ice Path, Champion room at the Pokémon League) so the Gold and Silver maps could still be there as well.
All of the unused maps from Gold and Silver remain in the ROM of Crystal. The Game Genie code to restore the Safari Zone gate's door is even the same!
Like the non-Japanese versions of Gold and Silver, the international releases of Crystal contain a hidden debugging function to reset the clock. However, the process to activate the menu was made more complex:
- Hold Down + Select + B
- Release Down + B, leaving Select still pressed
- Hold Left + Up
- Let go of Select
Alternatively, the GameShark code 010464CF can be used.
Introduction And Title Screen Music
Dump the music.
The music from the opening sequences of Gold and Silver remains in the ROM, despite not being used in Crystal.
Super Game Boy Features
Even though Pokémon Crystal is not compatible with the original Game Boy models or the Super Game Boy, it has an unused Super Game Boy border programmed into the game. It can be enabled by setting the flag at offset 146) to 03. It is a leftover from the Japanese Gold version in all releases; being that the border does not fit well with Crystal, it was likely that it was never intended to be used at all. To enable the Super Game Boy features on real hardware or on an emulator, use the Game Genie code 031-46F-E6A (note that because the Super Game Boy checks for the bit after booting, you must first power it up with any game that has Super Game Boy enhancements inserted into the Game Genie, then insert the Pokémon Crystal cartridge with the Game Genie to see the hidden features).
It is worth noting that music was planned to play on the error message screen that appears as load functions are present.
There are several other unused palettes that may be leftovers from Gold and Silver. Game Genie codes ??9-A8B-91B + ?69-A7B-B31 will load any of these unused palettes. ATTR_BLK settings are not actual palettes but rather attribute settings and they appear black, so they won't be documented.
The unused commands are listed at 0x9A86.

In Gold, the default name for the player's rival when a blank name is provided is SILVER in English and シルバー in Japanese. This remains true in Crystal, which further suggests that it was developed from Gold rather than Silver.
In contrast, the default name in Silver is GOLD in English and ゴールド in Japanese.
For the sake of consistency, every Pokémon in every Pokémon game is given a Shiny variant, including Mew. However, all Mew distributed to Generation I games have a fixed set of DVs that prevents them from becoming Shiny when traded to Generation II games, leaving its Shiny form unobtainable without cheating or glitches (the Trainer-Fly glitch, for example, would produce a Mew with random DVs). Shiny Mew would later be used in the Generation III games, available through both the Faraway Island event (where the player could capture Mew normally, giving it a chance to be shiny) and the Mystery Mew distribution (the first person in line would receive a Shiny Mew).
The sprite changes in the localizations of Gold and Silver also apply to the localizations of Crystal. Except for Jynx, the changes in the Pokémon sprites were also taken into account for the Japanese Crystal.
The other changes in the layouts and graphics of the games were also reused for Crystal.
One of the primary differences between Japanese Crystal and Gold & Silver is that the Pokémon Center in Goldenrod City is replaced with the Pokémon Communication Center (or PokéCom Center for short) to allow access to the Pokémon Mobile System GB. Japanese players could connect their Game Boy Color or Game Boy Advance to their mobile phones using a special link cable and access the wireless network, which was shut down in December 2002. This feature is very similar to the Global Terminal featured in HeartGold and SoulSilver.
This is what the PCC looks like from the outside. Its sign says "For mobile tips! POKéCOM CENTER"
This is what the ground floor of the PCC looks like. The left-most desk continues to operate as a Pokémon healing service, while the center desk acts as the mobile trade center, and the area to the far right is the Pokémon News Machine where players could read about each other's Pokémon adventures. The stairs go to the typical second floor Pokémon Center layout with the regular link cable rooms. The pink door in the upper left corner leads to the Administration Office.
And this is the Administration Office, which can be accessed from the aforementioned door at the top-left of the map.
In the international releases, there's an unused warp right above the stairs on the ground floor of the regular Pokémon Center that leads here. Without hacking the ROM or using glitches, it can be accessed with GameShark code 0160E4D4, which alters the behavior of the warp tile so that it behaves like a hole tile.
GS Ball Event
Was the U.S. distribution method similar to one in the JP version? I can't seem to find any specifics about this.
Players in the U.S. also had the ability to get Celebi through the New York Pokémon Center, but only during its opening month (November/December 2001). Although no legitimate method was used outside of Japan and a portion of the U.S., the code remains in them.
The GS Ball event got reprogrammed and adapted to the regular Pokémon Center in the localizations. This event can be activated by setting the byte at 0x3E44 in a regular English v1.0 save file to 0x0B or by using GameShark code 010B44BE.
The Japanese version's Mobile Center feature was disabled internationally, causing some graphics to become unused. Its translation is incomplete as various text remains untranslated and displayed as gibberish since most of the Japanese characters are no longer present.
The Mobile Center (shown as "Mobile" in-game) can be accessed on a save file with GameShark code 010576CF in all non-Japanese versions.
The English localization made the most progress, followed by German and Spanish. The profile entry screen defaults completely blank except in English.
In the Japanese version, this feature can be used to send data of timed mobile battles to the Japanese Pokémon Stadium 2 via the Transfer Pak, which is then converted into a battle video. The Vs. Recorder item in recent Pokémon games provides similar functionality.
Like the Mobile Center, the Mobile Stadium feature was disabled internationally, and it suffers from the same incomplete translation issues. It can be accessed with the aforementioned GameShark code 010576CF in all non-Japanese versions.
In the English versions, its entry on the menu is misspelled as "Mobile Studium".
Occasionally, a connection attempt will display a Pichu animation with music. This screen has intact Japanese text.
Replace Italian picture with English.
Curiously German and Spanish, like English, translated the intro text, while it was left blank in Italian and French. In addition English revision 1.1 and the European languages have a glitched background due to an unintentional LF→CRLF/CR→CRLF conversion.
Check how it actually works in the Japanese version.
Another major difference in the localizations of Crystal is the Battle Tower. Unlike in the Japanese release, it does not rely on the Pokémon Mobile System GB so it's open to everyone. This also means that access to the tower in the Japanese version after the shutdown of the mobile service is impossible; however, the GameShark code 0160D7D4, which alters the behavior of the warp tile so that it behaves like a hole tile, can be used to enter it (the "walk through walls" GameShark code is required: 01003ED1 01003FD1 010040D1 010041D1).
Dump sparse41.miniusf here.
Copies of the game released outside of Japan feature three unused music tracks, which originally played when accessing the mobile phone functions.
Game Genie code ??A-F2A-B3B will play any song at the title screen menu. They can also be listened to with the GameShark code 01xxA9C2, which modifies the overworld music.
This remix of the Pokémon Center music is used in the Pokémon Communication Center, once the player successfully connects to the Pokémon Mobile System GB service for the first time. Its ID is 66.
A remixed version also appears in the Japanese version of Pokémon Stadium 2 as "sparse41.miniusf" when accessing the equivalent "Mobile Stadium" menu.
Has ID 5E. It is used in the Japanese version on the mobile connection screen.
