Expanded party
An expanded party is a Pokémon party containing more than six Pokémon.
The player can find many glitch Pokémon and unstable hybrid Pokémon in the expanded party.
The expanded party can be accessed by having over 6 Pokémon directly (D163 in Red/Blue), or by using a glitch to access/swap them without actually having them. This can be done with both the closed menu Select glitch (Japanese versions only) or no expanded party international Select glitching.
In Pokémon Red, Green, Blue, and Yellow
An expanded party can be obtained with the SRAM glitch (including from a save file erased with Up+Select+B, which will give the player 255 party Pokémon), Super Glitch, special menu select glitches (by swapping lift destination and Cerulean City badge man entries), and arbitrary code execution.
From the expanded party, it is possible to perform many tasks; such as:
- Altering items and registered Pokémon in the Pokédex (if a Pokémon is swapped with the 10th).
- Digging up Pokémon that the player doesn't own.
- Performing the Fossil conversion glitch.
- Enabling the player to walk through walls (if the 62nd Pokémon is swapped with the 63rd).
In Pokémon Red, Green, and Pokémon Blue (Japanese), the closed menu Select glitches perform party Pokémon switches ignoring the number of Pokémon in the party; which allows for 'simulated' expanded party switches. A similar exploit (but requiring multiple glitches) in the English versions can be achieved with map size memory corruption.
Sometimes freezes occur when switching certain Pokémon beyond slot 6 or with a closed menu Select glitch due to the zero maximum HP glitch, in which one of the Pokémon has 0 maximum HP but over 0 current HP. This can be worked around by having a 0xFF Pokémon above the desired slot to place the 0 maximum HP Pokémon, so the game doesn't have to handle the HP (with the problem possibly caused by a division by zero when the game attempts to draw the HP bar).
The expanded party has been banned from 151 Pokémon speedruns for both (Red/Blue and Yellow); the rational that using the glitch to obtain Pokémon wouldn't be seen as obtaining them.
Memory addresses
Notes: This assumes no potential technicalities and that the extrapolations are correct. At least the species byte 1 and main data has yielded results, but has only been briefly been checked. This data is for Pokémon Red and Blue; addresses are -1 in Yellow version, and +5 of what they were in the English versions for non-English European versions. For Japanese version data, see Expanded party/RGBYJP.

Swapping mechanics
Since each party Pokémon has four distinct pieces of data, for party Pokémon beyond number 6, those data regions often overlap, which causes the effect of swapping two Pokémon to be non-obvious. In addition, the data regions for Pokémon main data extrapolates to the stack region as well as the Echo RAM region, which may also cause complicated behaviors. Discounting possible stack corruption issues, the procedure for swapping two different party Pokémon works as follows[1]:
- Swap their species bytes 1 using the HRAM byte
hSwapTempas the buffer. - Swap their main data using the buffer
wSwitchPartyMonTempBuffer($CC97 for R/B). - Swap their Trainer names using the buffer
wSwitchPartyMonTempBuffer. - Swap their nicknames using the buffer
wSwitchPartyMonTempBuffer.
The details of each individual swap operation should only matter in rare cases, such as when the main data regions of the two Pokémon overlap or when one of them overlaps with the buffer (both thanks to the Echo RAM). Denoting the Pokémon selected first as Pokémon A and the one selected second as Pokémon B, each individual swap operation works as follows:
- Copy the data for Pokémon B to the buffer.
- Copy the data for Pokémon A to the data for Pokémon B.
- Copy the buffer to the data for Pokémon A.
In Pokémon Gold, Silver and Crystal
An expanded party can be obtained with the ????? party overloading or arbitrary code execution. It is more prone to freezes than in Generation I.
The expanded party with specific requirements can enable the party-based map distortion glitch found by werster and RingRush.
Additionally, it is possible to cause limited memory corruption by swapping the moves of party Pokémon beyond slot 6 using the "move" option.
In Pokémon Emerald
| This article is incomplete. Please feel free to add any missing information about the subject. It is missing: {{{1}}}. |
The expanded party can be accessed indirectly with Glitzer Popping, directly through the News Reporter trick (itself currently requiring Glitzer Popping), and possibly both directly and indirectly through arbitrary code execution.
Other names
