In the Virtual Console release of the game, Jynx's sprite is altered to change her skin color from black to purple, keeping in line with the character's redesign since the international releases of Pokémon Gold & Silver in 2000, which was implemented following complaints from African-American writer Carole Boston Weatherford that the original design was evocative of blackface imagery.

While Game Boy and Game Boy Color sprites only allow for a maximum of three colors, the game's in-battle assets are composed of multiple 8x8 sprites composited together. Thus, the Virtual Console release was able to recolor Jynx's skin by only altering some of these tiles to replace black with purple. As no other Pokémon use this method, this makes Jynx's altered design the highest-detail Pokémon in any version of the Generation I games.
