As noted in the announcement from February, Pokémon Trading Card Game supports both local and online multiplayer. Notably, this includes the Card Pop! function that is required for players to obtain the Phantom Cards Mew and Venusaur. Multiplayer features were disabled in the Nintendo 3DS Virtual Console release of the game.
Pokémon Stadium 2 meanwhile notes "Nintendo 64 Expansion Pak Found" on its title screen, indicating that the game's base resolution is boosted from the N64's standard 320x240 to 640x480.
