Pokémon Stadium (Japan)

Pocket Monsters Stadium
Developer: Nintendo EAD Publisher: Nintendo Platform: Nintendo 64 Released in JP: August 1, 1998 This game has unused code. This game has hidden developer credits. This game has hidden development-related text. This game has unused modes / minigames. This game has debugging material. This game has a prerelease article

The original Japanese version of Pokémon Stadium includes just 42 of the then-151 Pokémon, with the rest to be released as an expansion disk for the Nintendo 64DD. When the 64DD's release was pushed back again, Nintendo instead released a sequel with all 151 Pokémon, which is what was released as Pokémon Stadium in the rest of the world.

As a result, this original entry is little more than a curiosity, along with being yet another N64 title affected by the 64DD's constant delays.

Team Battles

Please elaborate. Having more detail is always a good thing.

There is some leftover code for a Team Battle select menu, a feature that would end up being implemented in the sequel.
