Description

Pokémon World Stadium is a post-game–style ROM hack designed as a universal DLC for any completed Pokémon game. Instead of starting from scratch, players rebuild their dream team and test it against the ultimate gauntlet of trainers from across the entire Pokémon franchise.

The game begins with the player arriving by boat at the World Stadium, where Professor Oak grants access to Pokémon, items, and team-building tools—no grinding, no filler. From there, the focus is purely on strategy, team synergy, and mastery.

World Stadium features roofed, competitive versions of iconic characters—Gym Leaders, Champions, Rivals, Villains, and special crossover battles—each rebuilt with smarter AI, optimized movesets, held items, and competitive logic. Every battle is designed to feel like a high-stakes tournament match, not a casual story fight.

There are no routes, no wild encounters, and no hand-holding. This is Pokémon stripped down to its most exciting core: Build. Adapt. Battle. Prove your team deserves the title of Champion of Champions.

Known Bugs

1. Do NOT use the SELECT button outside of the BAG menu.
2. Do NOT use the OPTIONS tab in the menu (restarts the game, so save often just in case your clumsy)
3. Mega Noivern SOMETIMES goes from level 100 to 98 once it mega evolves, but gains exp in battle and it instantly changes back to 100 after the battle.
