Extra Continue
Beat any trainer on any cup without any of your Pokémon fainting to acquire an extra continue for when you lose a battle.
Farfetch’d (Baton Pass)
Complete the Rival Cup for the first time. This is a rare and powerful Pokémon.
Gligar (Earthquake)
Complete the Rival Cup (Round 2) for the first time. This is a rare and powerful Pokémon.
Harder Mini-Games
Challenge the CPU opponents to a Hard seven-coin Mini-Game battle. This unlocks Super Hard difficulty.
Infinite Continues (Glitch)
Enter any battle and win the match. Then, suspend the gameplay. Pick a Stadium Cup and get at least one extra continue. If you lose the battle, you can suspend the game (you will be notified one has already suspended). When it appears, choose “Continue without Suspending”. This will let you rematch the Trainer without a lost continue.
Kanto Gym Leaders
Defeat the Elite Four in Johto.
Magnemite (Fire/Electric)
Place either a Gold, Silver, or Crystal GB game into the Transfer Pak. Start it up, then go to Oak’s Lab. Put a Magnemite into storage. By default, it is Electric/Steel. Turn off the game, and insert either a Red, Blue, or Yellow game into the Transfer Pak. Go to Oak’s Lab and redownload the Magnemite. Save, turn off Stadium 2, then load the 1st gen game. The Magnemite should now be Electric/Fire.
