Just have been wondering if there is a way to disable encounters in any future generations. All I know about that is that in Generation 2 if you don't have any Pokemon you can skip the battles, but how would you get past the little girl in New Bark Town?
Indeed :), with the bad clone glitch or Coin Case arbitrary code execution
, we can obtain a ????? (FF).
To obtain a bad clone, I believe you must deposit more Pokémon in a box you have ever used (at least five) and then turn the power off a split second after the Yes/No box disappears (Gold) or the "SAVING... DON'T TURN OFF THE POWER." after it is fully printed (Crystal). If you are playing on Pokémon Stadium 2's GB Tower, you can reset the game when it says "Saving..." below the Game Boy screen. Once you have the bad clone (which should be level 0), withdraw it and take it into the Day Care to stabilize it, and if it is a 'bad clone' it will become a ????? (00).
To convert this glitch Pokémon into a ????? (FF), put it in slot 2 and use move Pokémon w/o mail to put a Pokémon in slot 1 to obtain 7 Pokémon. Take the ????? (00) into Day Care and out again, and you will receive ????? (FF); provided you deposit Pokémon to make room for it.
Then, once you have a ????? (FF), faint it, put it to the top of the party and faint all your other Pokémon below it. When you white out your Pokémon will not have been healed and you can disable encounters with the skip battle effect you mentioned. Ideally you can teach one of your party Pokémon Fly so you can travel across Johto and Kanto.
