Spaceworld Demo - The Pokémon in slot number 255

Описание: A video of Pokemon 255 in the Spaceworld 1997 Demo. The quality of the video is poor due to recording issues with my computer, however, it may still be useful until someone else is able to provide a higher quality recording.

While I am unsure of the exact steps to reproducing it, I will explain what I did below:

Initiate a battle with a full Party against a Wild Smeargle. This allows me to obtain Sketch and use it to receive an invalid move.
I repeat the battle, this time hitting the Select button on both the invalid move and Transform before finishing the battle.
Before I start the third battle, I set slots 3-6 in my Party back to 000. Then, I encounter a Wild Unown and repeat using Select on the invalid move and Transform.
For the fourth battle, I again face a Wild Unown, but this time I end up with three Pokémon. The third slot now has a glitch Pokémon with the Dex number being 255. It gets its moveset from the Pokémon that was previously in the slot, in this case Bulbasaur.
The fifth and final battle is the results of having a Ditto transform into the glitch Pokémon. The game ends up not being able to find the proper Pokémon to transform into and ends up causing strange effects, like random Pokémon gaining a level and the battle mode switching to a Trainer battle. Sadly, the game cannot handle the mode switch and crashes.
