Arbitrary code experiment for Red|Blue: One byte of Bulbasaur's sprite constantly changes.

Notes: A save file here called Pokemon Red Bulbasaur sprite corruption.sav This program lets you see corrupted versions of sprites, using glitch Pokémon 0xE4's arbitrary sprite at CDE5. 4F works as a memory copier to grab a front sprite (Bulbasaur by default, but you can change it by modifying DA80 with the sprite pointer; locations in the SYM file ). It will then go into CDE5. If you use 4F while facing the exhibit, the game will automatically display it with simulated A and B presses, but displays glitch Pokémon 0xE4 instead of the fossil Pokémon, which will have the sprite specified in the code.

You also have to specify the dimensions, such as 55 (40x40) or 77 (56x56) or it will look wrong (You can also use custom sprites ^^ with the sprite import tools ). It combines work from RNG Plays Pokémon (thanks luckytyphlosion) ; which was modified to spam A and B, and custom sprites.
