There is an obscure glitch in Pokemon Gold, Silver, and Crystal involving the move Beat Up, that might affect which Pokemon is able to land an attack and can potentially cause a desynchronization during a link battle.

In the pokecrystal disassembly, the error is located at https://github.com/pret/pokecrystal/blob/d0d61cb/battle/effect_commands.asm#L3194
The highlighted instruction should've been 'cp c' instead of 'cp [hl]'.

Credit to luckytyphlosion for originally finding this glitch and making me aware of it.
