Question about Pokemon Stadium 2...

[ClassicRockFan]

So yeah, I decided to try out some Pokemon on Stadium 2 and I noticed that my shiny Hitmonchan's Dizzy Punch was colored purple (The outline of the text was black, how it normally it, while the text was purple). I thought that this could be because of the Odd Egg "event", but then when I tried my Dratini with Extremespeed (Another "event" move), the text on Extremespeed was how it normally is (black outline with white text). Does anyone know about this and what it exactly means?

The game thinks the move is hacked, so it will detect some and some will be shown as regular
