How to make a pokemon Shiny if its from DX/Colosseum

[JestersGreed]

I have this Sableye here from XD and was wondering if It would be possible for it to be shiny even though It was previously a Shadow pokemon, It's legal now but I tried editing the PID TID and SID for shiny values and can't seem to figure it out.

Shadow Pokemon from Gale of Darkness can never be shiny. If you want to have a shiny Shadow Pokemon, you'll need to grab something from Colosseum.
