The Pokemon Victini, does not exist in any version made before Pokemon Black and White. Since it was released to catch in 2010(Japan) and 2011 (other places) it won't be able to caught in any other version before Black and White. Unless they made another event where you can catch Victini in other versions you could not catch it.
You can use the master ball the profser gave you or use the Ultra/Great ball And 2% of the time a standard pokemonball works.
you take them to pal park on Pokemon peal/diamond then you take them to the tempele in the snow go to the bottom floor and click on the big thing and it will battle you but it will be at level 70 it is a normal Pokemon and good luck
