Some extra info if you want to have an 'easier' time hunting shinies in gen 2 VC

if you're willing to run around with eggs 24/7 looking for a hatched shiny in gen 2, without being able to do the ditto mimic thing, or if you have a mon you want an egg move on, the ONLY DVs you NEED are 0,8 or 9 HP, any attack, any speed, and the possible 10s in defense/special , HP is the most neccessary.

Since only the defense/special DVs are passed down by breeding ( to only opposite gendered children or all children with a ditto as a parent) you technically only need the 10s to make shiny hunting eggs a 1/64 chance, thus this makes using certain parents easier since they don't have to be shiny and for that they need to be male (starters, eevee, etc) you don't need a shiny parent to make shinies, its just that shiny parents are guaranteed to have the 10s you need, so they will make shiny babies easier to get

to explain the hp, hp DV is dependant on if the other DVs are odd or not, if attack is odd, it adds 8 to HP, if defense is odd, it adds 4, special 2, speed 1

so the max HP DV an any,10,10,any mon is 9, if both attack and speed are odd.

you can also use this info to help discern DVs once you narrow down HP

remember, each stat gives half as many HP DVs than the less stat, 8,4,2,1...

0 is nothing odd

1 is speed only

2 is special only

3 is speed and special are odd

4 is defense only

5 is speed, defense

6 is special and defense are odd

7 is speed, special and defense odd

8 is attack odd

9 is attack and speed

10 is attack and special

11 is attack speed and special

12 is attack and defense

13 is attack defense and speed

14 is attack defense and special

15 is all odd

Hope this helped!
