What if i change my SID/TID of an existing save file

[KuroMokona]

Hello everyone,

i just have a question that i was wondering about for quite a while.
Since it is possible to change the SID and TID of a save file (p.e. a save file from HGSS), will the Pokemon i catch afterwards on this save file be counted as cheated or illegal mon by The Pokemon Company, Game Freak and the likes?
Because technically i caught them on an altered save file.
But the mons are otherwise obtained on a legal way.
Was just wondering about this.
If there is a difference in the legality between these types of Pokemon and the ones on a regular save file and stuff like this.
Would be pretty interesting to know.
Thanks in advance.

I'm not sure if there were any restrictions about which combinations of TID/SID were actually possible to get. You might have to consider that.

But besides that there's no way to tell if the Pokemon comes from a save with an altered TID/SID.

Thank you.

Yeah that would also be a pretty interesting thing to know. 
Because if there are certain combinations that are impossible to get then it would be suspicious if i had exact these values for my TID/SID. That's true.

I just checked. You can use Pokefinder to get a valid TID/SID pair.

Sadly i don't really get it besides the whole process that was described at the cute charm glitch guides but i don't get how i can find out if an existing SID/TID combo is valid.
Maybe i just approach it the wrong way. I really don't know.
But thank you anyways
