Question: trainer and secret ID's

[aquaprofile]

Does a pokemon generated in pokegen/pokesav HAVE to have a legit Set of ID's as well as an Original trainer for it to be considered a legit pokemon??

And something about the trashbytes.. Are those directly related to legality of pokemon as well?

I heard that you need dif trash bytes as dif requirements like Wild pokemon and starters need different bytes..

one more thing:

Someone said that legality checker is an outdated program for only 4th generation pokegen. Can that still be used to check the trashbytes of a pkm file or is it untrustworthy?? Please help me! D:

Thanks in advance.

IDs and trash bytes aren't required for routine playthrough or vs friends.

a legal pokemon must have legal IDs and legal trash bytes, or else it is illegal (not generatable by the game)
