No offence, but (x) to doubt. Maybe you’ve not played a lot on them on something? Maybe one more intensive play and they’re dead. Anyway not here to discuss about this so let’s leave it at that.
In any case Gen 1 and Gen 2 events don’t have enough unique data points to truly be able to tell they’re the real deal. If we had the distribution hardware or software, at least we can sus the mon out based on generation protocols, but that probably would not be the case for Japanese Gen 2 events.
lastly, Gen 1 and Gen 2 events just ain’t unique enough, and they can’t carry whatever made them special forward. Heck, without hacking, you can’t even bring them into present Gen. there’s just too many factors against them. Might be nice to collectors to “own them”, but they’ll be forgotten real quick, for other more unique collection items.
