[Question] Invalid legality in Gen 1

[Vladcik]

Heyah o/

So this time i'm just trying to understand how 90% of my Pokemon are flagged illegal in Red / Blue (when i don't allow the tradeback learnsets) :

So of course before i checked a little and found this thread :

 

But in that case it was talking about evolved Pokemon, and in my case it's affecting every stage. AND Moreover, the answer was about hacked stuff.

My Shiny wild have been caught with a Shiny Lock Patch for Gen 1, so i don't focus on them (even if the Venomoth is flagged as legal while got with the patch) but more on Pokemon like Voltorb / Electrode which i caught them without saving / restarting the game. One is flagged, not the other.

Nothing has been injected / haxed. Just moved from a box to another with Pkhex.

Thanks o/

There's no way to modify the Catch Rate byte unless you trade it to Gen2.

If the Catch Rate value does not match any of the possible encounter species, it's not valid (it can't ever be changed). Since the value is different, it was modified, hence flagged.

Well that's the thing I don't understand. I did nothing special with them. The Voltorb + Electrode are the two stationnary in the Power Plant (since they aren't locked). There's nothing i see wrong with catch rate value or anything ?

Thanks
