I could not help but read this thread. I would like to add my own input on this.
I'm a "naturalist cheater". I make sure everything I create or modify is 100% plausible in-game. Hell, I'm so anal about this that I seldom make hatched Pokémon simply because of the IVs not matching up to the PID. Now, here comes Generation V. Most, if not all of my resources on making legal Pokémon are now shattered by (what I believe to be) a change in the PID/Nature/IV/etc. relationships. Now, to put it simply...
...You guys already determined the changes made to 'Shifted Pokémon, discovered there are no new trash bytes, and discovered relationships from Generation IV are no longer necessary in Gen V. Would it really be that much trouble to discover how these new relationships work and make a Legal program for Gen V? It does not have to be an update; it can simply be a new program exclusively for Pokémon from/'Shifted to Gen V. I honestly don't care if it has event support considering I actually go to the events.
So, a new Legal exclusively for Gen V with no event support. Would this be more plausible for someone to make? Easier said than done, yes, but at least that person would not have to build Sabresite's Legal from the ground up.
